Technical data

Glossary-4
E
E_Port Expansion port. A standard Fibre Channel mechanism that enables switches to network with each other,
creating an ISL. See also ISL.
edge fabric A Fibre Channel fabric connected to an FC router via an EX_Port (where hosts and storage are attached
in a meta-SAN).
EE_Credit End-to-end credit. The number of receive buffers allocated by a recipient port to an originating port.
Used by Class 1 and 2 services to manage frame exchange across the fabric, between source and
destination. See also BB_Credit.
EM Environmental monitor. Monitors FRUs and reports failures.
enabled zone
configuration
The currently enabled configuration of zones. Only one configuration can be enabled at a time. See also
defined zone configuration, zone configuration.
error As it applies to the Fibre Channel industry, a missing or corrupted frame, timeout, loss of
synchronization, or loss of signal (link errors).
Ethernet Popular protocols for LANs.
EX_Port A type of E_Port that connects an FC router to an edge fabric. EX_Ports limit the scope of fabric
services scope but provide device connectivity using FC-NAT.
exchange The highest-level Fibre Channel mechanism used for communication between N_Ports. Composed of
one or more related sequences, it can work in either one or both directions.
F
fabric A collection of Fibre Channel switches and devices, such as hosts and storage. Also referred to as a
“switched fabric.” See also cascade, SAN, topology.
Fabric
Manager
An optionally licensed Brocade software. Fabric Manager is a GUI that allows for fabric-wide
administration and management. Switches can be treated as groups, and actions such as firmware
downloads can be performed simultaneously.
fabric name The unique identifier assigned to a fabric and communicated during login and port discovery.
fabric port
count
The number of ports available for connection by nodes in a fabric.
Fabric Watch An optionally licensed Brocade software. Fabric Watch can be accessed through either the command
line or Advanced Web Tools, and it provides the ability to set thresholds for monitoring fabric
conditions.
failover Describes the Brocade SilkWorm 12000 and 24000 process of one CP passing active status to another
CP. A failover is nondisruptive.
