XenServer Best Practice for CVAD Workload


Hi all,


I am looking for documentation about XenServer best practices for Citrix Virtual Apps and Desktops.

By best practices, I mean:

  • Power management options (C-State, BIOS / UEFI Settings, Power Options, ... )
  • Storage recommandations for MCS or PVS write cache
  • Network configuration
  • Dom0 tunning (necessary or not)
  • ...


I have some piece of information with different blog or Citrix documentation but nothing is centralized or some piece of information are for older versions.

Thanks a lot for any help.

I am not sure of a generic guide, but if you have specific asks ,I can help you to the extent I know of.


Storage and Network recommendations depend largely upon the revenue that can be invested to these components , However an SSD backed HBA/FC ( Thick Provisioning) system is expected to give you the best possible performance , if not you can go for an SSD backed NFS storage ( Thin Provisioning ).  Make sure to use multipathing with at least 4 paths and refer to the Vendor's documentation for the best config for multipath.conf


With PVS , the PVS accelerator can be a heavy boost be it boot performance and cost saving ( one of the most widely used features with PVS and XenServer )


Preferably use 10G cards or above for most communications and make sure to use Jumbo Frames for Storage and VM Networking. You can separate out the networks using vLAN.


Start with 8GB for dom0 and as and when you scale up , you can increase the dom0 memory.
