Target driver for LSI/MPT adapters
Target driver for LSI/MPT adapters was originally developed by Hu Gang, then Erik Habbinga has continued the development.
It supports parallel SCSI (SPI), including Wide SCSI, and Fibre Channel, but also should work with SAS. This driver is on the alpha stage and available for download from the SCST SVN repository. See the download page how to setup access to it.
Recently Theodore Vaida updated it for the latest hardware generation, including 12G support. You can download current version from Github.
