We have been looking to virtualize our old servers. We currently have 2 quotes that are reasonable but the SANs vary in price. The EMC SAN is much less expensive than the Nimble Storage SAN.
The EMC SAN has 500GB SSD and 12TB disks. The Nimble Storage SAN has 320GB SSD and 12TB disks.
I am told that the Nimble Storage SAN will have more 'usable' space because the snapshots are handled more efficiently.
I do not have any prior experience with SANs and could use a little advice from some experts.
