Host Bus Adapter. An adapter allowing input and output of data between the RAID and the host system. Fibre channel units, in particular, ofter require specialized HBAs to interface with RAIDs, while SCSI can be considered a more general HBA.
Host bus adapter. A PCI adapter card which resides in the server whose only function is to convert data commands from PCI-bus format to storage interconnect format (examples: SCSI, Fiber Channel) and communicate directly with disk drives, tape drives, CD-ROMS, or other storage devices.
Host Bus Adapter. The HBA relieves the host microprocessor of data storage and retrieval tasks, usually improving the computer's performance time. An HBA and its disk subsystems make up a disk channel.
Host Bus Adapter An HBA is an I/O adapter that sits between the host computers bus and the Fibre Channel loop and manages the transfer of information between the two channels. In order to minimize the impact on host processor performance, the host bus adapter performs many low-level interface functions automatically or with minimal processor involvement.
HBA stands for Host Bus Adaptor. It is the part in an external network that constitutes the interface between the network itself and the PCI bus of the compute node. HBAs usually carry a good amount of processing intelligence themselves for initiating communication, buffering, checking for correctness, etc. HBAs tend to have different names in different networks: HCA or TCA for Infiniband, LANai for Myrinet, ELAN for QsNet, etc.
Host bus adapter. A hardware device that "connects" the operating system and a SCSI bus. A SCSI miniport driver manages the lower layers of the SCSI-II protocol on the HBA. See miniport driver. See also port driver, class driver, SFD, and SCSI.
HEALTH BENEFITS ADVISOR. An individual at a Military Treatment Facility who is responsible for providing information about the Uniformed Services Health Benefits Program, and who assists beneficiaries to obtain healthcare benefits.
Health Benefits Advisor. Health Benefits Advisors (HBA) are military personnel stationed at Military Treatment Facilities (MTF) who can assist you with on base appointments, Non-availability Statements (NAS) and understanding your benefits. The HBA has been renamed Beneficiary Counseling Assistance Coordinator (BCAC).
