Hi,
We've recently moved to a View 4.6 environment, using linked clones and persistent user data disks (4GB). Currently all is well as I am using local exchange 2007 for email in non-caches mode. However, my organisation is moving to a hosted exchange solution later this year, and it would make sense to use Outlook in cached mode in this environment for performance reasons.
This is a bit of a dilemma as I don't really want ost files on the UDD as I would imagine this will cause heavy I/O on the datastores, plus my initial sizing of the UDD is only 4GB so this would be swallowed up by quite a few of our users' cached mailboxes. I'm also considering (currently testing) trying to move the ost to a network share somewhere else, but this is an unsupported configuration.
So here are my options as I see them
1. Use non-cached mode in the hosted exchange environment. I think this will cause too many unhappy users due to the latency in connecting to our hosted exchange so am trying to avoid this if possible.
2. Used cached mode and keep the ost on the UDD. I'll obviously have to monitor datastore I/O very carefully if I do this, and will probably have to give everyone bigger UDDs.
3. Use re-directed ost files, which as mentioned is unsupported by MS.
What do you guys think? Maybe there is a different solution that I've missed (wouldn't be the first time 
)
Thanks in advance
