The
ciss driver provides support for the CISS interface implemented by fifth and later generations of the HP/Compaq Smart ARRAY family of controllers.
The CISS interface is defined in the document entitled
CISS Command Interface for SCSI-3 Support Open Specification, Version 1.04, Valence Number 1, Compaq Computer Corporation, 2000/11/27.
This driver supports several Compaq and HP controllers implementing the CISS interface, including:
•
Compaq Smart Array 5300 version 1
•
Compaq Smart Array 5300 version 2
•
Compaq Smart Array 5i version 1
•
Compaq Smart Array 5i version 2
•
HP Smart Array 1 through 13
These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.
Although the controllers are actual RAID controllers, the
ciss driver makes them look just like SCSI controllers. All RAID configuration must be done through the controllers' BIOSes.
Hardware from previous generations of this product family may be supported by the
cac(4) driver.
