Path Selection The selection of a transmission path through the fabric. Brocade switches use the FSPF protocol.

Phantom

An AL_PA value that is assigned to an device that is not physically in the loop.

Address

Also known as phantom AL_PA.

Phantom

A device that is not physically in an arbitrated loop but is logically included

Device

through the use of a phantom address.

PLOGI

Port Login; the port-to-port login process by which initiators establish sessions

 

with targets. See also FLOGI.

Point-to-point

A fibre channel topology that employs direct links between each pair of

 

communicating entities. See also Topology.

Port_Name

The unique identifier assigned to a fibre channel port. Communicated during

 

login and port discovery.

POST

Private

NL_Port

Private Device

Private Loop Protocol

Public

NL_Port

Public Device

Power On Self-Test; a series of tests run by a switch after it is turned on.

An NL_Port that communicates only with other private NL_Ports in the same loop and does not log into the fabric.

A device that supports arbitrated loop protocol and can interpret 8-bit addresses, but cannot log into the fabric.

An arbitrated loop that does not include a participating FL_Port.

A defined method and a set of standards for communication.

An NL_Port that logs into the fabric, can function within either a public or a private loop, and can communicate with either private or public NL_Ports.

A device that supports arbitrated loop protocol, can interpret 8-bit addresses, and can log into the fabric.

Public Loop An arbitrated loop that includes a participating FL_Port, and may contain both public and private NL_Ports.

R_A_TOV

RAID

Resource Allocation Time-out Value; the maximum time a frame can be delayed in the fabric and still be delivered. See also E_D_TOV, RR_TOV.

Redundant Array of Independent Disks; a 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.

Request Rate The rate at which requests arrive at a servicing entity. See also Service Rate.

RouteAs applies to a fabric, the communication path between two switches. May also apply to the specific path taken by an individual frame, from source to destination. See also FSPF.

Routing

RR_TOV

The assignment of frames to specific switch ports, according to frame destination.

Resource Recovery Time-out Value; the minimum time a target device in a loop waits after a LIP before logging out a SCSI initiator. See also E_D_TOV, R_A_TOV.

RSCN

SAN

Registered State Change Notification; a switch function that allows notification of fabric changes to be sent from the switch to specified nodes.

Storage Area Network; a network of systems and storage devices that communicate using fibre channel protocols. See also Fabric.
