Blade servers, x86: Buyer's Guide

Blade servers, x86: Buyer's Guide.

Here we present and try to compare different offers blade- servers from direct producers. In this review, the focus will be on x86- servers.

We begin with an overview of the phenomenon as such blade- server. A recent study by IDC found that the onset of blade segment is largely due to growth in the number of data centers ( data centers ), which is due to the increasing trend towards virtualization. More than two- thirds of the blade- servers located in data centers and server rooms are not in the business, or basements, and 38% of them - are virtualized, which is almost twice the average rate on the market.

... ' IT companies realize that blade- technology can help optimize their IT infrastructure to keep pace with constantly updated requirements of effective business, while simplifying their IT structure that optimizes makes flexible use of assets and a positive effect on energy saving. '.

A recent review of the server market IDC showed that blade servers are very bright and profitable area in the back end of the market. In this segment was 30.9% revenue growth and 8.3% growth in shipments. Under x86 ( 87 percent blade market), ' Blade ' received an impressive 21.4% of all proceeds from the sale of x86- servers.
Not a surprise that there are many blade- products from which to choose. This guide is not complete until the end, but it covers 95 % of the market, if you count in terms of sales.

Blade- I solutions from HP.
IDC put HP in the firm 's leaders race to the blade market with a 50% share of profits. According to Daniel Bowers, manager of HP's blade- segment, the company today predlaget 8 x86- making:.
*. HP ProLiant BL280c G6 Server Blade.
*. HP ProLiant BL2x220c G6 Server Blade.
*. HP ProLiant BL460c G6 Server Blade.
*. HP ProLiant WS460c G6 Workstation Blade.
*. HP ProLiant BL465c G6 Server Blade.
*. HP ProLiant BL490c G6 Server Blade.
*. HP ProLiant BL495c G6 Server Blade.
*. HP ProLiant BL685c G6 Server Blade.

These models cover a range covering the latest series of AMD Opteron and Intel Xeon, and a wide range of input / output devices and methods of network connection. In addition, they integrated Lights Out, and added some redundant functions, built-in RAID- controllers and more. There are also two -and four -processor model.

BL280c, for example, has one or two Xeon 5500/5600 processors. With a starting price of $ 1.509 you get a processor E5502, 2GB memory, two integrated 1GbE network ports and integrated controller SATA RAID ( but not the hard drive). As well as ki for the data center, Bowers said, this model is perfect for small and medium-sized enterprises that want to consolidate all IT business processes, such as file sharing and storage blades in the system at a low price.

A good mid-range model, which uses AMD Opteron, is the BL495c, which is more focused on the use of virtual environments. The starting configuration is a single-processor Opteron 2427, 4GB of memory, built-in dual 10- gigabit Ethernet controller, SATA controller, no hard drive will cost you $ 2.259.
In the high-end segment, HP offers a model for Opteron and Xeon on. BL685c comes with a dual-processor Opteron 8387, 8GB memory, two integrated 10- Gigabit Ethernet network controllers, SATA RAID controller with 512MB cache memory without a hard drive for $ 9289. Bowers (Bowers) recommend this machine for the virtualization, transaction processing and other demanding high load capacity and computational processes.

BL2x220c, on the other hand, with a starting price of $ 9679 has two server nodes, each with two processors Xeon E5530, 24GB of memory, two integrated 1GbE network ports, integrated SATA RAID controller with no hard drive. Bowers believes that this model is ideal for environments Top500 supercomputers in the petroleum sector, scientific computing and animation rendering.
It is necessary to carefully choose the architecture of the choice of blade. Because each vendor has his own scheme of blade system, which means that the blade components from one manufacturer are not compatible with other devices.

Bowyer also recommends the use of blade server using the same components and management tools that are used in the already installed racks. This eliminates the need for new processes, creating a unique inventory of spare parts and debugging of new management tools. Also, you need to pay special attention to the type, density and bandwidth at the installation site. Although the ' blade ', tend to be more energy efficient than traditional rack, still need to consider the possibility of installing new power servers. Some users, for example, in a hurry to buy, new blade- server, but they can not find the energy to run them all. HP BladeSystem Power Sizer is a tool that will help to eliminate such errors.

