hello Admins,

I have an Hp SD32 attached to the SAN (XP512) where is running Oracle raw devices configuration.

Each lun is reached by 2 different FC paths (managed by autopath). Each lun is an OPEN-E type, 13.5 GB size (mirrored on the XP box).
The VG is made by 4 luns. The PE is 2 MB and each raw (lvol) is striped on the 4 luns.
Stripes 4, Stripe Size (Kbytes) 256

What about this configuration ? What about Performace ? Any suggestion will be appreciated.

thanx in advance
