Facebook is an innovative company in itself, and it's no wonder that they didn't just buy hundreds of servers to run their service. They have improved the memcached caching technology, and now the company's engineers are developing a new type of server that will be optimal for large cloud services - cheap, reliable and efficient. Innovations such as new cabinet heights, dual-input power supplies, lack of remote monitoring systems seem absurd today.

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.

Unique Intel-based 1U server platform that implements new expansion technologies. The motherboard installed in it allows you to divide the existing 32 PCI Express Gen2 lanes in various combinations, and a large selection of risers will make it possible to use cards with PCI-X, PCI-32 and PCI-64 interfaces. RTX technology allows you to use the entire height of the server chassis, and in fact, install any expansion cards of any size - at least two-slot GP-GPU cards.

We are comparing two 2-processor 2U servers from different generations. In addition to the differences in the architecture of the Intel Xeon processors used in them, it is interesting to look at the new technologies used in the 11th generation Dell servers. For example, accelerated deployment and firmware updates, using UIEFI, monitoring from the LCD screen, PCI Express 16x support, TOE, etc. What makes Dell servers so popular around the world.

Today, when choosing a server based on Intel processors, many are wondering whether it is worth overpaying for new items built on the Nehalem architecture, or taking a server of the previous generation, especially with a higher processor frequency. We tested two popular HP Proliant DL380 G5 and G6 server models and compared them not only in speed, but also in design.

The benefits of the new Dell Blades are extended life cycle, lowest power consumption in the industry and support for both existing and future Blades. The new chassis have built-in KVM, and the proprietary iDRAC management system allows you to install the new server faster than ever. Supports up to 8 processor cores per blade, up to 16 blades per chassis.

We continue to introduce you to the new generation of Dell PowerEdge server systems. This time we will consider models of the Pedestal format, which can be installed not only on the floor, but also in a rack. Dell offers a variety of machine modifications that support 2.5 " HDD / SSD & 3.5 & quot; HDD, with a new control system, designed for different tasks and loads.
