No, that LCR functionality was pulled. 1 DB copy per server max.

Here's what MS says (italics mine): "RAID (Redundant Array of Independent Disks) is often used to both improve the performance characteristics of individual disks (by striping data across several disks) as well as to provide protection from individual disk failures. With the advancements in Exchange 2010 high availability, RAID is no longer a required component for Exchange 2010 storage design. However, RAID is still an essential piece to Exchange 2010 storage design for stand-alone servers as well as high availability solutions which require either additional performance or greater storage reliability. The table below provides guidance for the common RAID types that can be used with the Exchange 2010 Mailbox server." http://technet.microsoft.com/en-us/library/ee832792.aspx Further reading suggests a single server could maintain multiple copies of the Exchange database on a single server's JBODs, but that's got to be more overhead than just RAID 1'ing it.

Dumb question. if I use RAID 1 on the OS and log volumes, and it's not recommended that I use RAID 5 for the data, what *should* I use for the data? Thanks J Evan From: Erik Goldoff [mailto:[email protected]] Sent: Wednesday, March 03, 2010 7:31 PM To: NT System Admin Issues Subject: RE: Disk configuration in new server 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.
