Servers: IBM is the first place

According to figures published by the Gartner Institute, IBM would have found its place of market leader of the servers in the third quarter of 2011, with a turnover of $ 3.84 billion (3.5%). HP is second hand, its turnover with fell 3.6% to reach $ 3.8 billion. Follow Dell ($1.9 billion, + 6.3%), Oracle and Fujitsu. With a global market estimated to be $ 12.3 billion, IBM has 29.7% share of market, compared to 29.3% for HP, Dell, Oracle 6.2% and 4.7% for Fujitsu 14.5%.

If one is interested in the amounts of servers shipped in the same quarter, is HP who arrives in first place with 2.4 million units (in decreased by 3.1%), or 29.2% of market share. Dell comes second with 21.8% share of market, IBM followed (12.1% market share), Lenovo and Fujitsu. On nontera finally the x 86 architecture -based servers are doing rather well, with an increase of the turnover of 9.3% (+ 7.6% in terms of quantities delivered). By contrast, Itanium and RISC servers saw their sales decline by 6.8%, despite an increase of the turnover of 3.5%.

Google and Facebook should change servers

Google and Facebook should proceed with an update of their servers at the end of the year which will coincide with the release of the Interlagos of AMD and the Romley, the new Sandy Bridge for Intel Server using a Socket LGA 2011. According to DigiTimes, who allegedly received information from manufacturers of servers, this should create a wave of renewal of machines and related products, such as storage or network devices.

Romley will integrate eight cores taking processors support Hyper-Threading and motherboards dual for a maximum of 32 threads. Companies are now restored the economic crisis according to assemblers, which are cited by DigiTimes. Their new economic health explains this desire to update their infrastructure.

Intel showed the first Romley to the IDF in September 2010. They integrate a memory controller channel compatible DDR3 LRDIMM (Load Reduced Dual-Inline Memory Modules) that allows systems using more than 32 GB of memory to turn each bar to its maximum rate. Conventional controllers are unable to maintain the integrity of the data of this type of configuration because of a deterioration of the signal that occurs when using all chip memory. With the LRDIMM, Intel can support 96 GB without loss of frequency.

The LRDIMM uses a buffer which reduces the flow of information between the processor and memory. The bus is therefore less taxed by the increase in the memory modules. The LRDIMM is a derivative of the MetaRAM technology. It allows to virtually consolidate a series of memory chips to simplify the task of the controller and increase the capacity of the bar. For example, it is possible to place 32 125 MB modules for a bar of 4 GB and the system sees that 500 MB 8 chips. It can be more modules on a bar. The problem is that the buffer required for the proper functioning of this technology is expensive, which explains that the LRDIMM are before any reserved for servers.

Rumours that circulated last month the Sandy Bridge Romley will use memory cache L3 2.5 MB per core, for a total of 20 MB, and will have a TDP which will be included between 40 W and 95 W following the requests of the system. They will be coupled with the chipset Intel Patsburg-B. The Romley should be marketed under the name of Xeon E5. They will also have two links QPI, 40 rows PCI-Express 3.0, 4 DMI 2.0.

They will be opposed to the Interlagos of AMD will be built on the Bulldozer architecture. They integrate between twelve and sixteen cores, memory four channels and 16 MB of L3 cache controller. They should be marketed at the same time as the Romley.

Dell and IBM plancheraient chip ARM servers

Dell and IBM, two of the leading manufacturers of servers in the world, ?tudieraient currently the design of unit?s in which fleas bas?es on the ARM architecture would replace processors x 86 employ?s traditionally in this universe. If they get a satisfactory r?sultats, new servers low consumption could make their appearance on the march?.

Paul Prince, in charge of the technological d?veloppement in the business division of Dell, thus indicates site EETimes have test? more than eighteen months the operation of a stack LAMP (Linux, Apache, MySQL and PHP) on a core ARM A8. In other words, a chip similar ? that which ?quipe smartphones pr?sents today on the march?.

Dell reportedly intends to continue its exp?rimentations with the upcoming processors all-in-one (SoC) ARM Cortex A9 that currently produces Marvell, which pr?sentent the int?r?t to embark two hearts of ex?cution. Of its c?t?, IBM not d?voile not its projects in the mati?re, but admits by the interm?diaire of one of its spokesmen that the proposal makes sense, and no pr?senterait no caract?re disruptive r?dhibitoire.

Due to a much less significant computing power, these new entrants would not have vocation ? supplant traditional x 86 processors, but their existence would make sense in applications although sp?cifiques. Among the tracks envisag?es: huge donn?es centres as b?tissent major actors of the Web, in which the multiplication of the machines more important than the power calculation pure and hard.

The universe of servers, which has several d?j? ann?es is int?ressent flea x 86 low consumption such as product VIA, could soon embrace the ARM architecture, confort?s by the multiplicit? of the manufacturers that produce these processors (Marvell, Samsung, TI, etc.).
