When the Intel Xeon LGA-3647 series processors only appeared, many experts joked that this processor socket is so large that the mini-iTX format Board on it can not be done. And behold ASRock Rack showed the world that anything is possible, and if you need Scalable Xeon Board for nettop - please, the company has for your motherboard EPC621D4I-2M.
Let’s pause and ask ourselves: for what such purposes may be required platform Xeon Scalable in Mini-ITX format? Of course, the first thing that comes to mind is the servers of small depth, designed to accommodate two in one unit of the Cabinet or in short wall cabinets. What’s different is for the most part exotic, and on the rare occasions where network gateways are installed in this way, usually no one even thinks about powerful Intel Scalable processors.
But 10 years ago went fashion for universal Blade-servers, chassis which do not have a common backplane and are a case of Mini-ITX. Of course, such servers were very rare even then, in 2011-2012, but since they are much more convenient and cheaper than traditional Blade-servers, including because of its versatility - you can use the components of any manufacturer. At least, other ideas use Xeon Scalable format Mini-ITX I have no.
Well, let’s look at the motherboard EPC621D4I-2M, which offers the company ASRock Rack. Of course, a large processor socket LGA-3647 forced the manufacturer to save space on everything: instead of the usual DIMM-slots are installed SO-DIMM, and this memory with ECC support is very rare.
