Subject: performance of internal vs san for 7TB
This is my first post/reply. Not sure how this al works:
Best way to confirm acceptable performance would be to use Disk Magic. Short
cut would be to request to have the same number of disk drives (Physical
drives, not LUNs), same speed (15k or 10k) and that they be dedicated
drives, not shared with other hosts. It is also important when they
configure the LUNs to present to the LPARs, that the LUNs are similar in
size and quantity to your physical disk configuration.
We run a Power 7+ with 2 lpars, one is 1.4TB and other is 6.4TB, all
internal disks (19A1 - 236GB).
Our DR provider needs to split that into internal and SAN disk (all at
remote data center). How to confirm performance will be similar (or at least
acceptable)? What to ask and verify? Must confirm acceptable configuration
before annual test.
(switching providers is not an option)
