Hub

A fibre channel wiring concentrator that collapses a loop topology into a physical

 

star topology. Nodes are automatically added to the loop when active and

 

removed when inactive.

Idle

Continuous transmission of an ordered set over a fibre channel link when no data

 

is being transmitted, to keep the link active and maintain bit, byte, and word

 

synchronization.

A server or workstation on a fibre channel network that initiates communications with storage devices. See also Target.

The fabric created by a SilkWorm 6400, consisting of six SilkWorm 2250 switches cabled together and configured to handle traffic as a seamless group.

In-order Delivery; a parameter that, when set, guarantees that frames are either delivered in order or dropped.

Interswitch Link; a fibre channel link from the E_Port of one switch to the E_Port of another. See also E_Port, Cascade.

An E_Port that is online but not operational due to overlapping domain IDs or nonidentical parameters (such as E_D_TOVs). See also E_Port.

Information Unit; a set of information as defined by either upper-level process protocol definition or upper-level protocol mapping.

Just a Bunch Of Disks; indicates a number of disks connected in a single chassis to one or more controllers. See also RAID.

A special 10-bit character used to indicate the beginning of a transmission word that performs fibre channel control and signaling functions. The first seven bits of the character are the comma pattern. See also Comma.

Loop Port; a node port (NL_Port) or fabric port (FL_Port) that has arbitrated loop capabilities. An L_Port can be in one of two modes:

•Fabric mode Connected to a port that is not loop capable, and using fabric protocol.

•Loop mode In an arbitrated loop and using loop protocol. An L_Port in loop mode can also be in participating mode or non-participating mode.

See also Non-participating Mode, Participating Mode.

The period of time required to transmit a frame, from the time it is sent until it arrives.

As applies to fibre channel, a physical connection between two ports, consisting of both transmit and receive fibres. See also Circuit.

A protocol for link-related actions.

Loop Initialization Primitive; the signal used to begin initialization in a loop. Indicates either loop failure or resetting of a node.

Loop Master Time-out Value; the minimum time that the loop master waits for a loop initialization sequence to return.

Loss of signal within a loop for any period of time, or loss of synchronization for longer than the time-out value.

The logical procedure used by an L_Port to discover its environment. Can be used to assign AL_PA addresses, detect loop failure, or reset a node.
