We have a VNX 5700 and we are in the beginning stages of our MBX deployment and wanted to see if anyone else out there is running an EMX VNX and if they recommended RAID Groups or RAID Pools. I reading conflicting information on the subjects and just want to know what is going to be the best for performance. And want to see if anyone out there has any firsthand experience on the matter.

    In some cases, there is a performance benefit to using RAID groups when using high I/O applications. Exchange 2010 is generally not a high I/O application. In order to use most of the advanced features of the VNX, you need to use Pools. Pools are also easier to manage than RAID groups but you lose 2-4% capacity when using Pools versus RAID Groups due to the way the disks are sliced into 1GB chunks. Another thing to consider is that the VNX OE is installed on the first 4 disks and since Pools can only use a full disk, you cannot utilize the free space on the first 4 disk when using Pools but you can with RAID groups. If you do use the free space on the OE disks, it is recommended you don't use them for anthing I/O intensive.

    If you are dedicating this VNX to Exchange 2010, you aren't using any advanced VNX features, you won't be doing much provisioning after the initial setup, and you want to maximize usable space, I would recommend you use RAID groups.
