RAID 5 or RAID 10 (1+0) array for database & public folders
Posted on 2008-06-09
I'm setting up a completely new MS Exchange Server 2003 Standard Edition on a MS Server 2003 OS on a brand new HP Proliant ML350 server. The server has hot-swappable hard-drive bays and a 128 MB battery-backed RAID controller. I have six Western Digital SATA-II RAID Edition 2 hard drives: two of the drives are 160GB and four are 320GB. I've read much here (thanks Sembee and all) about recommended configurations. I know I'll use the two 160 GB drives in a RAID 1 array partitioned into about 30 GB for the OS and the rest for the Exchange app files and transaction logs. My questions:
1. Should I create more than two partitions on the two 160 GB RAID 1 drives to separate the the app files from the transaction logs and perhaps from the page file?
2. For the remaining four 320 GB drives -- which will hold the database files -- should I create a RAID 5 (3 drives plus hot spare) or RAID 10 (2 x 2 drives) array?
3. Should the array of four 320 GB drives be partitioned in any way for any purpose?
Thanks in advance.
