  • This release includes platform enhancements as well as management enhancements <br /> On the platform, we&#x2019;ve increased our supported memory and processor limits by 2x <br /> We&#x2019;ve touched up our XenCenter administrative console to make systems easier to manage <br /> We&#x2019;ve made XenServer an even better platform for Citrix XenDesktop, the market leading system for virtualization on the desktop <br /> Finally, we&#x2019;ll be putting XenServer through Common Criteria certification, and I&#x2019;m sure that hose of you in government or high security environments will be pleased to hear that. We expect to complete this process later in 2010 <br /> <br /> With XenServer Enterprise Edition, we&#x2019;ve added some new management functionality, including role-based administration & audit trails. We&#x2019;ve enhanced the snapshot functionality and workload balancing. And we&#x2019;ve enhanced the flexibility of environment by supporting Flex Migration, which enables resource pools to have different generation servers. <br /> <br /> In the Platinum edition, we&#x2019;ve added Site Recovery, which enables recovery of an entire virtual machine infrastructure to a secondary DR site, and self-service portal functionality so that VM users and administrators don&#x2019;t need to be provided access to xencenter <br /> <br />

  • Though not a feature per se, it&#x2019;s important to note that XenServer 5.6 moves to a new licensing system. We&#x2019;ve ceased using the legacy file-based system for XenServer Advanced/Ent/Plat , and are now using the Citrix Licensing Server. <br /> <br /> The key point is that licensing is much more tightly enforced than before. So if you are considering an upgrade from 5.5 to 5.6, make sure you have all the licenses you need available to you in your mycitrix.com account. <br /> <br /> You can run the Citrix Licensing server on a Windows VM, and customers often co-locate services such as Workload Balancing and StorageLink on the same VM. <br /> <br /> We do also plan to release a Linux virtual appliance, though this is not part of the beta. <br /> <br /> Note that for Free XS, we&#x2019;ll still use the legacy file-based approach which is very simple and does not require a license server / VM. <br /> <br />

  • We&#x2019;ve also added some initial SR-IOV NIC support, which has enabled bandwidth for certain workloads like NetScaler VPX to be increased. We can get throughput of up to 108 Gbps <br /> One of the key workloads is XenDesktop, and scalability is enhanced by: <br /> Increased support limits; up to 130 Windows XP guests per host has been documented <br /> Auto-adjusting Dom0 memory configuration to support kind of scale <br /> <br />
  • Dynamic Memory Control.&#xA0; Let&apos;s say you have a few XenServer hosts.&#xA0; You need to spin up some more VMs, but your VMs are configured to use all available resource pool memory.&#xA0; However, you know that some of the existing VMs aren&apos;t using all the physical memory you&apos;ve allocated.&#xA0; With XenServer 5.6, you can set memory ranges for VMs so that you can squeeze the physical memory used for existing VMs in order to let new ones on.&#xA0; If you find that one or more VMs operating near the lower limit requires more memory, you can increase the minimum level on the fly without rebooting. <br />

  • If you have a XenApp farm running 24x7,there is quite a bit of power wasted by those servers during nights and &#xA0;weekends when only a handful of users are accessing applications.&#xA0; Workload balancing can be scheduled to consolidate all of your idle XenApp servers on as few hosts as possible while powering off the newly vacated XenServer hosts. In the morning or after a weekend, those machines will power on and the VMs will be redistributed to handle the load.&#xA0; Additionally, Workload Balancing includes a fully-automated mode with some new configuration options.&#xA0; Example: if you have some VMs that you don&apos;t want moving around, simply start those VMs on a specific host and exclude that host from WLB computations.&#xA0; <br />

  • A key new addition to StorageLink is Site Recovery. Site Recovery simplifies the setup and configuration of disaster recovery for XenServer VMs by integrating with array-based DR controls for replication, fail-over, and testing. <br /> <br /> Controls for setting up replication are the same regardless of which array you&#x2019;re connected to, and array specific attributes (such as whether or not replication is based on a LUN basis or POOL basis) depends on the array manufacture and array setup. <br /> <br />

  • Let&apos;s say you have a pool of 5 XenServer hosts, which run on year-old hardware with Intel Xeon 5400 processors.&#xA0; Now you buy a couple of new servers, which have new Intel Xeon 5500 processors.&#xA0;With XenServer you can join them to the same pool and enable XenMotion, HA, Shared Storage, and Workload Balancing.&#xA0;In the past, you could "force join" the newer servers to the existing pool, but you&apos;d have to be careful not to XenMotion between different processor types. <br />

  • This isn&apos;t "new" per se, however it&apos;s starting to matter a lot more when you compare costs of XenServer and vSphere on some of the latest servers.&#xA0; Dell R815 and HP DL385 G7 servers now ship with 12-core Opteron 6000 processors. &#xA0;&#xA0;The problem for VMware customers is that they won&apos;t allow you to run vSphere Standard or Enterprise Edition on those servers.&#xA0; In other words, VMware hates Moore&apos;s Law.&#xA0; With XenServer, we don&apos;t care how many cores or sockets the server has; you pay the same price with any configuration. <br />
  • The legacy Linux P2V tool in the installer is gone, though it wasn&apos;t of much use any more since it only worked for very old distros.&#xA0;We&apos;ve also dropped Debian Etch (4.0) support since it no longer receives security updates.&#xA0; Those of you who look closely might find that the new "Demo Linux VM" template is, shall we say, eerily similar to Debian Etch.&#xA0; It&apos;s not recommended for production use, and we have this solely because so many of you told us you liked the built-in Linux distro for testing and demonstration purposes. <br />

