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.
