I have a VNX 7600, and I am wondering if either/both the compression/deduplication features are actually recommended for use, and if so, how best to optimize for them.

In particular, this array has 38x 200GB SSDs for Fast Cache, and six pools, where each pool contains:

27 x 600GB 10k disks

96 x 2TB NL-SAS disks

What I am considering doing is getting another 30 x 2000GB SSDs and assigning a 4+1R5 of them to each pool, and playing around a bit with thin/compressed/deduped LUNs.

Thoughts?
