A properly tuned storage subsystem is key to extracting the highest performance possible from Microsoft Exchange mail servers. Every link in the storage subsystem from the host server to the storage array is a critical point that can allow maximum performance or create a bottleneck that prevents the storage subsystem from reaching its full potential. The Fibre Channel HBA is a critical link between the Exchange Server host system and the storage array. Generally thought of as an interface with performance to spare, differing design and performance characteristics of the current Fibre Channel HBA choices can have an effect on Exchange performance. These HBA performance differences also have a determination on the total cost of the storage solution required to meet the Exchange configuration’s requirements.

Emulex HBAs have long been proven to be a performance leader as demonstrated in a series of performance test reports that can be reviewed at www.emulex.com. The technical attributes that allow superior performance of the Emulex HBAs are also a benefit for Microsoft Exchange deployments. The Emulex performance advantage translates into a lower cost Exchange storage solution for companies and a better quality of service to Exchange mail users.
