- Microsemi SCSI driver for PQI controllers.
- Found on newer model HP servers.
- Restrict to AMD64 only as per developer request.
The driver provides support for the new generation of PQI controllers
from Microsemi. This driver is the first SCSI driver to implement the PQI
queuing model and it will replace the aacraid driver for Adaptec Series 9
controllers. HARDWARE Controllers supported by the driver include:
HPE Gen10 Smart Array Controller Family
OEM Controllers based on the Microsemi Chipset.
