QUESTION POSED ON: 16 March 2006
I'm working on an Exchange 2003 migration project. I put a design together for the disk layout, and I'd like to get some feedback.
We are going to cluster two servers together and use an EMC Clariion CX700 for the shared storage. The logical unit numbers have been carved up as follows:
400 GB for SMTP and MTA queues
540 GB for the databases from Storage Group1
40 GB for transaction logs (and I'm going to steal a 500 MB piece for the quorom disk)
Based on your experience, is this an acceptable disk layout? The large logical unit numbers are RAID 1,0 and the 40 GB is RAID 5. I also want to have multiple databases for performance and quicker recovery. So I am considering using that 540 GB logical unit number to house about four databases (three for production and one for recovery).
There are a total of about 2,500 users. Any insight you can give would be great.
