David, I told you wrong.. our VNXe unit actually has 21 disk.
Here is what I've done with the RAID 5 4+1 profile you recommended.
ESXi Pool - VMFS Storage (General Purpose) - Disk 0 - 14 (15 Total Disk) Total Space is 9.4 TB
SFSS Pool - Shared Folders (General Purpose) - Disk 15 - 19 (5 Total Disk) Total Space is 3.1 TB
Hot Spare Pool - Disk 20
The EMC VNXe3150 unit I have has 2 storage processors in it, I'm going to have each pool running on a seperate processor hopefully to improve performance.
