Dot Hill Systems 200 hot spare or hot, sparing, hot-serviceable, processes are suspended, Iops

hot spare or hot	A drive in a RAID 1 or RAID 5 configuration that is held in reserve to replace any other
sparing	drive that fails. After a reconstruction, the hot-spare drive is returned to the standby status.
hot-serviceable	The ability to remove, replace or add a device while power is still applied but all I/O
	processes are suspended.
hot-swappable	The ability of a field-replaceable unit (FRU) to be removed and replaced while the array
	remains powered on and operational.
ID	Identifier number
IEC	International Electrotechnical Commission
initialization	The process of writing a specific pattern to all data blocks on all drives in a logical drive.
	This process overwrites and destroys existing data on the disks and the logical drive.
	Initialization is required to make the entire logical drive consistent at the onset.
	Initialization ensures that any parity checks performed in the future will execute correctly.
IOPS	Input/output operations per second. A measure of I/O performance, this is usually used to
	quote random I/O performance. See throughput.
JBOD	Just a Bunch Of Disks. JBOD refers to a group of drives without an embedded RAID
	controller; generally, such a group is used without RAID formatting, with a host-based
	hardware RAID controller, or with RAID formatting from host software (with no
	hardware-base RAID controller)
LAN	Local Area Network
LD	Logical drive
logical drive	A section of disk storage space, also referred to as a LUN, that is presented to the host
	operating environment as a single physical drive. A logical drive may be located on one or
	more physical drives. Each array controller can manage one to eight logical drives
LUN	Logical unit number. A LUN is a set of physical drives in a RAID configuration that are
	seen by the operating system as one virtual drive.
LUN mapping	The ability to change the virtual LUN as presented to the server from storage. This enables
	such benefits as the ability of a server to boot from the SAN without requiring of a local
	disk drive. Each server requires LUN 0 to boot.
LUN masking	The characteristic that enables an administrator to dynamically map an HBA to a specified
	LUN. This provides an individual server or multiple servers access to an individual drive
	or to multiple drives, and prohibits unwanted server access to the same drives.
LVD	A low-noise, low-power, and low-amplitude signaling technology that enables data
	communication between a supported server and storage devices. LVD signaling uses two
	wires to drive one signal over copper wire and requires a cable that is no longer than 25
	meters (82 ft.).
MB	Megabyte. 1,000,000 bytes or characters of data.
mirroring: RAID 1	Data written to one disk drive is simultaneously written to another disk drive. If one disk
	fails, the other disk can be used to run the array and reconstruct the failed disk. The
	primary advantage of disk mirroring is 100% data redundancy. Since the disk is mirrored,
	it does not matter if one of the disks fails. Both disks contain the same data at all times and
	either can act as the operational disk. Disk mirroring provides 100% redundancy, but is
	expensive because each drive in the array is duplicated.
MTBDL	Mean time between data loss. In a RAID system, this is the average expected time
	between two rapid disk failures that would cause irreparable data loss.
MTBF	Mean time between failures. A measure of reliability, this is the average expected time
	between failures of equipment, usually measured in operating hours.
MTTR	Mean time to repair. A measure of availability, this is the average time the system is out of
