Although the product is primarily based on PowerShell, there is still an engineering effort involved to support Server Core and we haven’t received adequate demand from customers.Refer to Citrix eDocs for the latest details on system requirements.
14 Supported database platforms SQL Server 2012 SP1Express, Standard, and Enterprise editionsSQL Server 2008 R2 SP2Express, Standard, Enterprise, and Datacenter editionsDatabases are supported in standalone, clustered, and mirrored modes (except the Express Edition, which supports only standalone mode)AlwaysOn Availability groups is supported for SQL Server 2012Windows authentication is required (SQL authentication is not used)Earlier versions of SQL Server may work but have not been tested and are not officially supported.SQL Express should only be used for PoC and test environments. It is not ideal for production because it doesn’t support high-availability options (hypervisor high-availability can be used but is not practical due to the time required to restart the VM on another host). It also has resource limits on the size of the database and amount of CPUs and RAM that can be used. Refer to for additional details.

19 Getting toXenDesktop 7Upgrade in place, or build new?
20 Making the move: Migration paths from existing deployments Current ProductPath AvailableXenDesktop 5.xIn-place upgradeXenDesktop 4.xMigration toolXenApp 6.5New deploymentXenApp 6.0XenApp 5.x & earlierWhen performing a new deployment of XenDesktop 7, it is possible to have a single Storefront front-end that aggregates applications and desktops from one or more XenDesktop and/or XenApp versions at various levels.Refer to eDocs for details on the suggested upgrade strategy and steps from XenDesktop 5.x to XenDesktop 7.Upgrading from a Tech Preview version to the full RTM version is not supported.A migration tool for XenApp 6.5 applications and policies was originally on the roadmap for H2 of 2013, but has been pulled in favor of “App Orchestration” functionality that will come in Merlin.
21 One disk/iso to install all XD7 components Meta-InstallerOne disk/iso to install all XD7 componentsExcalibur uses a .NET-based metainstaller, which is somewhat similar to what was used in XenDesktop 5.x though with a different look and feel. The Delivery Controller option is the primary means to install the product and core components. We will choose that one and proceed here. Other options include installing the Virtual Delivery Agents for server and desktop OS's, installers for specific components, and links to documentation.
22 New Environment Installation: Process Flowchart For current XenApp customers migrating to XenDesktop 7Step 1Install the controller, Studio, license server and databaseStep 3Install the Virtual Delivery AgentsStep 5Publish Desktop Groups/ApplicationsStep 2Install and configure DirectorStep 4Use PVS or MCS to create catalogsStep 6Install and configure StoreFront and ReceiverThese are the general high-level steps. Typically, SQL server will already be setup in the environment. Provisioning Services will need to be setup if using it to stream OS workloads.
23 Upgrading an existing XenDesktop 5.x environment (in place upgrade)
24 In Place Upgrade: Process Flowchart For current XenDesktop 5 In Place Upgrade: Process Flowchart For current XenDesktop 5.x customers migrating to XenDesktop 7Step 1Install and configure StoreFront and ReceiverStep 3Upgrade Provisioning Servers (if applicable)Step 5Upgrade ONE Delivery Controller then backup databaseStep 7Upgrade remaining Controllers and register in StudioStep 2Upgrade the License ServerStep 4Upgrade Virtual Delivery and PVS AgentsStep 6Run Studio, follow “upgrade site database” dialogIf you have an existing XenDesktop 5 or higher environment, you can perform an in place upgrade, with minimal disruption to users. At a high level these are the steps.First you must have migrated your Web Interface to Storefront and configured Receivers to point to the new Storefront environment.The License Server should be at the version that ships with the XenDesktop 7 media. You may have to obtain a new license file to confirm your SA date and validate your rights to XD7.Upgrade PVS servers first if they are in your environment.Upgrade the VDA’s in your VDI hosts as well as the PVS agents. You may need to build net new base images with these new agents. XenApp customers migrating to XD7 Apps Edition will need to build new Windows Server worker images.Upgrade ONE delivery controller in place, reboot if required.Backup site database.Run STUDIO, you will be prompted to Upgrade Site Database. This must be done to complete the upgrade process. Do so only if you have a good back up of the database.Upgrade and reboot the remaining delivery controllers, reboot them, and register each in Studio.
25 No direct in-place upgrade to XenDesktop 7 from XenDesktop 4.x Problem statementNo direct in-place upgrade to XenDesktop 7 from XenDesktop 4.xDatabase and architecture changesOperating system requirements are differentEnvironments need to be setup from scratch which can result in a considerable amount of time (especially for larger enterprise environments)Problem: can’t upgrade directly from XD4 to XD 7 (new architecture from XD 5.0 onward), MSI can’t patch onto it.Need to create a new site then recreate settings.Migration tool designed to help automate the bulk recreation of desktops, user assignments and policies.XenDesktop 5.x supports a direct upgrade to XenDesktop 7.0 whereas all versions of XenApp require a clean installation to be performed.
26 Migration Tool Highlights Provides the ability to export settings from a legacy XenDesktop 4.x farm and import them into a XenDesktop 7 siteConsists of two componentsExport Tool – Executable used to write the legacy farm settings to an XML fileImport Tool – PowerShell script used to import the settings from the XML fileShipped with XenDesktop 7
27 What settings can we migrate? Desktop Groups (icons are not exported)DesktopsMachinesPool management poolsFarm settingsPolicies (including session printers)User assignmentsHypervisor settings (connection credentials are not exported)These settings are both exported and imported.Note that the XML schema presents the XD4 object model and terminology rather than XD5 : e,g. farm contains desktop groups, which contains hosting settings and a set of desktops.Aimed to be readable to the XD4 admin who’s not yet familiar with XD5More details on what can and can’t be migrated are available on the eDocs site
28 What settings will export but not migrate? AdministratorsLicensing configurationDelivery group folders (don’t exist in XenDesktop 7)Registry keys (vary in XenDesktop 7)Some settings are exported but not importedAdmins – Jeroboam folder based permissions are also exportedLicensing – The farm settings for license server, port and edition are exported. Settings for the license server itself are not exported, such as license files.Desktop group folder is exported as a path from a root specified as forward-slash.Some per DDC registry settings are supported in XD 7, however these aren’t imported.
29 What settings can’t we export or migrate? Provisioning Services dataApplicationsList of Desktop Delivery ControllersWeb Interface configurationAD OU configurationPortICAConfig XML fileConfiguration logsIn general the exported settings are limited to those configured through the CMC/AMC and stored in IMA.Exporting Cosmo applications was not a requirement.Farm BaseOU setting is exported, but actual content of the AD OU is not exported.PortICAConfig XML file settings are not applicable in XD 7 for which the VDA now draws default values from FullArmor policy. In the event customizations have been made, these will need manually recreated in XD Jasper.
30 Final thoughts StoreFront is a MUST, and it is the starting point License Server upgrade is a MUST, and you will likely need to obtain a new license file from Citrix (to verify/update your SA)Once on XD7 future upgrades should be much easier than the IMA days of XenAppEven if you can upgrade XenDesktop 5.x in place, it might be better to simply build a new environment in parallel

