storage unit
The general term that refers to storagesets, single-disk units, and all
other storage devices that are installed in your subsystem and accessed
by the host. A storage unit can be any entity that is capable of storing
data, whether it is a physical device or a group of physical devices.
StorageWorks
A family of modular data storage products that allow customers to
design and configure their own storage subsystems. Components
include power, packaging, cabling, devices, controllers, and software.
Customers can integrate devices and array controllers in StorageWorks
enclosures to form storage subsystems.
StorageWorks systems include integrated SBBs and array controllers to
form storage subsystems. System-level enclosures to house the shelves
and standard mounting devices for SBBs are also included.
stripe
The data divided into blocks and written across two or more member
disks in an array.
striped
mirrorset
See RAID level 0+1.
stripeset
See RAID level 0.
stripe size
The stripe capacity as determined by n–1 times the chunksize, where n
is the number of RAIDset members.
striping
The technique used to divide data into segments, also called chunks.
The segments are striped, or distributed, across members of the
stripeset. This technique helps to distribute hot spots across the array of
physical devices to prevent hot spots and hot disks.
Each stripeset member receives an equal share of the I/O request load,
improving performance.
surviving
controller
The controller in a dual-redundant configuration pair that serves its
companion devices when the companion controller fails.
switch
A method that controls the flow of functions and operations in
software.
synchronous
Pertaining to a method of data transmission which allows each event to
operate in relation to a timing signal. See also asynchronous.
