TPC-C, Tpm-C
The Transaction Processing Performance Council (TPC) is a standards
organization that measures transaction throughput of systems. One of their
benchmarks is Tpm-C, which reflects price and performance metrics. TPC-C
reflects new order transaction rate, a benchmark for transaction speed.
Mylex products have won consistently high TPC-C results.
Transfer Rate
The rate at which data moves between the host computer and storage, input,
or output devices, usually expressed as a number of characters per second.
WAN
Wide Area Network, a geographically broader telecommunication structure
as opposed to a local area network (
LAN ) that comprises of two or more
LANs. A wide area network may be composed entirely of private structures,
but the term also seems to connote the inclusion of public networks and all
kinds of transmission media.
Web
A number of computers, servers, or networks linked together in a matrix. See
also
Internet and Intranet .
Write-Back Cache
A caching strategy whereby write operations result in a completion signal
being sent to the host operating system as soon as the cache (not the disk
drive) receives the data to be written. The target disk drive will receive the
data at a more appropriate time in order to increase controller performance.
An optional cache battery backup can be used to protect against data loss as
a result of a power failure or system crash.
