Hi Supermicro, I'm looking for information on whether the LSI 2108 is fully supported in the vanilla linux kernel, and any thoughts as to the quality/ robustness of the driver. The servers in question that I'm interested in are the: http://www.supermicro.com/products/system/2U/8026/SYS-8026B-6R.cfm?SAS=Y Thank you for your time, feel free to see the below history for some background.

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. > > -----Original Message----- > From: James Shubin [mailto:purpleidea@xxxxxxxxx] > Sent: Thursday, January 20, 2011 5:57 PM > To: Randy Dunlap > Cc: scsi; linux-kernel@xxxxxxxxxxxxxxx; DL-MPT Fusion Linux > Subject: Re: Status of the LSI 2108 > > Thanks Randy for sending me in the right direction. > Hello linux-scsi and LSI.