Now the main thing. Why buy this blade- unit HP? . ' blades ' on the date). Also, keep in mind the fact that the HP BladeSystem is the most widely used platform in the Top500 list of supercomputers. BL2x220c G6 has the highest computational density ( the amount of space per unit of computation ), up to 32 servers in a 10U space. In addition, the ' blade ' G6 include built-in 10Gb network controller. No other supplier of blade systems does not embed 10Gb Controllers.

In the next article, we will continue our review of the review of systems from IBM and the general conclusions on the x86- server products.

Relay: the girls on the streets

He was previously a project - ' Kaliningrad girls '. Quite a popular youth website. I wrote the engine for him. Now he does not already exist, but not the point. The essence of the project was to place photos of local beauties. The boys squealed with delight.

And I thought:. why not look at girls from all over Russia and neighboring countries. To continue the relay is enough to put in his blog picture of the local production of Beauty. I caught this morning in the picture above for a Woman. Ehhh, a figure which. They say that our girls the most beautiful. I think that do not lie. Do you have an opportunity to refute the.

Flexible solar cells

Each silicon fiber itself is an effective high-quality solar cell. Silicon fiber absorbs up to 96% of incident sunlight of a certain frequency and up to 85 % of the collected light.

As seen from this scheme, expensive silicon fibers occupy only a fraction of the volume, the rest is filled with an elastic polymer.

However, Harry Etvater, Professor of Applied Physics and Materials Science, said: ... The most important for solar cell - this is how effectively the absorption of light leads to the creation of the carriers '. Silicon fibers by Etvaterom and his colleagues are able to convert from 90 to 100% of absorbed photons into electrons - technically speaking, the fibers have an almost perfect internal quantum efficiency. ...

Such a high capacity for conversion arises due to the fact that the fibers coated with 2 to 10 % of the solar cell. When light enters the fiber, some of it is absorbed and the rest is scattered. According to Professor Etvatera, it is the interaction between the fibers in the process of scattering of light makes the mesh of fibers as effective in terms of absorption of sunlight, despite the free arrangement of individual fibers.

... - So the original plan was to place the fiber as close to each other. But when we started to count the quality of the absorption, we found that it is possible to capture more light than expected, with the help of a grid of fibers. Having developed the technology for the relatively sparse svetoulavlivaniya nets, we not only achieved an acceptable level of absorption, but also demonstrated an excellent prospect for the future improvement of the efficiency of solar cells using a grid of silicon fibers ...

Each fiber is 30 to 100 microns in length and 1 micron in diameter. ... Since silicon - an expensive component of traditional solar panels, battery, which includes only one fiftieth of the normal amount of this semiconductor may be cheaper to produce. The composite nature of the new solar cell means that it is flexible.

The next step, according to Etvatera will increase the operating voltage and the overall size of the solar cell. ... - Now we are working on solar cells in the area hundreds of square centimeters, that is, the size of a conventional solar cell ...

Etvater reported that scientists have on the way to demonstrate that the solar cells of large size will work just as well as their smaller versions.

The case of Sergei Mavrodi

The founder of the notorious MMM financial pyramid Sergei Mavrodi has recently announced the launch of a new project, where participants promised 20% returns per month, pensioners - 30%. As conceived by Mavrodi, participants will put money in the electronic purse in WebMoney. The organizer of the bubble JSC ' MMM ' Sergei Mavrodi was born August 11, 1955 in Moscow. While still in school Sergei Mavrodi won at the Olympics and different mathematical turn of mind.

In 1978 he graduated from the Faculty of Applied Mathematics, Moscow Institute of Electronic Engineering (MIEM).

After graduation he worked as an engineer, a mathematician at a research institute, since 1980 - Head of Programming. Same time he was illegally while the private manufacture and sale of audio and video.

In 1981 he retired from the Institute and went into business. In order not to be accused of parasitism, was listed in various positions: the latter - a night watchman in the subway.

In 1983 he was arrested for the manufacture of pirated videos, but thanks to the amnesty had served only 10 days.

