Glossary
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. A
1-Gbps/2-Gbps Fibre Channel port can transmit or receive at nominal rates of 1- or 2-Gbps,
depending on the device to which it is connected. This corresponds to actual bandwidth values
of 106 MB and 212 MB, respectively.
blade A server computer with a modular design optimized to minimize the use of physical space and
energy.
C
CHAP Challenge Handshake Authentication Protocol. A protocol that defines a methodology for
authenticating initiators and targets.
CLI Command Line Interface.
CNA Converged network adapter.
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.
DCB Data center bridging,
DHCP Dynamic Host Configuration Protocol.
DMS Data migration service. A technology that simplifies data migration jobs with minimum downtime
while providing protection against common user errors.
DSM Device Specific Module.
E
EVA Enterprise Virtual Array. The EVA Cluster aggregates multiple EVA subsystems into a single system
image and a single point of management. It allows for the pooling and sharing of storage resources
to improve efficiency, simplify operations, and improve availability over individual storage
subsystems.
F
fabric A fabric consists of cross-connected Fibre Channel devices and switches.
fan-in The number of inputs of an electronic logic gate.
fan-out The number of logic inputs that a given logic output drives.
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. Standardized under ANSI in 1994.
FC-SAN Fibre Channel SAN.
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
