Citrix Insight Services Citrix self support tool called CIS, formerly known as Tools-as-a Service (TaaS). Insight Services takes a XenServer status report, and analyses it to determine if there are any operational issues present in the deployment. A best practice is to upload a report after installing a XenServer host to determine if any issues are present which can result in latent performance or stability problems. CIS is used extensively by the Citrix support teams, but doesn't require a commercial support contract for end users link for the tool https://taas.citrix.com/AutoSupport/

There is no difference if you select XenApp or XenDesktop selection while installing, all the features are controlled by license file. so don't worry it makes no difference which option you select when you install. I think citrix should combine into single option

Citrix products progress through three distinct lifecycle phases: Mainstream Maintenance, Extended Maintenance and End of Life. please refer to following link to know the status http://www.citrix.com/support/product-lifecycle/legacy-product-matrix.html? Below is the links of troubleshooting tools available from citrix http://support.citrix.com/article/CTX107572

A  bit of history, Director’s original use case was to be the “daily management console” for XenDesktop.  Back with XenDesktop 5, Desktop Director (as it was previously called) provided real-time information and the ability to troubleshoot and “act” on VDI issues. Hosted App Usage  – Hosted Application Usage reporting provides the analytics and insights to answer who is using what for how long. License monitoring  – Be proactive, know before a license issue impacts your business.  On the Director dashboard, we include alerts for the license issues that may affect your environment.  Alerts such as “operating in supplemental grace period” or “your license is about to expire” are shown. XA 6.5 User Details views  – Expanded capabilities to troubleshoot user sessions for XA 6.5, XA 7.x, XD 5.x, and XD 7.x, all from one tool. Hotfix inventory  – When troubleshooting issues, it is useful to know...

So, what’s new in XenServer 6.5? A lot of good stuff! All 64-bit Massive performance improvements 50% increase in GPU density The return of the popular Workload Balancing (WLB) appliance Numerous usability enhancements So, let’s talk about some of these performance enhancements.  While XenServer has long been known for it’s world-class compute performance, we realized that more and work workloads are now becoming I/O bound.  Thus, the team put massive effort into improving the data path through the networking and storage systems.  Here are some sample benchmarks comparing the performance of XenServer 6.5 vs. XenServer 6.2 (the last major release). Comparison of XS 6.2 to 6.5 performance Who should be interested in XenServer 6.5?  Firstly, anyone who’s using XenServer today will find this a major step up.  Upgrade today and see the difference.  Who else should be interested?  Are you building a cloud?  Xen project is the most popul...

Set these permissions on the root of a profile share to enable it for roaming profile storage. When Windows creates a new roaming profile it acts on behalf of the user, it “impersonates” that user. Therefore we must make sure that on the one hand each user may create new folders while on the other hand ensuring that each user may access only his own profile folder. These permissions apply both to traditional Windows roaming profiles as well as to the user store where Citrix Profile Management keeps its profiles. NTFS permissions: Administrators: full control SYSTEM: full control Authenticated users: list folder/read data & create folders/append data, this folder only Creator/Owner: full control, subfolders and files only Everyone: change Administrators: full control Do not check for user ownership of Roaming Profile Folders in Computer Configuration \ Administrative Templates \ System \ User Profiles Disabling this check speeds up logons slight...

Step 1: to get the list of License run the command by going to the folder of  LS C:\Program Files\Citrix\Licensing\LS>udadmin.exe -list Step 2: run the below commands to release the licenses to delete device licenses for /f "tokens=1,2" %i in ('udadmin -list ^| find /i "_ud"') do @udadmin -f %j -device %i -delete To delete user licenses for /f "tokens=1,2" %i in ('udadmin -list ^| find /i "_ud"') do @udadmin -f %j -user %i -delete

In order to properly design the storage , we must first able to calculate the expected Input/Output Operations per Second (IOPS) requirements. The IOPS calculations must take the following into account: Parameter Description Values Disk Speed The speed that the disk spins has a direct impact on how fast the disk can read the correct sector. 15,000 RPM: 150 Random IOPS 10,000 RPM: 110 Random IOPS 5,400 RPM: 50 Random IOPS Read/Write IOPS are broken down into reads and writes. Certain processes are read intensive while others require more writes. The ratio between reads and writes impacts of the overall IOPS. It has been shown that most desktop implementations result in the follow read/write ratios: Reads: 20% Writes: 80% | RAID Level The RAID configuration impacts how many actual write IOPS are available due to the different types of redundancy in place. The write penalty reduces the overall IOPS for each disk spindle. RAID 0: No RAID Penalty RAID 1: Penalty of 2 ...

When using Provisioning Services with a Windows XP image, despite setting the vDisk to cache to local hard disk, it continues to cache to server. Background This issue could be because of the type of disk used on the image. To use a local disk cache on a virtual machine, it must have the storage attached, available, formatted as NTFS, and must be a basic disk. Resolution Ensure that the vDisk is in basic mode and formatted as NTFS. When the disk is in basic mode and formatted as NTFS, it can cache correctly.

1) Citrix Studio is used instead of Delivery Service Console --> in studio you use to configure enviorement and giving access of apps and desktops to users 2) No IMA datastore concept --> it's doesn't use datastore concept 3) There is no dedicated Zone Master 4) Terminal service is no longer needed 5) sites instead of Farms

Below are some of the differences between Two Versions 1) There is no IMA service which means there is no IMA datastore or Localhost cache 2) There is no support for oracle and access 3) There is no Activity directory configuration wizard or Farm OU 4) Terminal services is not required for XenDesktop 5 as it stores in database 5) Installation wizard is simple in XD5 6) XenDesktop supports only windows 2008, R2 , exit of windows 2003 7) There is no farm concept replaced by sites and group's 8) Idle pool settings is replaced by Desktop Group/Power Mangement
