I just deployed VMware view 3.1.1 with linked clone technology on my production environment. I haven’t had any issues – it is critical that you carefully review all the best practices and then do pilot deployment to understand user experience before Go-Live.
“Firstly, is there a rule of thumb around how many linked clones you can make from a single parent VM?”
This assumption is not true – VMware recommends 64 virtual machines per replica not per parent VM. Remember each replica is tied to a snapshot- so you can have one Golden Master image with 3 snapshots and create 3 different despot pools each pointing to its own unique replica which interns point to its own unique snapshot. You can have multiple replicas in a single LUN. Just make sure you have enough spindles (underlying physical disks) when you create your lun. Generally, I recommend having more than 4 spindles per LUN. This way you will not experience any bottle necks in the storage I/O subsystem.
“Secondly, to patch VM's that are linked do I simply need to power on the original VM, make the changes, power it off and then make a new snapshot and then modify the desktop pool?”
Yes you are absolutely right about this – just use the recomposition technology to link your desktop pools to the updated snapshot.
