adapter See
BIOS Basic Input Output System (typically in Flash PROM). The program (or utility) that serves as an
interface between the hardware and the operating system and allows booting from the HBA at
startup.
controller A hardware device that facilitates communication between a host and one or more LUNs
organized as an array.
device A target, typically a disk drive. Hardware such as a disk drive, tape drive, printer, or keyboard
that is installed in or connected to a system. In FC, a target device.
DHCP Dynamic Host Configuration Protocol for IPv4. DHCP allows computers to get configuration
information about the network from the network. Addresses are "leased" from servers to clients
for a period of time.
DHCPv6 Dynamic Host Configuration Protocol for IPv6. Although IPv6's stateless address
autoconfiguration removes the primary motivation for DHCP in IPv4, DHCPv6 can still be used
to statefully assign addresses if the network administrator requires more control over
addressing.
DNS Domain Name Server or Domain Name System. A computer program running on a Web
server, translating domain names into IP addresses.
domain ID A number that uniquely identifies a switch in a fabric; the highest or most significant
hierarchical level in the three-level address hierarchy. Generally, each switch is a single
domain. The domain ID is an 8-bit identifier with a range of 0–255. Typically, zero (0) is
reserved and one (1) is the default setting for new switches.
driver The software that interfaces between the file system and a physical data storage device or
network media.
The level structure for Windows XP Professional/2000/Windows Server 2003 drivers is as
follows:

EVA HP StorageWorks Enterprise Virtual Array. A high-performance, high-capacity, and
high-availability storage solution. Each EVA storage system includes a pair of HSV virtualizing
storage controllers and the disk drives they manage.
FDMI Fabric device management interface (FDMI) is a standard enabling the management of devices
such as HBAs through the fabric.
Fibre Channel (FC) A high-speed serial interface technology that supports other higher layer protocols like SCSI
and IP. Standardized under ANSI in 1994.
HBA (host bus The board that interfaces between the host system and the target devices. HBA is synonymous
adapter) with adapter, host adapter, and adapter board.
HBA alias A user-defined name for an HBA.
HBA port A port on the HBA board.
HBA (host bus adapter).
Class Driver. The highest driver level. There is a separate class for disk, Ethernet, and so
forth. This level handles all generic aspects of operations for that class.
Port Driver. The middle driver level, which handles aspects of the operation specific to the
port type; for example, there is a port driver for SCSI.