40 I was inundated with data I was inundated with data. Chart after chart after chart was pouring in until all I was seeing was a blur of lines and hazy circles consuming endless expanse of the screen. I needed a break from the brutal monotony of cubical life. The thought reminded me of my father taking us camping in the forest where we could sit and hear nothing for else but our thoughts. The break would cut through whatever fog our heads were in. Alas, the thought of that freedom was just that and the harsh reality was that this stack of dead trees needed to be in a report by tomorrow with insightful commentary. A visit to the coffee machine was due and then it was right to work. I wish I had the right set of tools for this job…InsightIntro slide – to Insight -> story abt visibility and need for visbility – moving towards disaggregation of apps (remove the slide)

This has 2 advantages over XD doing it (which is how it works if the facility id not available):Rebooting via the hypervisor tools also cleans the image (so you can use XenCenter to power manage the machine with the same effect that it would have via XD studio)The hypervisor understands the context for the operation and can clean up any data that is no longer needed as part of the process itself (at a point that is best for the hypervisor). When XD has to do this the deletion of the old data is offloaded and cleaned slowly to avoid unexpected load on the hypervisor which means the data can hang around for a while and it has been known for storage to be exhausted as a result. Essentially making the operation just much more efficient when using the hypervisor to perform it.As of XD7 both Xen and ESX provide clone on boot function and it is only Hyper-V that XD is required to perform the operation.

58 PVS Where is my PVS? PVS is not going away Continuing to be improved Still considered the primary and optimal solution for large deploymentsDownload is underthe XenDesktop 7 ‘Additional Components’ sectionThe XenApp 7 FP2 downloadsI might say 500 or 1000 seats, but it's sort of a nebulous number because we can technically make MCS work with thousands of desktops, too! We actually have an MCS deployment in the 4-6k range in EMEA. But you just have to be willing to "pay" for MCS in terms of IOPS. It not only changes the IO profile from the typical 90/10 W/R ratio of PVS to 45/55 with MCS. But it also introduces about 20-30% more IOPS in the steady state compared to PVS...and about 50-60% overall if you factor in the boot and logon phases.

