We are happy right where we are with the free versions of vSphere 5.1 on a dual-processor 6/12 core X5670 with 12GB RAM RAID-10 2TB VMs are hardware version 7, but the data center is forcing us to go with a dual-processor ES-2690 v4 14/28 core with 64GB and a RAID-10 of at least 2TB. From what I remember, there are at least two issues.
1. 5.1 will refuse to run on any server with more than 32GB.
2. There is an issue with the Windows client as I recall, or it takes both the Windows and web client or...
3. Will going to 4TB or 6TB on the array have any impact?
*I believe the VMs at HW Version 7 will work on 5.1 and 5.5
Basically what issues do I need to watch out for, and what are the trade-offs?
Thanks!
