In order to assist customers in designing their storage layout for Exchange 2007, activewin have put together a calculator that focuses on driving the storage requirements (I/O performance and capacity) and what the optimal LUN layout should be based on a set of input factors.
The calculator uses all the recommendations outlined in the following articles, and thus we recommend you read them before utilizing the calculator:
- Storage Requirements Blog - http://msexchangeteam.com/archive/2007/01/15/432199.aspx
- Processor & Memory Requirements Blog - http://msexchangeteam.com/archive/2006/11/27/431644.aspx
- Understanding Exchange Server 2007 I/O improvements from 64 bit - http://msexchangeteam.com/archive/2006/09/08/428860.aspx
The calculator does not make any recommendations toward storage design (RAID parity, number of disks, etc) as the storage design is largely dependent on the type of storage array being utilized. For more information on some basic requirements around storage design, see the Storage Requirements Blog post listed above.
