[Lustre-discuss] Disk array setup opinions

I am currently having a debate about the best way to carve up Dell MD3200's to be used as OST's in a Lustre file system and I invite this community to weigh in...

I am of the opinion that it should be setup as multiple raid groups each having a single LUN, with each raid group representing an OST, while my colleague feels that it should be setup as a single raid group across the whole array with multiple LUNS, with each LUN representing an OST.

Does anyone in this group have an opinion (one way or another)?