85 NetApp Flash Recommendations for VDI Lead with FAS w/ Flash Cache or Flash Pool for typical task workers and knowledge usersTypically <20 IOPS per userAny capacity requirementPosition EF for low latency use casesFAS required for CIFS user data and profilesAnnouncing partnership with Atlantis Computing to more cost efficiently enable VDI for power users (typically 20+ IOPS; low latency)DevelopersHigh graphics & CAD usersHealthcare PACSEF with Atlantis Architecture WhitepaperCustomers IOPS and capacity requirement per virtual desktop can fall in any range based on the user profile. IOPS requirement can be as low as 8-10 IOPS per desktop for task workers and be high as 50 IOPS per desktop for power users like software developers, high graphics and CAD/CAM users, etc.Regardless of the IOPS or capacity requirements, customers want VDI at the lowest possible cost. We have developed new guidance to help customers deploy VDI at lowest possible cost while maintaining excellent user experience.[click]For task and knowledge workers, typically up to 20 IOPS per desktop, our recommendation is to lead with FAS platform w/ either FlashCache or FlashPool.For extremely low latency use cases, you could position the EF All Flash Array.Please note that FAS array would be required if the customer VDI requirements include buying storage for CIFS shares to host user data and profiles.To cost efficiency enable VDI for power users; typically IOPS per desktop, we are announcing partnership with Atlantis Computing.Some examples of power users that require extreme IOPS are: Software developers, High graphics & CAD/CAM users, Healthcare PACS & Telemetry.For these extreme IOPS use cases and any capacity requirement, our recommendation is to lead with EF and Atlantis Architecture. Great news is that we have the NetApp EF and Atlantis reference architecture available today where we demonstrate that a 2U EF540 All Flash Array w/ 12 SSDs and Atlantis ILIO Host side IO optimization software can support 100K IOPS (80% writes; 4K-8K block size). This architecture can cost efficiently meet the IOPS and capacity needs of all the power users.You could position FAS with Atlantis as necessary. We have an FAS based architecture whitepaper in development that should be available very soon!

Total 100K IOPS!Scale testing was done with LoginVSI (industry standard VDI benchmarking tool) and Atlantis Load generation tool that simulates real world VDI, together generating 50 IOPS per desktop.The test results look very impressive50+ IOPS & 30GB per desktop<2ms storage latency >>> which is excellent!No user experience degradation upon one storage controller failure. This was validated by having one storage controller run the 100K IOPS workload for all the 2000 usersAtlantis ILIO offloaded 60% IOPS and capacity dedupe at the host layer so that the 2U EF with 6.7TB usable storage support 2000 users with 30GB per user.Details on the architecture design and performance results are available in the technical whitepaper available today. This architecture should help you beat any competitor in the VDI space.NetApp EF 540 All Flash Arrayw/ 12 x 800GB SSDsTechnical whitepaper available here
87 Results: LoginVSI Heavy (1000 Users) with total 100 IOPS per User Acceptable User ExperienceGoodVeryGoodExcellent3x Faster Response TimeExcellent User ExperienceScales without degrading performanceUserexperienceHere is a VSImax chart from LoginVSI showing the impressive test results for this architecture.On this VSImax chart, the y-axis is the response time in milliseconds that LoginVSI recorded while executing testing operations on the virtual desktop sessions and the x-axis is the number of virtual desktops tested. The VSImax calculation is based on the response times of six operations that run continuously in 48 minute loops for the duration of the test. The operations are intended to simulate generic office worker application activities on a virtual desktop. The six operations are: Starting VSI Notepad, Starting the File Open dialogue, starting the Print dialogue, archive a document with 7-zip with no compression, archive a document with 7-zip with high compression, and starting Microsoft Word with a document. These operations utilize different resources such as virtual desktop CPU (user and kernel), memory, and disk. If such operations continually require a high number of seconds to complete, the user will regard the performance of the virtual desktop as being slow.[click]LoginVSI considers a response time that exceeds 4000 milliseconds (4 seconds) as being non-acceptable. Response time of 3000 milliseconds to 4000 milliseconds is considered Good, 2000 to 3000 as very good, and 1000 to 2000 as excellent. Key highlight for this joint architecture is that the response time is within 1000 to 2000 range, which is excellent.From a storage perspective, the LoginVSI is generating 10 IOPS per desktop. While the LoginVSI test was running, The Atlantis Computing Workbench was used to generate an additional 90 IOPS per user with 65% unique data to simulate and extremely heavy storage load on the system.In this test, the baseline of the system was 1172 ms response time, which is more the 3 times faster than the acceptable user experience. As the load increased to 1,000 users, the LoginVSI Index Average remained consistently in the range with no degradation of user experience as the system scaled. As a result, the LoginVSI Max was not reached, indicating that the joint architecture could scale far beyond the 1,000 users tested even with the additional 90 IOPS generated by the Atlantis Computing Workbench.

93 You have Questions? What Kind of coat can only be put on wet? What jumps when it walks and sits when it stands?I fly, yet I have no wings. I cry, yet I have no eyes. Darkness follows me; lower light I never see?Until I am measured, I am not known. Yet how you miss me, When I have flown! What am I?I run over fields and woods all day. Under the bed at night I sit not alone. My tongue hangs out, up and to the rear, awaiting to be filled in the morning. What am I?What has hands but can not clap?What goes up but never comes down?Two bodies have I, though both joined in one. The more still I stand, the quicker I run. What am I?