  • Store Management Wizard 06/06/10 © 2010 Thomas Krampe 31
  • Store Management Wizard - New wizard allows you to leverage the Read-Only vDisk Store capability without having to go to the command line on each server. - Stores are marked as “managed” during the creation process. - Toggle store between Read-only and Maintenance mode and select server for vDisk maintenance (server maintains write access to store volume). - Store cannot be placed in maintenance mode if there are active vDisk connections. 06/06/10 © 2010 Thomas Krampe 31
  • Enhanced AD Support 06/06/10 © 2010 Thomas Krampe 32
  • Enhanced AD Support - AD integration was has been enhanced. - Provisioning Services now supports deployment in multi-forest environments. - The following slide show supported configurations 06/06/10 © 2010 Thomas Krampe 32
  • Enhanced AD Support Szenario Supported PVS and vDisk store in parent domain, targets in child yes domains, single forest PVS and vDisk store in a child domain, targets in different yes child domains, single forest PVS and vDisk store in on forest, targets in forests yes PVS and vDisk store in on forest, targets in forests in testing PVS and vDisk store in on forest, targets in forests in testing 06/06/10 © 2010 Thomas Krampe 33
  • Subnet Affinity 06/06/10 © 2010 Thomas Krampe 34
  • Subnet Affinity - The load balancing algorithm will now consider the network on which the request was received and select the IP address of the server on that same network. - If there is not a matching network then it is assumed that networks are routed and round-robin is used to select the IP address. 06/06/10 © 2010 Thomas Krampe 34
  • Load Balancing 06/06/10 © 2010 Thomas Krampe 35
  • Load Balancing Power Rating A user defined constant indicating the relative level of the power of a server to service PVS devices. All other constraints being equal, a server with a power rating of 2.0 should service twice as many devices as a server with a power rating of 1.0. Load Factor A normalized count of devices assigned to a server. The count is normalized by dividing the device count by the server “Power rating”. Fair Load The relative load a server should share for a given vDisk and device set as determined by the relative power ratings of all servers involved. Automatic load balancing approximately every 10 minutes 06/06/10 © 2010 Thomas Krampe 35
  • Jumbo Packet Support 06/06/10 © 2010 Thomas Krampe 36
  • Jumbo Packet Support - Now supported on a per server basis. - Console changed for Maximum Transmission Unit (MTU) - PVS server maximum MTU: The lowest MTU of all PVS server network adapter Ethernet MTU. - PVS client maximum MTU: The MTU of currently active network adapter that binds to BNNS. When NIC failover occurs, new NIC MTU is exchanged during reconnect. - In PVS client preboot, PXE/TFTP/UNDI(int13) do not support jumbo packets. 06/06/10 © 2010 Thomas Krampe 36
  • Other New Features 06/06/10 © 2010 Thomas Krampe 37

  • XenServer Host Streaming Technology Preview 06/06/10 © 2010 Thomas Krampe 38
  • XenServer Host Streaming Technology Preview - Standard and private image mode streaming of diskless XenServer hosts. - Non-supported technology preview. Supported implementation planned for Q4 2010. - Citrix need your ideas and feedback! 06/06/10 © 2010 Thomas Krampe 38
  • XenServer Host Streaming: Architecture 06/06/10 © 2010 Thomas Krampe 39
  • XenServer Host Streaming: Architecture - General architecture XS host is retained. - Two kernel drivers: - Proprietary module which implements the PVS protocol - Public module which implements the GPL glue between the proprietary module and the kernel - Both drivers interact with the SCSI subsystem as a SCSI LLD to register a SCSI disk and redirect access to it over the network to the PVS server - Initial ram disk image handles boot time - User space magic is carried out by several scripts 06/06/10 © 2010 Thomas Krampe 39
  • XenServer Host Streaming: Installation 06/06/10 © 2010 Thomas Krampe 40
  • XenServer Host Streaming: Installation - Installation is done in text mode and into a hardcoded path. - eth0 must not be designated as the management interface or support a VLAN. - During installation, eth0 is removed from under the control of XenServer and allocated to PVS exclusively. - Original boot loader, extlinux, is retained. - PVS specific entry is created in the boot loader configuration file and is selected as the default boot option. 06/06/10 © 2010 Thomas Krampe 40
  • XenServer Host Streaming: Imaging 06/06/10 © 2010 Thomas Krampe 41
  • XenServer Host Streaming: Imaging - Like the installation, imaging is also done in text mode. - As a result, partitions “/boot” and “/” are created. - The native boot loader, extlinux, is not carried over to the virtual disk. Instead, the GRUB boot loader is used. - Personalization is attained through a startup script a symbolic link to which is added in runlevel 3. - A custom initrd, which contains needed drivers and startup scripts, is created on the virtual disk. 06/06/10 © 2010 Thomas Krampe 41
  • XenServer Host Streaming: Personalization 06/06/10 © 2010 Thomas Krampe 42
  • XenServer Host Streaming: Personalization - Needed because each XenServer instance is tied to the hardware on which it is installed. - Performed before XAPI is running. - Data is injected directly into the XenServer database and several other configuration files. - Methods used to personalize a XenServer instance entail: - Patching of the last six bytes of some UUIDs with the MAC of the PVS interface - Removal of any references to local storage - Updates of network configuration files with MACs of corresponding interfaces 06/06/10 © 2010 Thomas Krampe 42
  • XenServer Host Streaming: Personalization 06/06/10 © 2010 Thomas Krampe 43
  • XenServer Host Streaming: Personalization - Files affected are: - /etc/xensource-inventory - /var/xapi/state.db - /etc/sysconfig/network-scripts/ifcfg-eth<N> - Values affected are: - installation UUID - dom0 UUID - host name, host UUID and host reference UUID - pool UUID and pool reference UUID - MAC addresses of all PIFs found in the Xen Server database - all references the local physical block device (PBD) 06/06/10 © 2010 Thomas Krampe 43
