So running my first Citrix XenDesktop 5.5 Deployment, Did the pilot and the design on 5.0 SP1 but when 5.5 came out the first day i saw no reason not to jump straight to 5.5. As i work for a software development company the requirements for developer are quite high so we took some careful consideration when designing the environment as one must when every user us utalising their own Oracle or MS SQL Database plus some JBoss and Eclipse thrown in for good measure.
Long story short we split up the system to a C: and a D: drive for OS and installs respectively, All well and good, nothing in any of the citrix design guides i read saying this wasent possable? XenDesktop just links into VMware and esentially clones the VM right? Wrong! think its best summed up by the one line i got from Citrix support
The Machine Creation Service will always recognise only the first drive, if you require desktops with multiple drives you would work around the MCS by using PVS to stream disks, use partitioning, or manually add disks after MCS has deployed the VM’s.
