ASRock Rack has been releasing several small form factor LGA2011 motherboards lately, including the just released ASRock Rack EPC612D4U-2T8R. This is perhaps one of the most intriguing mATX form factor boards we have ever seen. The motherboard packs a huge number of features into an extremely small package (given the functionality).
ASRock Rack EPC612D4U-2T8R Quick Overview
Like the ASRock Rack EPC612D4I we just reviewed the ASRock Rack EPC612D4U-2T8R has a single narrow ILM LGA2011-3 socket. That supports one Xeon E5 processor in the mATX form factor. There are four DIMM slots, however one can use DDR4 RDIMMs making it similar to a Xeon D platform in terms of memory. 64GB should be inexpensive to attain while 128GB is more expensive but easy to hit on this platform.
Perhaps the most interesting side though is the expansion possibilities. The ASRock Rack EPC612D4U-2T8R has an Intel X540 dual 10Gbase-T controller and a LSI/ Avago SAS3008 8-port 12gbps SAS controller built-in. It also has 8x Intel C612 PCH based SATA ports for a total of sixteen storage ports availiable.
Beyond the onbaord I/O there are three PCIe slots. Two of which are PCIe 3.0 x16 and one is a PCIe 3.0 x8. For those counting, that means there are 40x PCIe lanes available via slots and one would assume at least 12 lanes between the SAS3008 and X540. Hopefully we will get a review unit to see how ASRock is managing the PCIe lanes since there are only 40x PCIe 3.0 lanes available off of the CPU.
For those looking at single socket platforms, 2015 has been a banner year between the small form factor Xeon E5 platforms ASRock Rack has been producing, the Xeon D, and what we will see soon on the lower end Xeon E3 and C2000 lineups later this year.
