H
HBA
Host Bus Adapter. A circuit board and/or integrated circuit adapter
installed in a workstation or server that provides input/output
processing and physical connectivity between a server and a storage
device. An iSCSI HBA implements the iSCSI and TCP/IP protocols in a
combination of a software storage driver and hardware.
HDD
Hard disk drive.
I

A system component that originates an I/O command over an I/O bus
or network, such as an I/O adapters or network interface cards.

IP address
An identifier for a computer or device on a TCP/IP network. Networks
using the TCP/IP protocol route messages based on the IP address of
the destination. The format of an IP address is a 32-bit numeric
address written as four numbers separated by periods. Each number
can be zero to 255 (for example, 192.168.0.200). The current main
address is IPv4 (Internet Protocol Address Version 4) and the next-
generation address is IPv6 (Internet Protocol address Version 6).
IP-SAN
Block-level Storage Area Networks over TCP/IP using the iSCSI
protocol.
iSCSI
Internet SCSI. An IP-based standard for connecting data storage
devices over a network and transferring data using SCSI commands
over IP networks. iSCSI enables a Storage Area Network to be
deployed in a Local Area Network.
