Glossary
scalable
Refers to how well a system can adapt to increased demands. For example, a scalable network
system could start with just a few nodes but easily expands to thousands of nodes. Scalability is
important because it allows the user to invest in a system with confidence that a business will
not outgrow it. Refers to anything whose size can be changed.
segment
A fabric segments when one or more switches cannot join the fabric because of various reasons.
The switch or switches remain as separate fabrics.
segmented E_Port
Expansion port (E_Port) that has ceased to function as an E_Port within a multiswitch fabric
due to an incompatibility between the fabrics that it joins. See also
serial crossbar assembly
(SBAR) — Responsible for Fibre Channel frame transmission from any director port to any
other director port. Connections are established without software intervention.
serial port
A full-duplex channel that sends and receives data at the same time. It consists of three wires:
two that move data one bit at a time in opposite directions, and a third wire that is a common
signal ground wire.
Session Log
A log recorded at the EFC Manager application that displays a session (login and logout)
history for the EFC Server, including the date and time, user name, and network address of each
session.
SFF
(small form factor) — A type of Fibre Channel connector). See also
shared mode
If a director or switch is in shared mode, all devices on the loop share the 100MB bandwidth
available on the loop. In shared mode, only one end device can communicate with another
device through the fabric loop port (FL_Port) on the director or switch.
Server Platform
A server platform shipped with the product or supplied by the customer for the purpose of
running the HAFM and Element Manager server applications.
simple mail transfer protocol
SMTP. A transmission control protocol/Internet protocol (TCP/IP) protocol that allows the user
to create, send, and receive text messages. SMTP protocols specify how messages are passed
across a link from one system to another. They do not specify how the mail application accepts,
presents, or stores the mail.
