SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:

DESCRIPTION
The tws driver provides support for LSI's 3ware 9750 series SATA/SAS con‐
trollers.
These controllers are available in 4, 8, 16 or 24-port configurations,
and support the following RAID levels: 0, 1, 10, 5, 50, 6. The device
nodes for the controllers are of the form /dev/twsX, where X is the con‐
troller number. The driver is implemented as a SCSI SIM under CAM, and,
as such, the logical units that it controls are accessible via the device
nodes, /dev/daY, where Y is the logical unit number.
HARDWARE
The tws driver supports the following SATA RAID controllers:
· LSI's 3ware SAS 9750-4i
