Dell™ commissioned Principled Technologies to compare the performance of the following midrange storage area network (SAN) solutions using a heavily virtualized Exchange 2010 workload:
- Dell EqualLogic™ PS4000XV 14.4TB SAS iSCSI SAN
- HP LeftHand P4500 SAS Virtualization SAN Solution
- FC SAN-2009 Fibre Channel Array
We used the primary storage performance tests in the Microsoft® Exchange Server 2010 Jetstress tool for our comparison. Jetstress reports the input/output operations per second (IOPS) that a given Microsoft Exchange 2010 storage solution provides while maintaining satisfactory responsiveness. Our goal was to determine which SAN solution provided better performance value for transactional applications supporting business operations.
