Virtualized Exchange 2010 Performance: Comparing Midrange Dell EqualLogic, HP LeftHand & Fibre Channel SANs
Register to view PDF >

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 14.4 TB serial attached SCSI (SAS) Internet SCSI (iSCSI) storage area network (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.
