A

array

A storage system that contains multiple disk or tape drives. A disk array, for example, is
differentiated from a disk enclosure, in that the array has cache memory and advanced
functionality, like RAID and virtualization. Components of a typical disk array include disk array
controllers, cache memories, disk enclosures, and power supplies.

B

bandwidth

A measure of the volume of data that can be transmitted at a specified transmission rate.

C

CHAP

Challenge Handshake Authentication Protocol. A protocol that defines a methodology for
authenticating initiators and targets.

CSV

Comma-separated value. A data file used for storage of data structured in a table form.

D

data migration

The process of transferring data between storage types, formats, or computer systems. Data
migration is usually performed programmatically to achieve an automated migration, freeing up
human resources from tedious tasks. Migration is a necessary action for retaining the integrity of
the data and for allowing users to search, retrieve, and make use of data in the face of constantly
changing technology.

DHCP

Dynamic Host Configuration Protocol.

DML

Data management LUN.

DRL

Dirty region logs.

E

EUI

Extended unique identifier. Part of the numbering spaces, managed by the IEEE, commonly used
for formulating a MAC address.

F

fabric

FC

Fibre Channel. High-speed serial interface technology that supports other higher layer protocols
such as SCSI and IP, and is primarily used in SANs.

FCIP

Fibre Channel over Internet Protocol. An Internet Protocol-level storage networking technology.
FCIP mechanisms enable the transmission of Fibre Channel information by tunneling data between
SAN facilities over IP networks. This facilitates data sharing over a geographically distributed
enterprise.

FCoE

Fibre Channel over Ethernet. An encapsulation of Fibre Channel frames over Ethernet networks.
This allows Fibre Channel to use 10 Gigabit Ethernet networks while preserving the Fibre Channel
protocol.
