You don't need three separate raid controllers either. I would separate them out though logically as you have listed. Also, you want to add the battery backed cache to you server as well, as for one it allows you to use other raid options than 0 or 1 (Which HP used to allow for free, but now requires you to purchase a controller upgrade to use 5, 6(adg they call it), or 10). Also, if you have a power issue its nice to have that data committed and not lost with the small potential to corrupt data. They have a few options now, but if you go with Sata drives for the Exchange data store (A totally viable option in EX10) the new flash cache modules for the raid card, really make a nice difference in performance (The 1gb ones we have now really do a nice job). -Greg

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.
