In 7.11 and newer, during the Create Catalog wizard, if you select Yes, create a dedicated virtual machine: After you select the master image, there’s a new option for Use full copy for better data recovery and migration support. The Use fast clone option is the older, not recommended, option.
Since these are Full Clones, once they are created, you can do things like Storage v Motion.
Disaster Recovery – for non-persistent VDAs, one option is to replicate the master images to the DR site, and then create a Catalog of machines either before the disaster, or after.
If before the disaster, the VDAs will already be running and ready for connections; however, the master images are maintained separately in each datacenter.
During Disaster Recovery, restore the VM (both disks).
You might have to remove any Custom Attributes on the machine, especially the Xd Config attribute.
Desktop Management in a Citrix environment – Some environments try to use Citrix to improve desktop management.
Here are some desktop management aspects of Citrix that aren’t possible with distributed physical desktops: Persistent virtual desktops – Another method of building VDAs is by creating full clone virtual desktops that are persistent.
Persistent virtual desktops have several disaster recovery options: Create Zones – This section details how to create zones and put resources in those zones.
In 7.9 and older, there’s no way to select a zone when connecting. Instead, Controllers in Satellite zones connect to SQL in Primary zone.
From Mayunk Jain: “I guess we can summarize the guidance from this post as follows: the best practice guidance has been to recommend a datacenter for each continental area. As these numbers show, in those conditions the system can handle 10,000 session launch requests in just under 20 minutes, at a concurrency rate of 36 requests.” If Satellite zone loses connectivity to SQL, then the Connection Leasing feature kicks in.
See Citrix Docs Connection leasing and CTX205169 FAQ: Connection Leasing in Xen App/Xen Desktop 7.6 for information on Connection Leasing limitations (e.g.
Instead, MCS uses it’s identity technology to change the identity of the full clone.
