Fibre channel wiring concentrator that collapses loop topology into physical
star topology. Nodes are automatically added when active and removed when
inactive.
Continuous transmission of an ordered set when no data is being transmitted
to maintain an active fibre channel link and synchronization. See also Fill
word.
Initial Identifier. The field in the CT_HDR that displays the port ID of the
client originator of a fibre channel services request.
Server or workstation that initiates communications with storage devices
over a fibre channel network. See also Target.
In Order Delivery. A parameter that, when set, guarantees that frames are
delivered in order if possible, otherwise, frames are dropped.
Initial process associator. An identifier associated with a process at an
N_Port.
Interswitch Link. Fibre channel link from the E_Port of one switch to E_Port
of another.
A port that is online but not operational between switches due to overlapping
domain ID or nonidentical parameters such as E_D_TOVs.
Information Unit. An individual set of information as defined by higher-level
process protocol definition, or upper-level protocol mapping.
Just a Bunch Of Disks. A number of disks connected in a single chassis to
one or more controllers. See also RAID.
Special 10-bit character used to indicate beginning of transmission words
that perform fibre channel control and signaling functions. First seven bits
are comma pattern. See also Comma.
Loop Port. Node or fabric port that can use loop protocol or fabric protocol.
See also Nonparticipating mode, Participating mode.
Time required to transmit a frame, from the time sent until time of arrival.
As applies to fibre channel, a physical connection between two ports,
consisting of both transmit and receive fibres. See also Circuit.
