Strong server board, but has limitations 09/30/2012
This review is from: SUPERMICRO MBD-X8SI6-F-O ATX Server Motherboard LGA 1156 Intel 3420 DDR3 1333
Supermicro quality. This board, like most of the server boards, has exceptional reliability and build quality.
Integrated LSI2008 (actually a MegaRAID SAS 9240-8i) is a 6GB/s SAS RAID controller (which you can flash to JBOD if you like). It's compatible with HP SAS 6GB/s expanders, so if you need to run 16, 24, etc. disks - this is for you.
The 9240-8i is limited to RAID-0, RAID-1, and RAID-10. (Newegg's listing claims RAID5 in Windows, I never loaded Windows on the box, so I can't speak to that). ESX is troublesome on this board because of the HBA (more on that below). I ran Linux with the HBA flashed to JBOD mode, and used mdadm to manage a 24-disk RAID6 array. This worked well, especially since I used an expansion card for LAN (again, see below).
The Intel 82574L uses the e1000e driver under Linux and ESX. Sadly, this driver is badly flawed in several versions of ESX (and probably other systems), and can cause system lockup under heavy load. For ESX or Linux applications, better to find a LAN chipset that will use the igb driver instead.
This is a great board, and the RAID HBA isn't something you'd expect to see on a uniprocessor server board. But it's not without flaws and limitations. Because of the limitations of the HBA and the LAN chipset, I have migrated my ESX VMs to the excellent X9DRH-7F board (LSI 2208 HBA and Intel I350 LAN)
