Product Description
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, which
may reside in any PCI slot (to implement a standard RAID connection),
or
2. A cost-effective PCI RAID controller 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 controller plugged into a standard PCI slot as
a single-channel controller, or
2. Use the AcceleRAID 150 controller plugged into a SISL enhanced PCI
slot. The controller takes control of the SCSI channels allowing RAID
configurations to be extended from the controller 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.
