A $ 30K 56kg machine is 4 servers in one case, each with 2 AMD Opteron 6174 processors. Thus, the highest density is achieved in a 2U case - 96 physical cores and 512GB memory, plus each node has a built-in 40G InfiniBand controller, making it an ideal machine for math calculations and HPC applications. We'll look at how it all works in our article.

In this article, we will tell you about the 4-processor Dell PowerEdge R810 server, which has a complex modular layout that allows you to easily replace a failed block entirely. This server uses FlexMem Bridge technology, thanks to which all the server's memory slots become available to the customer, even if two processors out of four are installed. And, of course, the proprietary iDRAC control system and all those little things that classify such servers as elite.

Dell servers are known primarily for their customers - the largest American corporations, including government organizations, use Dell equipment. And for any customer, the Dell symbol is a sign of excellence in quality control, performance, functionality and service support. This article is a quick guide to the Dell server models available in early 2011.

Servers are the main strong point of Hewlett Packard products. The company owns more than one third of the x86 server market, so it's hard to compete in this regard. The company has expanded its server line this year, and the older models will soon be phased out. We will try to help you figure out the model range of HP servers that is relevant for the coming year.

A budget 2-processor motherboard from Intel is designed for use in office servers of various purposes. It has support for up to 72 GB of memory, PCI Express 8x, 4x slots, as well as a PCI 32 slot. We will test this board in the SC5650DP case on low-end L5520 processors and say how beneficial it is to use two processors against one.

We are testing and comparing two 1U universal rack servers. These servers use 2.5" hard drives, they meet the latest energy efficiency requirements and have the high performance Nehalem architecture. They are very similar, but nevertheless, choose between these two machines carefully, since each has its own characteristics, which we will tell you about.
