An arbitrated loop attached to a switch.
Can indicate either the product that allows private devices within loops to
communicate over the fabric with other devices, or the set of actual devices
or looplets connected in a loop by QuickLoop technology. All devices in a
QuickLoop share a single AL_PA space and behave as if they are in one loop.
Resource Allocation Time-out Value. Maximum time a frame can be delayed
in the fabric and still be delivered. See also E_D_TOV.
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.
Product that enables two switches to connect over an ATM connection.
Requires compatible fibre channel-to-ATM gateways. Can be up to 10
kilometers distance between each switch and respective gateway.
The rate at which requests arrive at a servicing entity. See also Service Rate.
As applies to fabric, a communication path between two switches.Routing
is the assignment of Class 2 or 3 frames to the most appropriate switch ports
for the intended destinations. See also FSPF.
Resource Recovery Timeout Value. The minimum time a target device in a
private loop must wait after a LIP before logging out a SCSI initiator. See
also E_D_TOV, R_A_TOV.
Registered State Change Notification. Switch function that sends notification
of fabric changes from the switch to specified nodes.
Storage Area Network. Network of systems and storage devices that usually
communicate using fibre channel protocols. See also Fabric.
A fibre channel structure containing one or more frames transmitted in a
unidirectional manner between N_Ports. See also Exchange, Frame.
The rate at which an entity can service requests. See also Request Rate.
Sequence Initiative.
Fibre-optic cabling standard that provides for distances of up to 10 kilometers
between devices.
