host-side ports
See host ports.
initialization
A process that prepares a storage system for use. Specifically, the system binds controllers
together as an operational pair and establishes preliminary data structures on the disk array.
Initialization also sets up the first disk group, called the default disk group.
K
Kilo. A scientific notation denoting a multiplier of one thousand (1,000).
KB
Kilobyte. A unit of measurement defining either storage or memory capacity.
■ For storage, a KB is a capacity of 1,000 (10
3
) bytes of data.
■ For memory, a KB is a capacity of 1,024 (2
10
) bytes of data.
LUN
Logical Unit Number. A unique identifier used on a SCSI bus to distinguish between
devices that share the same bus. SCSI is a parallel interface that allows up to eight devices
to be connected along a single cable.
management agent
Command View EVA software that controls and monitors the Enterprise Storage System.
The software can exist on more than one management appliance in a fabric. Each
installation of the Command View EVA software is a management agent.
MB
Megabyte. A term defining either:
■ A data transfer rate.
■ A measure of either storage or memory capacity of 1,048,576 (2
20
) bytes.
See also MBps.
MBps
Megabytes per second. A measure of bandwidth or data transfers occurring at a rate of
1,000,000 (10
6
) bytes per second.
Mega
A notation denoting a multiplier of 1 million (1,000,000).
metadata
Information that a controller pair writes on the disk array. This information is used to
control and monitor the array and is not readable by the host.
