Glossary

AcceleRAID™

The AcceleRAID family features high performance, cost effective Ultra

SCSI/Ultra2 SCSI LVD and Ultra 160 SCSI to PCI RAID controllers and

adapters for high-end desktops, workstations, and entry level and mid range

servers. AcceleRAID controllers support PCI-based motherboards with

embedded SCSI chips and systems that have a PCI expansion slot designated

for add-in RAID controllers. The AcceleRAID family consists of the 150,

200, 250, 352, 160, 170, and 170LP controllers. The 150, 200, and 250

products can utilize the on-board SCSI chips of servers and use SCSI

interrupt steering logic (SISL). In addition, the 150 and 250 products can

work in any PC or server with a PCI slot whether or not they have SCSI

interrupt steering logic. The 150 and 250 have one Ultra2 SCSI LVD

channel.

Active Termination

A type of terminator used in current SCSI channel setups, which utilizes an

active voltage regulator, thus closely matching cable impedance.

Application Server

A centralized computer that holds and distributes application programs to

users.

ASIC

Application-Specific Integrated Circuit, a chip created for a specific

application.

Array

Multiple disk drives configured to behave as a single, independent disk

drive. See also Disk Array.

Asynchronous Data Transfer

Data transfer not synchronized to a set timing interval. Asynchronous

devices must wait for a signal from the receiving device after each byte of

data.