In 1988 he founded together with his younger brother Vyacheslav Mavrodi, and Olga Melnikova cooperative ' MMM ' ( an abbreviation of the initial letters of the names of the founders ) and its base has created dozens of commercial structures ( JSC ' MMM ', OJSC ' TPA ' MMM ', CJSC ' MMM - .

Until 1991, the cooperative is mainly engaged in trade of computers and office equipment.

Then Sergei Mavrodi, using domestic and international experience, he decided to create a pyramid scheme, investing in high interest rates that made ​​it - up to 1000 % per annum. From that moment began a massive PR- company OJSC ' MMM '. Across the country, were organized items on sales of shares and JSC ticket ' MMM '.

More than three years, Mavrodi built his pyramid. The number of depositors of the company was, according to various estimates, from 10 to 15 million.

The collapse of the JSC ' MMM ' came in the summer of 1994, after the Russian tax authorities and tax police have announced that during his inspection revealed ...

In August 1994, Sergei Mavrodi was arrested on charges of concealing income from the firm he heads JSC ... In October of that year he was released due to changes in preventive measures ( on bail ).

October 30, 1994 Sergey Mavrodi was elected to the State Duma. October 6, 1995 he was elected position was terminated ( Mavrodi has not visited any of the State Duma of the meeting ).

In 1995 he again ran for the Duma from the ' Party of the national capital ', lost the election.

In 1996 it was reopened an investigation of the company ' MMM ' and its leader.

In 1996, Mavrodi was trying to become a candidate for president of Russia. However, the CEC rejected a large part of the signature sheets in support of it and refused to register.

September 22, 1997 the company ' MMM ' was declared bankrupt, and Sergei Mavrodi has disappeared.

In 1998, Mavrodi was put on international wanted list.

Being on the run in early 1998, Sergei Mavrodi along with cousin Oksana Pavlyuchenko has created a new online financial pyramid 'Stock Generation Ltd', is a virtual stock exchange. The site has been non-existent company stock quotes and advice on their purchase. Total exchange lasted about two years. The victims of the pyramid were 275,000 people living in America and Europe.

January 31, 2003 Sergey Mavrodi was arrested in Moscow in a rented apartment on Frunze Embankment. According to documents found in the apartment, Mavrodi was living in Moscow under the name of a Yuri Zaitsev.

He was charged under two articles of the Criminal Code: ...

Damage to ' MMM ' depositors exceeded 110 million rubles. In the case of the victims were found more than 10,000 people across Russia.

The first criminal case against Sergei Mavrodi on tax evasion has been closed due to the lapse of time.

December 2, 2003 Khamovnichesky Court in Moscow found Mavrodi guilty of forgery of the passport and sentenced to 13 months in prison.

April 28, 2007 Chertanovskaya court in Moscow sentenced Sergei Mavrodi to 4.5 years imprisonment to be served in penal colony. As an additional punishment, the court set to recover from Mavrodi a fine of 10 rubles to the state.

In addition, Mavrodi had to pay depositors more than 20 million rubles.

During the investigation and trial entrepreneur left virtually the entire sentence, a court-appointed. He was in custody ' Sailor's Silence ' from January 31, 2003.

Sergei Mavrodi was released after 25 days after the verdict - May 22, 2007.

July 10, 2007 the Moscow City Court considered an appeal against the sentence Mavrodi. In the rehabilitation and dismiss the criminal case the court refused, leaving the verdict in terms of terms of imprisonment, but canceled the fine of 10,000 rubles.

In conclusion, Sergei Mavrodi was engaged in literary work. In early 2008 he published his first book, ' Temptation ', which includes 14 stories. In all, the author of more than 200. In addition, he wrote a novel and several plays. The book was a pilot run of 7000 copies.

In May 2008, Moscow bailiffs have seized on the sale of the first book Mavrodi due to the excitation of enforcement proceedings against him on payment of debts to depositors affected.

In November 2008 the chief bailiff of Russia Nikolay Vinnichenko said that the bailiffs have realized the property of the founder of ' MMM ' Sergei Mavrodi to 18 million rubles and handed out money to depositors, the remaining debt - about 500 million rubles.
