Though the server of the blade has been the apparatus that the data centre has immobilized all the time for many years, but the situation changes delicately now, some strange factors force a lot of enterprises to use the framework type server to replace the server of the blade. In fact, these factors may indicate the design idea of the whole data centre is changing. ...
World is changing.
Hold the strength that the cloud calculates under the arm, is moving Internet and assaulting a lot of traditional industries, and offered the open platform for new industry. Brand-new connection and communication way seem to change people’s life and work overnight, but commercial mode and mode of operating of business of the novelty of various reality that a following one is. Information, communication, calculate, human society these depend on element shaped to condense get into unprecedented ” make the best use of everything ” through the ages ,Release ten million times of energy, bring more vigor and commercial opportunity to global economy.
“In the past 5 years, iPhone is the hottest consumption electronic product beneath most mention of whole world, No ” ,U.S.A. famous the intersection of IT and the intersection of website and discovery of eWeek confirm global market to move the intersection of Internet and consumption enthusiasm of science and technology extremely fine. In the traditional trade, with iPhone, iPad is supporting enterprises to manage high for representatives’ new portable terminal, medical worker, administrative staff of hotels and the airport,etc. move workers to move and work doing in an expert way through moving Internet, send out the order whenever and wherever possible, follow up the working project, meet the customer, operating long-rangely and video conference. Information and group extremely easy to obtain cooperate and support them to make wiser decision in time, create more value for enterprises. In the highly flexible intention type industry, pursue the designer with free greatest intensity, crowds such as artist, music creator, free-lancer, products salesman, analyst, entrepreneur,etc. have obtained overall support through moving Internet, brand-new commercial mode and point of economic increase are emerging constantly.
The flexibility of the economic mode makes enterprise’s administrator rely on efficiency and innovation that IT system brings for counsel more and more. CIO face means changes and challenges brought of the whole new technology at any time too while bearing the pressure inside enterprises. BYOD Bring Your Own Device The most attractive IT employs the trends at present. BYOD, namely carry one’s own apparatus and work, while its advantage lies in raising the staff’s working efficiency, reduce enterprise IT cost and input. These apparatuses including PC, mobile phone, dull and stereotyped computer etc. move the intellectual terminal device. Stemming from individual and innovating the behavioral BYOD mode stimulates the staff’s creativity greatly, approved day by day, trade investigations reveal, China has already had 78.9% of the enterprises that have allowed the staff to use personal mobile devices to work at present by enterprises, 8 percentage points higher than integral level in the Asian-Pacific area. But seen from the present, it is one grade of portable terminals of staff’s personal consumption that BYOD has involved many mobile devices, this has brought the suitable difficulty for IT system management of enterprises, and bury the potential safety hazard.
The more competitive advantage what the staff innovated and brought to enterprises is, enterprises need to encourage and support the innovative behavior. Move flourishing development of Internet, make BYOD and the intersection of enterprise and IT whole and synthetic for major issue that instantly can’t neglect in system. But in practice, how does BYOD bring more additional value to enterprises instead of more trouble and potential safety hazard? How combine get the intersection of enterprise and IT in the system the intersection of staff and personal productivity of mobile device? These problems are demanding prompt solution.
What deserves to be mentioned is, in all BYOD move the intellectual apparatus, the proportion of the serial products of apple has occupied the first. In 2012 the report points out, only first quarter of this year in the wealth season of second in Apple, Chinese district iPhone sales volume increases by four times compared with the same period of last year, achieve the new highest record in history, the demand for iPad behaves powerfully, the sales volume of Mac has increased by 60% compared with the same period of last year too; And apple operating system and the intersection of enterprise and the intersection of Windows and compatible question between the system that mainstream adopt give, expect enterprise of trend this bring system to be compatible through BYOD Great difficult problem. To the trend of this market, in order to solve security and compatible problem of serial products of apple and enterprise IT system, global and leading host computer, the cloud has served and put out Parallels Desktop 7 for Mac solution and enterprise edition with the virtual provider Parallels of tabletop in order to meet market demand.
It is the apple Mac quantity specially Parallels Desktop 7 for Mac that the body makes is the fastest, most ocular Mac desk-top virtual system at present of the industry, first in the world of comprehensive rank.

Computerworld website published the article and claimed, IBM researchers obtained the great technological break-through in the field of electronics of spinning a few days ago, can lengthen the cycle of spinning of electron 30 times, thus expected to break through ” terminal predicament ” that memory trade faces ,Initiate the new round ofly in the future ” Store the revolution ” . The following is an article full text:
The famous science periodical ” Nature ” will publish a thesis written by IBM researchers this week, they claim to obtain a great technological break-through in the field of electronics of spinning, can be in order to improve the memory and store the memory ability of the apparatus, can reduce its energy consumption greatly at the same time notably.
