We have just added a new disk group of 10 X 450Gb drives to our EVA, set with a Failure protection of 1. Occupancy is 0 at this point (no Vdisks created).
When I select the disk group I am seing a total capacity of only 3350Gb. I understand the need for rebuild space etc but this seems excessive.

Does anyone have a good explanation of why so little space is available for use?

Hmm, you're right raj27962, it's only 2 disks worth for single sparing right up to 48 disks in the group, I thought it was like the one per 8 of vRAID5.
