HP MPX200 Data Migration Planning Guide

Glossary
A
API Application Programming Interface. A specification intended to be used as an interface by software
components to communicate with each other.
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.
ATIO Accept Target I/O.
B
bandwidth A measure of the volume of data that can be transmitted at a specified transmission rate.
C
CA Controller Adapter.
CDB Command Descriptor Block.
CHAP Challenge Handshake Authentication Protocol. A protocol that defines a methodology for
authenticating initiators and targets.
CLI Command Line Interface. An interface or dialog between the user and a program, or between
two programs, where a line of text (a command line) is passed between the two.
CmdSN Command Sequence Number.
CPG Common Provisioning Group.
CRC Cyclic Redundancy Check. A type of check value designed to catch most transmission errors.
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 that data.
DCBX Data Center Bridging Exchange. A set of enhancements to Ethernet local area networks for use
in data center environments.
DDB Data Description Block.
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.
DMA Direct Memory Access.
DML Data Management LUN.
DMS Data Migration Service.
driver The software that interfaces between the file system and a physical data storage device or network
media.
DSD Data Segment Descriptor.
E
EEPROM Electrically Erasable Programmable Read-Only Memory. Memory that can be erased (entirely,
not selectively) using higher electrical voltages.
ES Enterprise Management
