Predicted in 2012 Energy-conserving server or turning to ARM framework
In 2012, when a lot of enterprises hope to reduce the cost of data centre and use ARM processor and figure chip instead, a fundamental change will happen in the server framework.
The analysts think, the low consumption processor that companies such as ARM,etc. produced will be used widely in the data centre of enterprises in 2013, if complemented with the chip of the figure again, not only performance will be promoted by a wide margin, and the consumption will be reduced by a wide margin. A lot of experiments of adopting ARM chip on the server have been in process for a long time, the figure chip has already been used in some fastest supercomputers in the world too.
The analysts think, the customer is while developing and adopting in order to lower costs, while purchasing the server, energy-conservation becomes one of primary decisive factors. This year, around calculating super large-scaly, a wave of upsurge of constructing cloud server and high-performance server has appeared, and because of the requirement for large-scale performance, the energy consumption of these servers is very surprising. For save energy, get rid of some enterprise to will consider, use low ARM processor of consumption future, this kind of processor is used mainly in dull and stereotyped computer and intellectual mobile phone at present.
Try ARM framework
The research manager Jed Scaramella of IDC claims, ” many customers are testing all kinds of technology, they hope to obtain higher energy efficiency. ” Some enterprises begin to pay close attention to U.S. dollar / tile or U.S. dollar / indexes such as square foot,etc., and begin to pay close attention to the performance / tile index of the server.
The growth that the cloud calculates is promoting the scale of the server partially too, a lot of enterprises are constructing publicly-owned cloud and privately owned cloud. In a lot of pairs of trough x86 servers are all disposed by the cloud used in super large-scale calculation. This kind of server is used mainly in application such as data analysis and commercial intelligence.
Adopt the substitute that the high density server of ARM processor probably becomes x86 server over the next several years, because IT managers of enterprises should consider calculating the density, as well as consider the low consumption demand. Analyst claim whom low the intersection of consumption and ARM punish get together, may offer than traditional the intersection of x86 and the intersection of server and chip, if Intel calculates handling capacity to strong or AMD white dragon more energy-conserving cloud. However, the chip group based on ARM processor is dealing with the intensive task of the data, for example when database and ERP,etc. are employed, will lag behind x86.
This year, some companies have already begun to try out the server of ARM processor. For example Hewlett-Packard released one to adopt server of Calxeda chip to be designed last month, the core of this chip is one and 4 nuclear ARM processors, the consumption has 1.5 watts only. Nvidia declared too last month, a super computer system adopted its Tegra 3 chip to construct in Barcelona, and Tegra 3 is even if one 4 nuclear ARM CPU, Tegra 3 is still furnished with the independent figure processor, can improve the speeds of science and mathematical measurement.
“We have already seen ARM street maps and products of some companies this year. But this does not mean it will become the mainstream next year, ” Scaramella says.
The chief analyst Dan Olds of Gabriel information group says, breaks through the traditional server system framework to estimate that will see soon with ARM processor, but its influence can be felt at the beginning of 2013. Olds points out, nearly all main server manufacturers will begin the test ARM processor.
” if Hewlett-Packard really plans to try ARM framework, then ARM may be hopeful, ” Olds says.
Prospect of ARM framework
The existing ARM processor can only support 32 to seek the location, the error-correcting function is very limited too. 64 computers can seek memory and memory address of the larger quantity in the location, it is very useful and this intensive to data should use. The end of October this year, ARM has introduced one’s own 64 first microprocessor frameworks ARMv8, the goal obviously lies in keeping expanding until the advanced server from the sensor the applicable scope of its processor.
ARM processor and coupling of the figure processor are very attractive, Olds says. Existing a lot fastest supercomputers in the world are all using the processor of the figure, while operating some application, the chip of the figure is higher than the performance of traditional CPU.
“Such an association can offer each watt higher density, higher computing capability, the cost is lower too at the same time, ” Olds says.
It have since high performance nowadays figure processor it calculate to in that ends low permeate for trend, the high performance used in the energy, pharmacy, financial service, media and other trades more and more is calculated.
But the analysts think unanimously, because there are a great deal of problems in hardware and software, so will switch over from x86 until ARM framework will be a great challenge. In fact, when a lot of servers are bought to select, for example truss up server, storing, operating load of the network equipment and software and optimize the system, the customers have already felt that it is very difficult to make decision. It may be breakthrough to switch over to ARM framework, will bring many advantages, but it disposes or needs time.
“This kind of switch must be a progressive course, can not happen overnight, “Scaramella of IDC says.
CIO Gerry McCartney of Purdue University agrees with this view too, says their university puts the existing IT infrastructure into enormously, it is for the most part x86 server, mostly collected writing for x86 order too in procedure code that researchers used.
” researchers do not want to change the software, ” McCartney says. He has made efforts many years ago, had planned to switch over from x86 to another system framework, but the result succeed in, while switching over to the new framework, there are various ideas, fail to reach an agreement.
McCartney says, their university might not withdraw x86 framework, because the efficiency of the chip of the server of Intel is improving progressively. For example, supercomputer of Carter of Purdue University, ranks the 54th in the quickest TOP 500 billboard in the world, and Intel each index of performance chip offer and 4 Taiwan the intersection of Intel and the intersection of chip and total of supercomputer not bought it compares to be but also high before the 4 year.
“I can give up these 4 old machines, the present machine only uses 1/4 of the electricity to run the past, “McCartney says. The intersection of Intel and performance / energy consumption of chip to will with every group of appearances of new chip group raise.
“There are some appropriate improvements more too than the respect on the space / energy consumption, we are very glad to the improvement of energy consumption, “McCartney says.
