The latest vanilla kernel should have support for all of our second generation sas HBAs (6gb/s capable). If there are any problems you can always download an updated driver from the www.lsi.com website.

The Supermicro ftp site you sent is actually for our counterpart in LSI, Megaraid. Since they run a different firmware, they have a different driver in the kernel (megaraid_sas) where as ours are mptlinux (Gen1, 3.0gb/s), mpt2sas (Gen2), mpt2sasbtm (Gen2 but for older 2.6 kernels). We both use the same chip so Supermicro might be making it a little confusing. You might see if they reference the chip as a Megaraid chip in any way or if it is always an LSI chip. It is possible to run it in both modes if all the hardware components are there.

It would probably be best to email Supermicro and get the details from them about the chip to confirm what you need.

Thanks Randy for sending me in the right direction.
Hello linux-scsi and LSI. Any thoughts to the below question would be
much appreciated!
