Re: Storage EMC

See if EMC can support "raid 3" configurations. Raid 3 (others may call it something else) combines the best features of 0+1 (striping for performance) and raid-5 (parity checking) configs without their respective downsides (50% data loss and horrible write performance respectively).

Raid 3 is where you stripe a set of disks (say 5 disks), then have a dedicated hot-swap and a second dedicated parity disk. Great for database installations, if your SAN vendor supports it.
