NEO 200s/400s User Guide
Domain
A set of network resources in Windows 2000/2003/2008, such as users and groups of users.
A domain may also include multiple servers on the network. To gain access to these
network resources, the user logs into the domain.
Domain Name
The ASCII name that identifies the domain for a group of computers within a network.
Ethernet
The most widely installed LAN technology. 100BASE-T Ethernet provides transmission
speeds of up to 100 Mbps. Fast Ethernet or 1000BASE-T provides transmission speeds up
to 1000 Mbps and is typically used for LAN backbone systems, supporting workstations
with 100BASE-T cards. Gigabit Ethernet (GbE) provides an even higher level of backbone
support at 1000 Mbps (one Gigabit or one billion bits per second).
Ethernet Address
The unique six-digit hexadecimal (0-9, A-F) number that identifies the Ethernet interface.
Ethernet Port
The port on a network card to provide Ethernet access to the computer.
Event
Any significant occurrence or error in the system that may require notifying a system
administrator or adding an entry to a log.
Expansion Slot
Area in a computer that accepts additional input/output boards to increase the capability of
the computer.
F_port
A Fabric port within a Fibre Channel switch that provides a point-to-point link attachment
to a single N_Port. F_Ports are intermediate ports in virtual point-to-point links between
end ports, for example N_Port to F_Port to F_Port to N_Port using a single Fibre Channel
fabric switch.
Failback
Failback occurs when a path with a higher priority than the currently active path is
restored. In this case, I/O will "fail back" to the higher priority path once it is available
again.
Failover
A strategy that enables one Ethernet port to assume the role of another port if the first port
fails. When the port comes back online, the original identities are restored. Failover is
possible only in a multi-Ethernet configuration.
Failover/Failback
A combination of Failover and Failback. When a preferred path becomes unavailable,
another path is used to route I/O until the preferred path is restored. In this case I/O will
"fail back" to the preferred path once it is available again.
