Glossary G13
nonredundant controller
configuration
(1) A single controller configuration. (2) A controller configuration that
does not include a second controller.
normal member A mirrorset member that, block-for-block, contains the same data as
other normal members within the mirrorset. Read requests from the
host are always satisfied by normal members.
normalizing Normalizing is a state in which, block-for-block, data written by the
host to a mirrorset member is consistent with the data on other normal
and normalizing members. The normalizing state exists only after a
mirrorset is initialized. Therefore, no customer data is on the mirrorset.
normalizing member A mirrorset member whose contents is the same as all other normal and
normalizing members for data that has been written since the mirrorset
was created or lost cache data was cleared. A normalizing member is
created by a normal member when either all of the normal members fail
or all of the normal members are removed from the mirrorset. See also
copying member.
NVM Non-Volatile Memory. A type of memory where the contents survive
power loss. Also sometimes referred to as NVMEM.
OCP Operator control panel. The control or indicator panel associated with a
device. The OCP is usually mounted on the device and is accessible to
the operator.

controller serving your current CLI session. See also this controller.

parallel data
transmission
A data communication technique in which more than one code element
(for example, bit) of each byte is sent or received simultaneously.
parity A method of checking if binary numbers or characters are correct by
counting the ONE bits. In odd parity, the total number of ONE bits
must be odd; in even parity, the total number of ONE bits must be even.
parity bit A binary digit added to a group of bits that checks to see if errors exist
in the transmission.
