Glossary
A
AMS Attachable Modular Storage
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.
DMS Data migration service. A technology that simplifies data migration jobs with minimum downtime
while providing protection against common user errors.
DRL Dirty region logs.
DSM Device-specific module
E
EUI Extended unique identifier. Part of the numbering spaces, managed by the IEEE, commonly used
for formulating a MAC address.
EVA HP StorageWorks Enterprise Virtual Array
F
fabric A fabric consists of cross-connected FC devices and switches.
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.
FC over Ethernet See FCoE .
FCIP FC over Internet Protocol. An Internet Protocol-level storage networking technology. FCIP
mechanisms enable the transmission of FC information by tunneling data between SAN facilities
over IP networks. This facilitates data sharing over a geographically distributed enterprise.
FCoE FC over Ethernet. An encapsulation of FC frames over Ethernet networks. This allows FC to use
10 Gigabit Ethernet networks while preserving the FC protocol.
Fibre Channel See FC .
FRU Field replaceable unit.
