Kind: captions Language: en ladies and gentlemen please welcome now to the stage Eric Zelenka good afternoon thank you for coming to our presentation today we're going to be talking a little bit about mac OS x server specifically the tiger server release and some of the new great features and capabilities that we are introducing in this in this version you've heard some of the capabilities talked about and some of the earlier presentations but there's plenty of other wonderful great features that we're going to go into today so as you know with mac OS and server we've been rapidly innovating upon this offering system for some time several years ago back in two thousand one was the first new release of mac OS x server that was the 10-point o version we introduced that at the 2001 developers conference later that year we came out with the 10.1 version had a a number of improvements and upgrades there at the same time we you know later that year we came out with the extra we now the xserve the extra platform it was a platform that a lot of people were asking for they wanted a purpose server a purpose-driven server they wanted something that they could mount in a rack that they could run this wonderful new great server operating system that we were building so in 2002 we finally shipped the extra and we've been innovating and consume deliver upon the xserve in allston that same year we delivered jaguar server so jaguar server was was a wonderful release for us we introduced a number of new capabilities not only from with open directory and netboot network install but a number of great features for education market and also higher education which was at that time kind of a new area for apple that was going into the enterprise more and more then just in 2003 we had some upgrades to the xserve who introduced the extra of cluster node which again was a purpose-built machine just for high-performance computing applications we also introduced the xserve raid massive amounts of storage Panther server was like if you're here last year we were talking about Panther server at that time this year we're talking about tiger server but Panther server continues to be these our operating system that we're shipping today in this presentation today we'll be talking about a lot of the capabilities that are in Panther server and then the new improvements that we continue to make on top of that other innovation that we've done earlier this year we ship the powermac I'm sorry the xserve g5 back in Macworld then also introduced the new xserve raid with three and a half terabytes of storage two new wonderful products that we're also introducing is apple remote desktop to everyone here should have a copy of apple remote desktop i encourage you to take apart your your kits when you get back to our hotels tonight install it on your systems and play with it this is a full release of a thermo desktop to it's a wonderful new upgrade and in the sessions later on this week you'll hear a lot more about it also xsan which is our storage area network file system for mac OS 10 and mac OS x server again there'll be a number of sessions about it later in this week and now tiger server let's get into a tiger server and talk more about what we're doing with the offering system but first how are people using this operating system that we've been building well let's look at some of the customer adoptions that are out there initially we had a lot of deployments in education on this picture here is of a high school district k to 12 high school districts they are doing a lot of servers I think miss Pacific situations a lot of network home directories this is a screenshot our affect picture of University of Tokyo this although there's no servers in that picture there are 1600 systems here all I max and their net booted diskless Lee off of our servers 1600 systems this closely net booted off of f of X you're a macro stun server here's another deployment in United Arab Emirates like again I think this is a video one Virginia Tech using a lot of the desktop management tools and utilities that we've introduced in the offering system core feature animation this is a shake render farm that's a they're doing videos animations all again using shake with mac OS x server the laboratory in singapore high performance computing computational clustering deployment another one in princeton this is an interesting one this is a space observatory in germany again taking a lot of data coming in off of satellite taking in data from their telescope systems that they have analyzing that data using the computational power that we have with the exurbs and the easy to use easy to manage operating system that we've delivered with mac OS x server even in apple's data center we're using on the server operating system if you've ever connected to you know dot mac and using some of the applications and services that are up there whether it's you know your idisk or those types of things you are connecting to our servers our server operating system it's kind of that drink your own champagne type of thinking and we've even got customers we're doing really crazy things with these servers I'm not sure what these guys are doing but they are having fun so that's the good news so we see our servers deployed in lots of lots of areas and we're trying to deliver a server operating system that's flexible that can be used for lots of different types of deployments I'm actually going to enterprise spaces there specific types of applications for specific purposes and you'll hear a lot of about those as we go on you've probably seen this slide a number of times this really is our strategy we are building upon standards open source and we're innovating upon that but if you look at our goals what are what are we really trying to do with this product well we're trying to make our server is easy to you is we want to make them very easy to set up and deploy especially if you've got you know a couple of them or hundreds or thousands of excerpts we want to provide a really good server for macintosh and windows environments there's a lot of departments a lot of work groups out there that can benefit from the services that we provide in this operating