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.

A type of terminator used in current SCSI channel setups, which utilizes an 
active voltage regulator, thus closely matching cable impedance.

A centralized computer that holds and distributes application programs to 
users.

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

Multiple disk drives configured to behave as a single, independent disk drive. 
See also Disk Array.

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.
