1-2 AcceleRAID 150 Installation Guide
Mylex’s AcceleRAID 150 can be used in either one of the following two
situations:
1. A cost-effective, single-channel, standard PCI RAID controller board,
which may reside in any PCI slot (to implement a standard RAID
connection), or
2. A cost-effective PCI RAID controller board with SISL, which must
reside in the prewired, SISL-dedicated slot on a system board (to
implement a SISL connection). See your system board documentation
to identify your board’s specific PCI slot that supports SCSI Interrupt
Steering Logic (SISL).
In addition to the choice of any system board for one of the above situations,
note that some Intel
®
boards also give you the following flexibility:
1. Use the AcceleRAID 150 board plugged into a standard PCI slot as a
single-channel board, or
2. Use the AcceleRAID 150 board plugged into a SISL enhanced PCI
slot. The controller board takes control of the SCSI channels allowing
RAID configurations to be extended from the controller board to the
embedded SCSI channels on the system board.
The following Intel boards: N440BX, T440BX, NA440BX, NC440BX and
SC450NX are examples of the server boards and systems that support the
SISL feature of the AcceleRAID 150 controller.
A specially configured dedicated SISL slot is required to use SCSI Interrupt
Steering Logic (SISL).
Mylex AcceleRAID controllers supply the necessary signals that enable
SISL hardware to capture and control the embedded SCSI channel(s) on the
system board. This feature implements RAID capabilities on the SCSI
channels that reside on the system board.