system we want to make it easy for our systems to integrate with existing networks and we want to take some of this open source movement that's going on innovate upon it integrate it test it and make open source very easy to use and so again you'll see that with throughout the product and as we talked about from the new features that we're introducing today so let's take a look at tiger server what we're delivering in tiger server first of all before we go into the new services within tiger server let's talk about the fundamentals of the operating system when we look at the the server operating system there's really two sections there's the core operating system decor OS that's mostly the Darwin or the BSD the low level components and then on top of that there are a number of services that we have built and we are designing and delivering so I'm going to talk a little bit about this server the core server operating system there are six major areas of the server operating system we have you know the colonel and the networking component our directory services and network and syndication layer which we've taken normally as a standalone service we've dropped that down into the core of the operating system the library's the utilities security infrastructures which normally would be like just a service as a standalone service ring on the OS we build down deep into the core of the OS and even high availability services so if you look at the colonel we continue to innovate on top of the colonel and and the Darwin architecture that we have it's combinations of you know various versions of VFD one of the new features that we're talking about here a lot is support for 64-bit applications so within Tiger server we now have the capability of running 64-bit applications and this is especially useful for our server customers who are you know doing lots and lots of number crunching they've got some very large numerics that they're dealing with they need to hold lots of data in memory at one time so now we can actually allocate up to 64 bits of memory and your application can take advantage of all of that on the networking side of the operating system we've got you know as Burt Ron mentioned in his presentation earlier today this is a BSc based networking architecture for server youths we have capabilities like I team multihoming so you can have multiple interfaces find multi p addresses to each of those various interfaces jumbo frames support for dealing a very very large packet innovative things like it IP over firewire so we can have high high bandwidth low latency interconnects one of the new features were introducing for the networking thank you and tiger server is support for Ethernet link aggregation and this is compliant with the 80 2 m3 ad standard and what this allows you to do is take multiple Ethernet links and aggregate them together so you have increased overall throughput to the server it also gives us a network interface failover so if one of those fate that one of those connections with physical connections were to get disconnected or or break or something happen to it the link can automatically fail over to to another cable or another link aggregate so this can be used with one ethernet switch it could be used with two ethernet switches this is a excellent this is an excellent feature for x 75 if you look in the next row of g5 we have two onboard gigabit ethernet port now with the the right type of switch you'll be able to aggregate those those ports together and get over a better overall throughput to your server I mentioned this directory services architecture that we call open directory that we've taken and integrated in to the core of the operating system this is a way of basically bottlenecking all user account and authentication or lookup requests bottlenecking them down deep into the OS so that if you're using one of the applications that Apple delivered or a service that we delivered or you're building an application or you're hosting your own application you can be using the same set of user account names the same sets of passwords that the rest of the operating system is using so we build this down beef into a tiger server also the other layer we look at is the unix fans and libraries there's lots of updates to these we continue to try and keep the server operating system up to date as much as possible with the rest of the goings on in the BSD world make sure that we have the latest open source components here but Tribble mentioned earlier are focused on security and making sure that the core of the operating system is very secure and again there's a number of different features and capabilities that we have for security and some of them are listed up here what's kind of different in the server operating system is some of the high availability components that we build in if you have a server you want your server to be reliable you want it to be up and running you know seven days a week 24 hours a day you don't want it to have any problems and if there are problems you want your server to you know do whatever it can to try and fix those problems and and they're not have those problems to begin with so there's some features that we deliver within the product for this as you know on the server operating system we introduced filesystem journaling a long time ago we have support for software raid capabilities tiger server we know house you know even raid 10 we have auto restart capabilities so your service if your service size we can restart your service if there's a problem with the entire server operating system the hardware can actually automatically restart one of the features we delivered a while ago was IP failover and we're introducing a kind of a next generation of IP failover today and we call it high availability clustering what this allows you to do is take two xserve that are connected to the same shared storage and have an active passive failover you can create what we call a cluster pair and you can create these pairs and have them do the same thing what we're awesome ating an entire server is support for network file services so your AFP your fists your NFS file services we're going to automate the the creation of these