H
HBA (host bus adapter)
An HBA is the critical link between a host server or workstation
and a storage subsystem, integrating computing platforms, OSs,
and I/O protocols to ensure proper interoperability and
functionality. The HBA provides direct storage connectivity from
the system to data within the storage subsystem and enables
stable, high-speed transmission of information and files. HBAs
manage the controller-specific aspects of handling a storage driver
interface device implemented as a target driver, which supports
mass storage peripheral devices such as disks drives and tapes. A
storage driver interface is used to implement SCSI and other
storage device drivers. An HBA connects to the storage subsystem
to the host computer and uses either fiber or copper media.
hot-swapping
Removing a component from a system and installing a new
component while the power is on, the system is running, and
without pausing I/O.
I
initiator
An initiator (host system) sends operation requests to be
performed by a target device (peripheral). See also target.
J
JBOD
Just a Bunch of Disks. See volume set.
K
kill
When a storage system is in active-active mode, one controller can
kill the other controller by resetting it and taking it offline. See also
