Scale-Out Big Data Benchmark: ElasticSearch
ElasticSearch is an open source, full text search engine that can be run on a cluster relatively easy. It's basically like an open source version of Google Search that can be deployed in an enterprise. It should be one of the poster children of scale-out software and is one of the representatives of the so called "Big Data" technologies. Thanks to Kirth Lammens, one of the talented researchers at my lab, we have developed a benchmark that searches through all the Wikipedia content (+/- 40GB). Elasticsearch is – like many Big Data technologies – built on Java (we use the 64-bit server version 1.7.0).
The term "Big data" almost immediately suggests that you need massive machines, more like the new Xeon E7 which supports up to 6 TB. In reality, many big data analyses are running on top of very humble machines in a cluster. ElasticSearch is such an an application: the underlying Java technology does not work well with a larger than 32 GB heap. A total of 64 GB RAM is considered as the sweet spot, to leave some RAM space for filesystem caching.
The result of the Xeon D is stunning. The Xeon D is no less than 70% faster than the fastest Xeon E3s. Better performance is possible with the Xeon E5, but the price tag of those servers is not comparable to the Xeon D servers. The Xeon D-1540 (and as a result the SYS-5028D-TN4T) is the performance per dollar champ here.

Yes, but it's still bad marketing. -D is associated with inferior, overly hot, bad performing Intel chips.IanHagen - Tuesday, June 23, 2015 - link
Certainly. From a marketing standpoint it's a pretty poor choice. I agree with wussupi, E4 would haven been a far better name.karpodiem - Tuesday, June 23, 2015 - link
does anyone know where to buy these online? I'm looking for just the board/processor, model # 'X10SDV-TLN4F'All these random/small Supermicro resellers are selling it now, based on some Google searches. They're marking it up in price by at least a hundred bucks, because availability is limited. Anyone know when Newegg might get it in stock?
Looking to do a FreeNAS build - this board + IBM M1015 card in an ATX motherboard (6x4TB drives in RAIDZ2).

The TLN4F is the one in most demand and almost no place is able to keep it in stock. There are multiple places that will order it for you for ~1K but wait times can be anywhere from 1 week to 1 month.Jon Tseng - Tuesday, June 23, 2015 - link

Dude... You really want to have a look at the latest ThunderX parts or the X-Gene 16nm shrinks before you start making unwise statements like that. These aren't waiting around for A57 they are custom ARM architecture designs. Per core performance might not be as hot as Xeon but once you start to throw 48 cores on a die I wouldn't quite call that "at best competing with Avaton".

X-Gene is in the article, any further shrinks are still entirely vapor. ThunderX isn't currently available is is likely to have significantly worse per core performance than Atom C2k series and worse than A57. All the cores in the world don't do jack if the ST isn't there. And ST performance IS a barrier even in scale out. For general scale out, C2750 was found fairly wanting because of the ST performance, and neither X-Gene nor ThunderX even compete with C2750 in ST performance...

He said "currently". The X-Gene 16nm cores might offer some competition who knows - but those are X-Gene 3 whereas you can't even buy anything with X-Gene 2 28nm ones right now... Likewise, ThunderX servers have been announced, but I haven't seen any reviews yet.name99 - Tuesday, June 23, 2015 - link
Look at the ThunderX parts HOW? Cavium releases fsck-all information about them. No-one knows if they are even OoO, how wide they are, etc.Yes, there are 48 cores on a SoC; and presumably they will do well for tasks like memcached that like lots of low-performance parallelism. But right now, we have ZERO evidence that a ThunderX part is a better single-threaded core than A57, let alone that it's comparable to Broadwell.