clustered pairs so you can have two servers if one of those servers were to fail or it was to go down the other server will automatically take over the responsibilities for that server and handling it its network file services so this is a great solution as you'll hear in presentation tomorrow morning there's also there's a really flexible architecture here and you can build your own custom solutions using this high availability clustering architecture the result so those are the six main components that make up the core of the server operating system and now I'm going to invite up Greg Byrne who's the senior director of the server and storage engineering team and Greg's going to take you through a walk-through of all the different services that were introducing in tiger server Greg so layered on top of the core OS and Mac os10 server is a services layer and that implements the services and the management that provides the server features of the product the services layer includes server administration to make management of all the services in mac OS x server easy we have directory services to provide naming and authentication to all the servers and clients on the network across platform workgroup and collaboration services client management to make management and deployment of clients macintosh clients on the network very simple internet networking services and new Integra server we have high performance computing clustering services so first let's talk about server administration the server administration facilities in mac OS 10 server integrate all of the many open-source products that we put into the server and make it easy to manage we have two main server management applications in mac OS 10 server server admin which lets you configure set up configure and monitor all the services in mac OS 10 server it also lets you manage multiple servers from the same console workgroup manager is our directory management application it lets you manage all the user and group accounts in the directory it's designed to work with open directory but it does work with any LDAP directory it also lets you manage all of these services that are configured out of the directories such as preference management for client management we're introducing a couple new management features in tiger server the first of which is access control list we have several types of access control lists in tiger server for the file system for services and for the directory now those of you that are familiar with panther server know that it uses unix permissions and unix permissions while they work well in simple cases have problems being mapped to real-world workflow if you have shared files on the network and you need to be able to set up groups of users who can write to those files and other groups of users who can only read them it's not really possible to specify that with UNIX permission so we have full support for access control lists in the files them to provide fine-grained control over those objects we also support other common features that you would expect from access control lists like groups within groups and full list of users and groups that can be assigned to the file system objects you can specify inheritance for the for the ackles and you can also have control over the default permissions of objects that are created in the file system now another area that it can be difficult in working with file systems and different permissions models is being able to work compatibly across multiple different types of file systems but because we support all of the features such as inheritance default permissions fine-grained permission settings and allows and I rules Mac os10 server and Mac OS 10 can be made to work in a compatible manner with windows server and with windows XP so it it simplifies working in a cross-platform environment we have other access control lists support in mac OS x server and other areas service circle in mac OS x server today is he has a server bound to a directory that has thousands or even tens of thousands of users and you set up a file server for instance every user account in that directory can log on to the server now you can control permissions file systems permissions to ensure that only the correct users get access to your data but in many cases you want to restrict that only to a core set of users and with tiger server we're introducing service ackles so that every user based service in the server can control the set of users and groups that can access the server you can have the same list for all services on your server or manage each server independently so that's service eccles and finally we have directory ackles which are global ackles that allow you to control who can access and update the contents of open directory and something an open directory that is different from other ldap servers is it stores these directory ackles in the directory itself to allow them to be propagated to the replicas by taking advantage of open directories replication so that's access control list in Tiger server another new piece where we have for management and Tegra server certificate management now you certificate management in 10 3 involved going into command line and it was different for each service and although it could be done it was sometimes somewhat cumbersome so we've simplified this greatly and tiger server we've added certificate management in the administration tools and you can use this with certificates that are signed by certificate authorities and you can also use Tigers new certificate assistant for self signing your own certificates in your organization you can display all the certificates you have available and assign them to services or websites as necessary so certificate management Integra server next up we'll talk about open directory open directory is Apple's directory and meaning service its standard space and it implements ldap naming services and it implements Kerberos for authentication we used openldap and MIT kerberos Kerberos is used to implement single sign-on which lets you log in once with one password it's never sent over the network and it's you get an authentication ticket which is good for all services in Mac OS 10 we also