I want to move my Exchange from an older box to a newer box. I have 60 users with about half in remote offices with easy access to Exchange through a subnet.
My new box is an HP Proliant DL180 G6. It came with two 146 GB SAS drives. I'll probably go from Server 2003/Exchange 2003 to Server 2008/Exchange 2008 since I have the software. My current Exchange Information Store totals only about 35 GB. I think the new hardware is more than adequate.
My question is how many more HD should I buy. I'm thinking about 4 more if I buy the SAS 146 GB, but that would cost me about $1200. I've heard I should separate the OS, the logging, and the rest of the Exchange on different hard drives. Although we have done just fine for years with only 3 HD in a RAID. We are pretty small and I don't want to be unnecessarily fancy with this new box, but I certainly want something reliable, stable, and reasonably quick.
Thanks in advance for your help.
