Gateway Hardware that connects incompatible networks by providing the necessary
translation for both hardware and software.
Hardwaret
Translative mode Method for achieving address translation. Two hardware translative modes
are available to a QuickLoop enabled switch:
• Standard Translative Mode: Allows public devices to communicate with
private devices across the fabric.
• QuickLoop Mode: Allows private devices to communicate with other
private devices across the fabric.
ISL Interswitch Link. A fiber link between two switches.
Isolated E_Port A port that is online but not operational between switches, due to overlapping
domain ID or nonidentical parameters such as E_D_TOVs.
LIP Loop Initialization Primitive.
L_Port Loop Port.
Multicast Multicast is used when multiple copies of data need to be sent to designated
multiple destinations.
N_Port Node Port. An equipment port connected to the fabric.
NL_Port Node Loop Port. An equipment port connected to the fabric in a loop
configuration using an FL_Port.
PLDA Private Loop Direct Attach.
POST Power On Self Test. A series of self-tests that run each time the unit is booted
or reset.
R_A_TOV Resource Allocation Time-out Value. Used to time out operations that depend
on the maximum possible time that a frame can be delayed in a fabric and
still be delivered. The value of R_A_TOV is adjustable in 1 microsecond
increments over a range from 10 to 120 seconds.
RAID Redundant Array of Independent Disks. Collection of disk drives that appear
as a single volume to the server, and are fault-tolerant through mirroring or
parity checking. See also JBOD.