What is electronics of spinning?
Electronics is to spin ” Spin and move electronics ” Abbreviation,it is that it can last electron at magnetic field for spin and be combined to last head, record and read the digit data on the semi-conductive material.
Through changing the relative axial of the electron in their spaces ‘ Upwards or downward ,The physicist can represent the location of data with it. For example, the electron is ” 1 ” on the upward axle ,And the electron is on the downward axle ” 0″ .
For a long time, it face one of inherent problems, because electron electronics of spinning ” upwards or downward ” Direction state can only keep 100 psec – -1 equivalent to 1/1,000 billion for one second ‘ 1 is received for 1‰ of second . 100 psecs are not enough to carry on operation, so the transistor can’t finish the operation function, it is not lasting that the data are stored.
IBM lets to spin the electron is danced big ” The group dancing ”
In publish in the research of ” the Nature “, the intersection of IBM and research institute and federal Institute of Technology are abbreviate as ” ETH “, Zurich of Switzerland, Solid physical laboratory announce, a synchronous method that they find can spin electron cycle lengthen, receive second to 1.1 by 30, this is the operation cycle of 1 GHz processor too.
Scientist Saris in Ji’an Gian Salis of the union author of this thesis, physical research group of nanometer of IBM research institute Show, the scientist of IBM utilizes ultra short laser pulse to monitor the spin that hundreds and thousands of electrons produce at the same time in the small places of one, thus understand the change of the state of spinning of these electrons.
Generally, these spin the electron will be rotated at random and lost directionality rapidly. In the research, the researchers of IBM and ETH have found how to present neatly the method that a banding arranges of the free electron for the first time, this kind of permutation is known as again ” The invariable spiral of spinning ” persistent spin helix, is abbreviated as PSH .
Saris points out, ” spins and locks ” This concept was put forward first to 2003, some experiments found that this kind focused on sign that existed to prove this kind, but no one has observed this course directly up until now.
” the rotation of the direction is totally independent to spin ” Saris says, ” we can let this kind realize moving ahead simultaneously rotatably now, thus all rotate along the same direction while letting the electron keep spinning, just like uniform group dancing. ”
“We have already totally grasped this course, and already proved this theory. ” He adds.
It is electronic it is spiral to spin pursue mode and ” The invariable spiral of spinning ” PSH picture comes from computerworld
Create the electronic industry’s new opportunity
The researchers of IBM adopt GaAs as its main semi-conductive material, this is current electronics industry, diode and a kind of commonly used materials of solar cell.
The computing technology of today carries on code and treatment of the data by electric charge change of the electron. But researchers point out, when the size of the semi-conductive material lessens to the electron and can not flow controlledly, this technology has been limited.
For example, the circuit width that NAND flashing memory products used has already been smaller than 20 nanometers, this is close to the atom size size. But through controlling the spin but not electric charge of the electron, electronics of spinning can overcome this predicament that memory trade faces.
This kind of electronics is understood newly, not only can let the scientist control the electromagnetic sports within the apparatus unprecedentedly to spinning, also made the electronic apparatus with higher efficiencying creates the new opportunity.
In the field of electronics of spinning, IBM is not the only person who studies intensively technology.
Three years ago, material physics of Strasbourg of France and physicists of the chemical research center set up new laser technology on the basis of electronics of spinning, and obtained Nobel Prize for physics in 2007.
These French physicists have found a method, the memory that can make use of laser to accelerate the hard disk is imported / exported, make it than existing to read and write the speed to raise by 100,000 times.
One of the questions that electronics meets of spinning, a magnetic sensor used for measuring the location of data is too slow in speed. But in 2007, a research of France is published in the scientific periodical ” nature – physics ” Nature Physics Go, research group this use ” fly to second ” namely 1‰ of 1.1/1,000,000 billion psecs of one second The laser produces the laser pulse ultra and quick in speed, thus change the electron and spin, so has accelerated reading and writing the course.
The researchers of IBM say, say the break-through which they made has opened up the road for transistor and non-volatile memory, the energy consumption of such new memory technology will be well below NAND flashing memory technology of today.
Need extreme low-temperature environment
However, a very great crux lies in – -Researchers can’t receive the ideal result at the room temperature yet at present, but the temperature of the normal range is produced to the reality of processor and memory apparatus very important. Come, look at present, experiment this in low to 40 Kelvin only Extreme at low temperature could go on.
