Term
Definition
Btl
Bus-Target-LUN: Identification for a parallel SCSI device
CHAP Challenge-Handshake
Authentication Protocol: If CHAP is enabled, the target
requires the initiator to negotiate CHAP authentication using the CHAP secrets
(passwords). An initiator may reject this negotiation
(passwords). An initiator may reject this negotiation
DP
data port
data port
GbE port used for data movement and inband management
firmware
Software stored in read-only memory (ROM) or programmable ROM (PROM);
firmware is often responsible for the behavior of a system when it is first
switched on

GbE
Gigabit Ethernet
Gigabit Ethernet
A protocol for transferring block-level IO over telnet networks; speed at which
data is passed over Ethernet
data is passed over Ethernet
IETF
Internet Engineering Task Force: The standards body responsible for Internet
standards such as SNMP and telnet through a community of network designers,
operators, vendors and researchers concerned with the evolution and smooth
operation of the Internet

initiator device
A component which originates a command
iSCSI
Internet SCSI (Small Computer System Interface), a protocol to link data storage
facilities over the Internet or an intranet developed by the Internet Engineering
Task Force (IETF); carries SCSI commands over IP networks to facilitate data
transfers over intranets and manage storage over long distances

LED
Light-emitting diode, a type of diode that emits light when current passes through
it; visible LEDs are used as indicator lights on all sorts of electronic devices

LUN
Logical Unit Number: a SCSI identifier of a device
MPn
Management Port
Management Port
GbE port used for management but which may also be used as a data port
Metadata
Information (file marks, directory name information) stored on the tape to assist
data management; content of the metadata is the sole responsibility of the
NDMP Data Management Application

NAS
Network Attached Storage: storage elements connected to a network to provide
file access services to computer systems; an NAS Storage Element includes an
engine to implement the file services and one or more devices to store data;
NAS elements may be attached to any type of network; an NAS host system
uses a file system device driver to access data and NAS systems interpret these
commands to execute the necessary internal file and device I/O operations

NDMP
Network Data Management Protocol: A protocol for data backup and restore
over telnet networks which uses file-based IO
over telnet networks which uses file-based IO
SCSI
Small Computer Systems Interface: a processor-independent standard for
system-level interface between a computer and intelligent devices including hard
disks, floppy disks, CD-ROM, printers, scanners, etc.
