Glossary
management and increase storage from 2 gigabyte to 6 terabytes. The
architecture was enhanced with the introduction of ESA/390 in 1990.
Enterprise Systems
Connection
An IBM architecture, technology, and set of products and services
introducedin1990 thatprovides adynamically-connected computing
environment using fiber-optic cables as the data transmission
medium. See also Fibre Connection.
E_Port See expansion port.
error-detect time-out
value
The user-configured minimum time that a director or switch port
waits for Fibre Channel sequence completion before declaring an
error and initiating the recovery process.
ESA See Enterprise Systems Architecture.
ESCON See Enterprise Systems Connection.
ESD See electrostatic discharge.
Ethernet A widely-implemented 10 or 100-Mbps LAN protocol that uses a bus
or star topology based on the IEEE 802.3 standard. The protocol
provides carrier-sense multiple access, and resolves signal contention
using collision detection and transmission.
event code A three-digit number that identifies an event that occurred at a
director, switch, or the management server. Event codes provide
general system information or failure information. Fault isolation for
McDATA products is event code driven.
Event Log A log recorded at the Element Manager application that displays a
history of director or switch events, such as degraded operation, FRU
failures,FRU removals and replacements, andlink incidents. Contrast
with EFC Event Log.
expansion port In Fibre Channel protocol, a director or fabric switch port that
connects to another director or switch E_Port to form an ISL. See also
bridge port.
