Figure 1-1. AcceleRAID Disk Array Controllers
Product Description
The Mylex AcceleRAID™ 200 (DAC960PTL-0™) and AcceleRAID™ 250
(DAC960PTL-1™) controllers are I
2
O ready, half-length, PCI to Ultra2
SCSI RAID controllers designed to add RAID capability to SCSI channels
that are resident on a system board. Mylex AcceleRAID controllers supply
the necessary signals that enable SCSI Interrupt Steering Logic (SISL)
hardware to capture and control the embedded SCSI channels(s) on the
system board. This feature implements RAID capabilities on the system
board resident SCSI channels.
The AcceleRAID 200 controller must reside in a PCI slot specifically pre-
configured to support SISL. The AcceleRAID 250 may reside in the
dedicated slot (for a SISL implementation), or in any other PCI slot (to
function as a standard PCI to Ultra2 SCSI RAID controller). System boards
that support the AcceleRAID controllers include the Intel
®
N440BX server
board.
