Glossary

SP (storage

processor) A printed-circuit board with processor memory modules and

control logic that manages the storage-system I/O between the

server FC adapter and the disk modules.

SP memory

module A memory mo dule (DIMM ) that provi des the loca l storage fo r an

SP.

SPS (standby power

supply) A unit that provides temp orary backup power in case o f a power

outage. An SPS is required for storage-system write caching. If

power fails, the SPS allows the SP to write the data from its cache

to disk. You can replace an SPS under power, without

interrupting applications. For SPS installation and cabling

information refer to the Standby Power Supply (SPS) Installation

and Maintenance document (See “Related Documentation” on

page xiii.).

storage processor

(SP) See SP (storage processor).

storage-system

caching The procedure of storing disk-based data in RAM memory (in

this case, DIMM memory on an SP) temporarily to save time if

the data needs to be accessed or changed again soon.