have a sport for what we call the password server which supports pass or replication to all of the open directory replicas on the network and this includes replicating all the Kerberos support as well so that you can have replicated Kerberos authentication across your entire network we integrate Samba with open directory as well to provide NT domain services for your Windows clients to allow them to authenticate as well with the same account information and of course we mentioned all the replication that's built into open directory we have a couple enhancements that we're putting an open directory and tiger server the first is managed network browsing now what is this in 10 dot 3 today if you have a large organization and you go to network you can get somewhat confusing and unwieldy and difficult to navigate and we fix that in Tiger Integra server by allowing you to control the contents of the network directory and you can see greatly simplify it and make it easy to navigate we provide virtual network views which can be controlled by the network administrator the view is defined instant in the math question server and it's stored in the directory so any client that binds to open directory will see the view you can combine both dynamic service discovery protocols for mac and windows as well as static entries that are stored in the directory and you can even have pointers to other entries that are outside of your local network that show up in the network folder and we make it easy to manage its managed through workgroup manager our directory management tool where you can create these views and preview to preview them so this greatly simplifies and makes it easier to set up the network folder in your clients to Mac os10 server and in Tiger we've also made some enhancements open directory some which include as we mentioned storage of the access controls in the directory another thing that we're storing in the directory itself is the ldap schema so the schema will now be propagated to replicas as well as the access control information so again this greatly simplifies managing multiple open directory servers and simplifies the replication process we're adding organizational unit supports so you can have multiple independent LDAP datasets hosted out of your open directory server we're improving the scalability we've tested up to 200,000 servers 200,000 records per server and we've added some tools that really help simplify the process of managing large open directory services we've improved search and apply so you can do batch editing of large number of records in the server as well as improving the import tool and in additionally since you need to backup all this data we've built in hot backup command line utilities that allow you to backup your naming authentication data based on the flash and we made some enhancement new security we have authenticated directory binding and the server and the client so that administrators can control who accesses the directory and you have mutual authentication between the client and server and we have the MTL mv2 authentication for windows clients to provide more security for windows client authentication another area of services in my question server is workgroup and collaboration work and collaboration services provide for sharing in work groups and the most common of these obviously are file and print and like we do today we support file and print sharing for math Windows and Linux clients this works for folders on the file server as well as home directories between mac and windows and sharing your network printers as well so all of your local work with resources these are fully integrated in mac OS x server all of the protocols can share the same SharePoint the same share folders they use the same access privileges the same account information so you set it up once and the files are accessible from all clients the Windows domain services are integrated as well so the windows clients have full access to all of the resources on the server we support windows roaming profile for home directory login and we have made of print services for both Mac and Windows clients we made some enhancements to work with services as well a couple of these are unified file logs now we have file locking today in mac OS x server but we've enhanced this to make sure that the file locking is consistent between all the protocols so that no matter what clients you're logging in from no matter what platform if you're accessing the same data you get consistent locking we've added we've added backup domain controller support which is exists today in Samba but we've added configuration for this and then management tools to make it easy to set up to provide we'd only failover for the Windows domain services for greater reliability and we've integrated the print services more directly with cups so that when you managed print services in server admin L you are managing the cups queues you're managing the cups printing we've eliminated some of the middle layers there and really tighter integration and services with cups and we've also added printf dedication so you can control active streak use we've added a few new services for work with me collaboration as well the first is the ichat server the tiger i chat server provides encrypted messaging for your intranet and a secure namespace it's based on jabber using the SMTP protocol and it provides cross-platform support obviously with Jabbar clients as well as Tigers I chat client and because it's integrated with open directory and provides a secure namespace for chat with in your local intranet we also have a weblog server that we're introducing Integra server as well a weblog is a way of easily publishing and syndicating information on the internet and what the web log server does is allow you to publish information and syndicate it using standard protocols like RSS or atom this morning you heard about Safari SSS or weblog server is completely compatible with our safari SSS as well as any other popular RSS reader we have a number of features that we support around style sheets and calendar based navigation that people who manage web blogs can control for their individual logs the logs themselves