E_port is an expansion port on a switch that is used to connect to
another switch via its E_port.
There are three "basic" types of fibre channel ports; N_port, F_port,
and E_port.
See F_port or N_port for more information.
Static electricity that builds up due to movement. Also, the static
electricity that exists in the air that will discharge on to electronic
equipment.
See electrostatic discharge.
A local area network used for connecting computers, printers,
workstations, terminals, servers and other networking equipment
within the same building or campus. Ethernet operates over twisted
wire and over coaxial cable at speeds up to 10, 100, or 1000 million
bps.
F_ports are fabric ports that connect single devices to the fabric in a
point-to-point topology. F_ports attach to N_ports.
See N_port or E_port.
One or more Fibre Channel switches in a networked topology.
By using a method of remote mirroring, the UltraNet Edge 3000
system ensures that even in the event of a power failure, a disk crash
or a major user error, data isn't lost and the system can keep running.
See Fibre Channel - Arbitrated Loop.
An ANSI standard capable of achieving high speed data transfers
between attached mainframes, workstations, servers, desktop
computers, and storage devices. It is a serial data channel capable of
data transfer rates up to 2 Gigabits per second.
A Fibre Channel application for Storage Area Networks (SANs),
that supports high-speed access to storage arrays over loops as long
as 10 kilometers over a single Fibre Channel link, non-amplified, at
data rates as high as 100 Mbps.Logically, FC-AL operates as a full
duplex, point-to-point, serial data channel. FC-AL is "arbitrated" by
virtue of the fact that access to the storage system is arbitrated on the
basis of level of privilege, with fractional bandwidth supported.
