HBAs and Network Storage Interfaces
While it is true that storing and connecting functions are independent, there obviously has to be some sort of connecting interface that storage data passes through on its way between systems and storage. The connecting interface for SANs is a network adapter. Storage adapters in host systems are usually HBAs. This section discusses the use of HBAs as SCSI initiators, the qualification process for HBAs within the industry, the use of multiple HBAs in systems, and adapters used in devices and subsystems.
NOTE
An interesting marketing problem is brewing with product naming due to the emergence of iSCSI. There are a few approaches to implementing a network adapter for iSCSI, including the ability to use an off-the-shelf ...