are automatically created as needed for user accounts in open directory and you can post to them directly from the web or from clients that support standard protocols like xml RPC or atom and another feature we have in mac OS x server and tiger server is the ability to have group web blogs as well so that people that are doing shared project web blogs can use a group account you know open directory to have to have multiple folks have write access to a weblog so now I'd like to have Eric come up again and do a quick demo of weblog service using tiger thank you Greg the weblog server that we've built into Tiger server is going to be a wonderful tool it's going to allow people to better syndicate or publish their content out to others but also allow a new way of our groups to communicate information I think one of the one of the benefits of RSS and and the syndication of information is it makes it really easy to you know communicate with the rest of the world part of the problem with it is how do I get that information out to the rest of world how can I publish this information I'm not an XML expert so how can I create this data and push it out to the rest of the world so let me show you how easy that is going to be in tiger server first of all I'm going to launch the server admin application so we're adding an application here I'm going to go in and in our for the web server it's very very simple i can go to the site that I'm hosting and I just with a simple checkbox I can enable the weblog server next let's go down to Safari and I'll open up safari here okay you log back in so I've connected off to the weblog server which is which is running on this this tiger server box here you'll notice a couple of things first of all this i have that i have calendar-based views so with most blogs you need to be able to go back it's time based information I can go to any dates here on the calendar and it'll show me the the entries that were created for that day I have ability to search within the various blogs search and return that content to me you also know categories that are available down here so as I i click different products I can get the the information that was posted into that category so first first thing I'm going to do is in this view right here would this be like the basic end user view they're just going up there they're just looking at the data within the browser notice that Safari up here displays the RSS so this is actually an RSS feed it notices that there's RSS information that's available here the links that are available at the bottom by clicking one of those I will actually see the the RSS information that is there and by clicking this in so far RSS it actually gets displayed I can also take this information and download it to the desktop and then or copy that RSS URL information or XML information put it into some other type of client so first thing I'm i do here is I'm going to log in now the login information here this is actually bound to a directory so I could be balanced to if the server's just writing locally it could just use the counselor on that local machine as reg mentioned the server is typically going to be integrated with an existing directory system so we can take advantage of the user accounts the namespace is already created for you and it within the network so i'm going to log in here hopefully i remember the right name and password i did i have the ability now as as the owner of this area of this weblog of creating a new category so i can here's the new category here so i'm going to create a new category and i'm going to you know name this after i chat because i'm going to go and i'm going to create an ichat entry the next thing I do is I'm going to go and I'm going to make an ichat entry so I'm gonna pick the appropriate category here and I'm going to go grab some some text so Steve made me famous this morning for doing a video conference at 35,000 feet unfortunately I'm not famous for my product but that's ok so I'm going to take this information here you know a little bit of text here we copied some of this and just paste the simple text in and hit save and then automatically I get an update you'll notice that the weblog stover gives the feedback to the user that says that their web log entry is was created as users read this they can post comments to each of the individual entries and as an administrator also have the ability to go back edit this information and delete it at any time that I see fit so this is the new weblog server in Tiger server thank you so that's work open collaboration services now let's move on to client management client management services in math question server let you easily deploy and manage large numbers of Macintosh computers we have client management services that let you control preferences and capabilities on the client this is called directory based management or preference management this is deployed via open directory and it's configured from the workgroup manager application in mac OS x server we also have system imaging services that make it easy to set up and deploy software on systems throughout your network netboot lets you configure a single image or a small group of image and boot network systems from them from the server you can also use net install to install those same images to systems that are on the network as well we've made a few improvements to system imaging and tiger server the first of which is when you create these images we now configure the open directory configuration for your network in the images to make it easier to deploy the images without having to tweak open directory settings afterwards we also are supporting block coffee for software installs and net installs the greatly in speed in essence and lastly we're allowing you to create bootable DVD images from your net install images so you can install those images on systems that are offline off the network we have a few other services that we're adding the client management the entire server the first of which is mobile home directories mobile home directories lets you take user files account and other information that pertains to your home directory and sync is between a portable and a network