RE: EMC DMX & DW

I agree. It's a big data warehouse (4TB) and I'm not happy switching from raid 0+1 to raid-5.

I'd be really surprised if you couldn't order it (or configure it) as Raid 1 instead. I don't have a DMX here, but typically configure everything as 0+1 (mirrored & striped) for our ERP applications.

Others I've spoken to have fallen in love with the DMX, which supports snapshots; instead of an equal amount of disk to support BCV's, you now only need 10-15% to take an instantaneous "snapshot" of your data.
