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.
Ultra160 SCSI (Ultra3 SCSI)
The newest in SCSI technology, Ultra160 SCSI increases performance,
reliability, and manageability. With transfer rates of 160 MBps, cyclical
redundancy check, and the capability to automatically test the interface’s
performance level, the Ultra160 SCSI can keep up with fibre channel
technology. Compare with Fast SCSI, Fast/Wide SCSI, Narrow SCSI, Ultra
Wide SCSI, Ultra SCSI (Fast 20 SCSI), Ultra2 SCSI (Fast 40 SCSI), and
Wide SCSI.
Ultra SCSI (Fast 20 SCSI)
A high performance SCSI protocol that has a bus speed of 20 Megabytes per
second in the Narrow SCSI configuration and 40 MB in the Wide SCSI (Fast
20 Wide SCSI) configuration. Compare with Fast SCSI, Fast/Wide SCSI,
Narrow SCSI, Ultra Wide SCSI, Ultra2 SCSI (Fast 40 SCSI), Ultra160 SCSI
(Ultra3 SCSI), and Wide SCSI.
Ultra Wide SCSI
16-bit wide Ultra SCSI, double the speed of narrow SCSI. Compare with
Fast SCSI, Fast/Wide SCSI, Ultra SCSI, Ultra2 SCSI, and Ultra160 SCSI
(Ultra3 SCSI), and Wide SCSI.
Ultra2 SCSI (Fast 40 SCSI)
A higher performance SCSI protocol than Ultra SCSI. Ultra2 SCSI has a bus
speed of 40 Megabytes per second in the Narrow SCSI configuration and 80
