I'd say run mirrors for all volumes except the data (information store) if your IS size is already large ... but best decision will be based on your current disk usage and projected growth. Depending on your backup schedule and traffic volume, your log files may require large storage too.

I'm looking at this server: http://www.cdw.com/shop/products/default.aspx?EDC=1723415 to be our next Exchange 2010 Enterprise server (currently running 2003 Ent. on 7 year old hardware.) What I'm wondering is, if I wanted to have a separate RAID array for the 1) OS and Exchange 2) Exchange data 3) Exchange logs. then do I need 3 RAID controllers? I've never set up multiple RAID arrays on a server before. Or do I even need to separate them out? Storage is not a big concern, but speed is. Thanks, Evan ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
