SnapServer 7.0 Administrator's Guide
Bar Code
The machine-readable representation of a product code. Bar codes are read by a scanner
that passes over the code and registers the product code. The width of black lines and white
spaces between varies. Combinations of lines and spaces represent characters. Overland
uses 3-of-9 code (Code 39) where each character is represented by 9 bars, 3 of which are
wide.
Bonding
A technology that treats two ports as a single channel, with the network using one IP
address for the server. SnapServers support load balancing and failover bonding modes.
Bridging
Devices that connect and pass packets between two network segments that use different
communications protocol.
Bus or Channel
A common physical path composed of wires or other media, across which signals are sent
from one part of a computer to another. A channel is a means of transferring data between
modules and adapters, or between an adapter and SCSI devices. A channel topology
network consists of a single cable trunk that connects one workstation to the next in a
daisy-chain configuration. All nodes share the same medium, and only one node can
broadcast messages at a time.
CA
Short for Certificate Authority. A trusted third-party in a network that issues and manages
security credentials.
CA Antivirus
The antivirus software bundled with the SnapServer as a SnapExtension.
Cache Flush Array
This is the array that is used to automatically flush cache data in a situation where power
has failed to some of the drives.
Cat 5 Cable
Short for Category 5, it is network cabling that consists of four twisted pairs of copper wire
terminated by 8P8C modular connectors. CAT 5 cabling supports frequencies up to 100
MHz and speeds up to 100 Mbps. (CAT 5e cabling supports frequencies up to 1000 MHz and
speeds up to 1000 Mbps.) It can be used for ATM, token ring, 1000BASE-T, 100BASE-T,
and 10BASE-T networking.
Cat 5 is based on the EIA/TIA 568 Commercial Building Telecommunications Wiring
Standard developed by the Electronics Industries Association as requested by the
Computer Communications Industry Association in 1985.
Cat 6 Cable
Short for Category 6, it is network cabling that consists of four twisted pairs of copper wire
terminated by 8P8C modular connectors made to higher standards that help reduce noise
caused by crosstalk and system noise. The ANSI/TIA-568-B.2-1 specification states the
cable may be made with 22 to 24 AWG gauge wire, so long as the cable meets the specified
testing standards.
