PCIe glossary

HBA

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.
