Even though host bus adapters (HBAs) are integral to effective enterprise data storage, some storage administrators, when they first hear the term HBA, think it's a type of business degree. But they soon realize that they need to be versed in how HBAs work and how HBAs can be used to optimize a SAN infrastructure.

A host bus adapter (HBA) is a circuit board and/or integrated circuit adapter that provides input/output (I/O) processing and physical connectivity between a server and a storage device. Because the HBA relieves the host microprocessor of both data storage and retrieval tasks, it can improve the server's performance time. An HBA and its associated disk subsystems are sometimes referred to as a disk channel…

The HBA transmits data between the host device and the storage system in a SAN and relieves the host microprocessor of the tasks of storing data and retrieving data. The result? Improved server performance.

HBAs are most commonly used in Fibre Channel SAN environments and are also used for connecting SCSI and SATA devices. The emergence of iSCSI has led to the development of another type of host bus adapter, the Ethernet HBA.… [Details]
