RE: DELL PowerVault 220S (RAID) configuration and PERC3/DC
Well, I like the idea of having SEPARATE volumes. Physically separate.

RE: DELL PowerVault 220S (RAID) configuration and PERC3/DC
It depends. How do you plan to use this array? If this array will store the Logs and the Store, then I would configure the logs on a mirrored pair and create a RAID5 array with the remaining files. (This is assuming your are only planning one storage group on this 220s.)

RE: DELL PowerVault 220S (RAID) configuration and PERC3/DC
Transaction logs had been accounted for with a smaller size mirror drives. Our issue is with the quorum disk. OS likes to see it as a separate hard disk... So if one were to configure the RAID volume as large as possible and then use the OS to partition the logical drives, we would not maximize the diskspace. However, if there is not a strong argument against using the RAID BIOS to create the logical drives, we essentially tricked the OS to think that it's a physical drive when it's essentially a logical. I guess to paint a better picture, we have a PowerVault 220S, two 36Gb drives to be mirrored and ten 73Gb drives. From the ten 73Gb set, we like to have three physical drives (from OS standpoint... Don't ask me, it's cluster)... What is the best practice to achieve the most diskspace with f/t intact? -Original Message- From: Dennis Depp [mailto:[EMAIL PROTECTED]] Posted At: Tuesday, September 24, 2002 6:38 AM Posted To: MS Exchange Discussions Conversation: DELL PowerVault 220S (RAID) configuration and PERC3/DC Subject: RE: DELL PowerVault 220S (RAID) configuration and PERC3/DC It depends.
