ESN Enterprise Storage Network. A storage network implementation that
integrates products, technology, and services offering universal data
access for every major computing platform, operating system, and
application across any combination of SCSI, Ultra SCSI, Fibre
Channel, and ESCON technologies.
Popular protocols for LANs.
EVMd Event management database. Delivers FDMI-related events.
The highest level Fibre Channel mechanism used for communication
between N_Ports. Composed of one or more related sequences, and
can work in one or both directions.
A product that runs on Fabric OS and allows creation of a Fibre
Channel fabric interconnected over distances of up to 100 kilometers.
F
F_BSY Fabric port busy frame. A frame issued by the fabric to indicate that a
frame cannot be delivered because the fabric or destination N_Port is
busy.
F_Port Fabric port. A port that is able to transmit under fabric protocol and
interface over links. Can be used to connect an N_Port to a switch.
See also FL_Port and Fx_Port.
F_RJT Fabric port reject frame. A frame issued by the fabric to indicate that
delivery of a frame is being denied, perhaps because a class is not
supported, there is an invalid header, or no N_Port is available.
Fabric A Fibre Channel network containing two or more switches in
addition to hosts and devices. May also be referred to as a switched
fabric. See also Topology, ESN, and Cascade.
Allows the application to control the fabric directly for functions such
as discovery, access (zoning) management, performance, and switch
control. Consists of a host-based library that interfaces the application
to switches in the fabric over an out-of-band TCP/IP connection or
in-band using an IP-capable host bus adapter (HBA).
One of two possible modes for an L_Port, in which the L_Port is
connected to another port that is not loop capable, using fabric
protocol.