home directory this synchronization occurs when the portable is connected to the network it occurs in the background with trickle sync and when your affordable is offline and these files are updated the files in your home directory in your document folder your preferences and their updated when you connect back to the network to the home directory they'll be synced back up to the server so this allows you to maintain consistent information between your portable and your network home directory server and it also allows you to have a backup of the contents of the portable on the network in case it ever becomes lost and because the account information is synchronized as well between the portable computer and the network the single sign-on on the network is also brought down to the portable when it's offline because all the account information and the authentication information is synchronized as well so that's mobile home directories and tiger server and software update server we heard in the earlier session allows you to deal with an issue that we have to date where we have a lot of software updates that make it very easy to maintain the latest software on your Mac os10 systems it makes it very convenient but when we have a new update like a Mac OS 10 10 34 and you have everyone in your organization downloading that update the day it comes out it can create a real strain on your network bandwidth so software update allows you to use mac OS x software updates but by providing a proxy cache server for software updates also conserve network bandwidth and makes it easier for you to get those updates into your organization it's totally transparent and automatic when software updates become available they're downloaded to the server and made available to the client but you have control as well some sites like to test the updates to make sure it works with their internal software before they make them available for deployment and so you can either choose to make the software updates automatically available to clients as soon as they're posted or you can make that step manual and test the updates yourself and then release them once you're satisfied that they work with your internal applications software update server the internet and networking services in mac OS x server allow you to manage your network and host application which is web services mail and java application services for networking for in mac OS x server we support dns for domain address name management DHD for IP address assignments nap for connecting to the internet and for sharing I IP addresses among systems we support firewall for securing your connections of the internet and we support VPN to allow remote clients whether they be mac or windows to access services on your network securely from a remote location we've made a few enhancements to networking services Integra server the first is site to site VPN if you have multiple sites and you want to have a secure land virtual land between them we allow you to set up site to site VPN between these sites we do this over the Internet securely with ipsec we improve server management with dhcp by allowing you to manage systems that have multiple network interfaces and handled address assignment for those systems as well as handling static IP address assignment in server admin as well and we've improved the workflow for DNS management we've greatly simplified that over the 10 dot 3 release another area of networking services that can be somewhat difficult is setting up internet gateway services this is fairly complex or a number of services that all happy has to be configured consistently with each other and we've simplified this Integra server through the Gateway setup assistant this sets up everything you need for an Internet gateway so it configures or dhcp and your VPN address ranges map port routing the firewall VPN and it doesn't in just a few simple steps and so this is ideal for small side small businesses that have a connection to the internet for remote sites that share one dsl connection to the internet it makes it very easy to setup the server as an Internet gateway so I'm going to ask Eric to come up again and demo this and show you how simple it is one of the things that we want to make easy in tiger server was to make it make it much easier to set up complex networking services on a lot of people are trying to use servers for port routing or they want to have it one port on their server the poor connection now for the the LAN another port for connection onto the land but they've got all these different services that they need to configure you've got your DNS your dhcp you've got your firewall you might be running a VPN you've got a set of port mapping that there's a lot of different services so in Tiger server one of the things we're making it much easier to do is set up easier to setup and these are all these spirit different services so within the server admin application you can now select the gateway set up tool what this will do is it set an assistant there we go and try that again there we go so the Gateway is set up a distant tool allows you to configure your server for use as a gateway it's a very simple assistant kind of walks the user through what needs to be done to the server so the first thing you're going to do is select which port you're going to use as your ear port for the LAN this might be a cable modem broadband connection using dsl or or those sorts of things next you're going to configure which land port so if you have an extra when you have another building give Ethernet port that might be something you select here obviously I'm on a desktop system here so I don't have multiple built-in ethernet port then what the network then what the internet gateways set up a system is going to do is it's going to give me a summary of the configuration changes it's going to make so it tells me here's what I'm going to do I'm going to set up this port I'm going to turn on port port mapping i'm going to configure your dhcp server i'm going to set up NAT I'm going to turn DNS saw on for caching and if I hit apply here it's actually going to reconfigure this machine so i will lose some networking capability here and now it's