This driver is new in the Solaris Express 8/05 release and in the Solaris 10 1/06 release.
This release introduces the lsimega driver. The LSI 320-2x card is supported by lsimega with back-end support from LSI. Sun Fire V20z/V40z servers with the optional 320-2x RAID card receive better support for RAID disk I/O and passthrough I/O for SCSI tape and CDROM.
For further information, see the lsimega(7D) man page.
