Can anyone tell me the best hard drive order when installing server 2007? for example 1. OS 2. Data 3

What is the best order for the hard drives in the raid, 1. OS 2. Data 3. ? 4.?

I assume that Hard Drive order means you are talking about physical HDDs/LUNs and not partitions. 1: OS RAID-1 2: Exchange Database RAID-10 is preferred over RAID-5. 3: Transaction Logs RAID-10 If you still have HDDs/LUNs then you can separate the DBs and Transaction for each storage group which you are going to host on Exchange 2007.Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

hi,in addition to what Amit has said you can look at planing disk storage for Exchange server;http://technet.microsoft.com/en-us/library/bb124518.aspxand look at the High Availability storage considerations by exchageteam ;http://msexchangeteam.com/archive/2006/10/05/429103.aspxExchange - MVP | www.cozumpark.com | www.mumincicek.com
