PVS Servers are Virtual Machines, running on XenServer 6.0.
The Network Mode is switched back to Bridge-Mode, instead of Open vSwitch.
The Traffic to the Target-Machines / Client Devices stays on the Host.
The Write Cache of those Machines is directed to the local HDD´s of the Host.
The Hosts are 3x HP DL380G7, each equipped with 2x Xeon 2.20 Ghz CPU, 6x 16GB RAM and 8x 15k SAS HDD´s (2x RAID 1 for the XenServer, 6x RAID 0 for the Write Cache and configured as "Fallback-Location" for the vDisk Store if the Connection fails)
The Image and the other VM´s are stored on a D-Link iSCSI Storage with 12x 15k SAS HDD´s and 2x 1GBit NICs used in a Bound.
These VM´s are provided by a single Image and will be used for XenDesktop.
If you have any Questions regarding to the Setup, or how to Design your Environment, feel free to ask :)