done so now what i can do is i can go back into the server admin application and within this application a number of services have been turned on for me so i can go into the firewall i can go into its settings i can see that the firewall settings have been automatically configured for me within dns i can see that here nat is stopped there now it's running but what it does is automatically configures up each of these services for you so again another really innovative feature that we're delivering and tiger server make it very easy for people to use these complex network services okay [Applause] internet services in mac OS x server we we had a broad range of Internet services intended three and of course we carried these forward Apache for web services the most widely deployed web server in the world we have integrated mail services that are based on a number of open source projects postfix for mail delivery Cyrus for imap and mailman for list management we've integrated these all together they're all integrated store open directory for account management and through server admin for management and configuration we have quicktime streaming services that allow you to host streaming media or video on demand as well as live media that streams as well you can use QuickTime broadcaster to encode the live media and reflect it through the QuickTime streaming server and we have Q GS s publisher which lets you manage your content on the QuickTime streaming server if you're building enterprise Java applications we support j2ee through jboss and apache tomcat and if you need to host a back-end database and link it in your websites we include mysql as well we've carried these two verses forward and we've provided some enhancements to tiger server as well the first is in the area of mail services where we've integrated junk mail filtering and virus filtering into the mail server with spam assassin an open source project that we've enjoyed we've integrated this in with our mail services and we've also integrated all of the management in the server admin so it's very easy to configure and shut up we sport virtual domains now for the mail server where we allow you to set up multiple virtual male domains so if you have for instance company 1 and company two on your server you can have the same male name sales @ company 1 or sales at company to go to multiple independent mailboxes on the server we even enhance the support for mail quotas so you can have soft quotas with customizable messages as well as hard quotas that will actually stop delivery of mail to mail boxes that are full we've also delivered some enhancements to quicktime streaming we've enhanced the qts publisher for improve the workflow and added Apple script support and we've enhanced the scalability of quicktime streaming to support bit rates that can now deliver HD quality on local internet with our latest codecs that's Internet services integra server and lastly another area that you've heard in the previous sessions a bit about today this high-performance computing with grid grid clusters and we have previously released a technology preview of technology we call experts and we're improving that and product sizing that in Tiger server X grid will provide software that you need to provide clustering in macro Stan and macro stem server you can do that through a dedicated set of ex-service Turing nodes or you can also use X grid to harvest their CPU cycles from desktops that you have in your network when they're not being used for ad hoc clustering X grid will have an SDK that allows you to embed awareness and use of the grid into your applications it also works with command-line applications so that you can distribute command-line jobs that have no inherent awareness of the grid of the cluster we provide management tools that let you set up the grid through server admin and manage your systems and you can manage job and job submission and node status from any client on the network and like all of the other services and tiger server it's integrated with open directory for security so those are the services layer in that integra server in mac OS 10 server server administration directory services workgroup client management internet and high performance computing we've talked about a few of the major features that we're introducing here today 64-bit applications access control lists mobile directories there are a lot more we don't have time to go through a mall we've actually added about 200 new features in the server and in Mac OS 10 server we have about a hundred open source solutions that we've integrated we've integrated all of these by integrating them with open directory so they share the same account information the same authentication information and we've integrated them through server admin so they have the same management they're easy to set up and do bigger so Tiger server so next I'd like to point you to a few sessions related to the server there are actually quite a few in the IT track this week so not going to list them all but here are a few that you shouldn't miss they'll call out and you can check your schedules to the rest tomorrow morning is inside Mac os10 server tomorrow afternoon if you want to find out more about file system access controls there's a session there on Wednesday we have a session on developing 64-bit applications we have sessions on desktop management technologies in now for remote desktop for our client management as well we have two sessions on Wednesday for X and some sessions on directory services on Thursday and network authentication for j 3 and java programming on the server we have a session on jboss on friday and we have a session on distributed computing with exquisite clustering services from a question server on wednesday afternoon if you have feedback we have a feedback form for the server tomorrow afternoon and like it may have been moved so check your calendar and we have enterprise feedback forum as well so if you read more information there is the release notes and documentation will be posted for tiger server as it becomes available on the Apple Developer connect site and you can get the current documentation for the server product there as well
