mirrored
write-back
caching
A method of caching data that maintains two copies of the cached data.
The copy is available if either cache module fails.
mirrorset See RAID level 1.
MIST Module Integrity Self-Test.
multibus
failover
Allows the host to control the failover process by moving the units
from one controller to another.
N_port A port attached to a node for use with point-to-point topology or fabric
topology.
NL_port A port attached to a node for use in all topologies.
network In data communication, a configuration in which two or more terminals
or devices are connected to enable information transfer.
node In data communications, the point at which one or more functional
units connect transmission lines.
Non-L_Port A Node of Fabric port that is not capable of performing the Arbitrated
Loop functions and protocols. N_Ports and F_Ports loop-capable ports.
non-
participating
mode
A mode within an L_Port that inhibits the port from participating in
loop activities. L_Ports in this mode continue to retransmit received
transmission words but are not permitted to arbitrate or originate
frames. An L_Port in non-participating mode may or may not have an
AL_PA. See also participating mode.
nominal
membership
The desired number of mirrorset members when the mirrorset is fully
populated with active devices. If a member is removed from a
mirrorset, the actual number of members may fall below the “nominal”
membership.
node In data communications, the point at which one or more functional
units connect transmission lines. In Fibre Channel, a device that has at
least one N_Port or NL_Port.
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.