“There is no such an apparatus now, but this is that one is broken through, we grasp and lengthen the method of cycle of spinning in the ditch one of electron. ” Saris say ” and then we want one thing that do, it spin for cycle Lengthen 30 times. ”Share the button

Begin to be having AMD to cooperate with ARM from the financial analyst’s meeting at the beginning of the year constantly, even adopt ARM and authorize and march into the rumor which moves the market of processor, but at AFDS conference of June, ARM not only participated in HSA foundation of AMD, it and AMD ambiguous and unidentified relation is also confirmed, it is not quite alike but with everybody’s imagination.
AMD has really obtained the arthorization of IP to apply to the future APU products from ARM, but not intact series Cortex, but TrustZone safe practice. Since first application of Cortex-A5 framework in 2004, it has been already long-tested that TrustZone technology of ARM protected respect of employing such as DRM, online security to pay etc. in the data.
Superenergic network bring one relevant AMD use the intersection of TrustZone and the intersection of analysis and article of technology today, besides recommending the application principle of this technology, include why AMD chooses TrustZone, and market competition and opportunity faced.
See PPT of AMD propagates, their original working way is vertical, it is the chip – platform – software – service respectively from top to bottom, it is horizontal now, CPU-GPU – third party IP kernel. But disgusting trough, the PPT to make, show investor, understand, have one third party authorize why have such a big transitions really?
Get back to the subject, have a look at composition and principle of TrustZone.
TrustZone framework designed
TrustZone has two kinds of work patterns, one is normal mode Normal World ,Can carry out the rich order, is called REE environment Rich Execution Environment ,Another mode is a safe mode secure world ,Can only carry out and receive the letter order, become TEE environment Trusted Execution Environment .
TrustZone sketch map
These two kinds of modes are integrated in a kernel, it is very apt to let people recall similar Intel HT ultra thread technology, TrustZone is not that a pair of thread runs side by side or runs synchronously in fact, it has a thread only, but switch over in two kinds of modes briefly according to the needs of different one, situation with cores single with when run it is many there are similar on task,can’t be too can watch by video while not surfing the Net, it is this sample.
Other necessary conditions
Think there must also be other conditions to cooperate in intact realization TrustZone, it is TrustZone hardware at first, the processor thatting is to be similar to Cortex-A5, then the related system software, this highlight most too, mainly two manufacturers are making.
One is MobiCore of Giesecke ...
Not long ago, until ” whether the intersection of x86 and server performance promote mean RISC/UNIX comes to a dead-end greatly” View industry dispute because fierce rather, relevant to support data not to be emerged in an endless stream too.

Though is expensive for the second largest x86 processor manufacturer in the world and contending with the giant Intel for decades, but AMD state during these years is really not good, will spread out of the news purchased often. Superenergic network reports, AMD stock price rose by a wide margin suddenly recently, while it is said AMD may be purchased, and the target includes high pass, Samsung in full swing now.
Although ” spread ” , “or ” Such news is the most horrible, but this trade is like this, full of rumours, some Cheng Zhen, some talk nonsense. As for true this time, can only wait a moment for, think.
AMD stock price and market value
AMD stock price of this Tuesday goes up by 8% and reaches 4.34 dollars the sectional drawing was shown 4.45 dollars just now all the way ,The ones that support this amount of the increase ” Good news ” It is AMD that will be purchased by another company. The market analysis expert Patrick Wang of Evercore Partners Company calls high pass and Samsung the potential AMD buyer.
Though he touches on lightly to this rumor, expresses the same day Really a lot of sell short and refill the trade in the afternoon.
But Martekwatch shows this rumor is unlikely to become reality, but we mend in the brain along the rumor, whether high pass or Samsung may purchase AMD.
Have got rid of Samsung first instinctively. Though there is possibility of purchasing AMD on Samsung’s both scale and capability, but AMD know the intersection of x86 and the intersection of processor and designed capacity, trade this get U.S. government and approval of Congress while being impossible. Even if the ally where South Korea is U.S.A., but Americans foreign people are not enough to believe in, it is impossible to allow the sophisticated technology to outflow, see the situation of F-22 knows.
The ones that may be regarded as the example Weisheng purchase Cyrix and and thereby have company that x86 authorized as the third, but Cyrix scale and influence on x86 are really too small, it is unable to equate with AMD.
So even if Samsung purchases AMD intentionally, it is finished that this transaction is impossible, so Samsung can get rid of.
Stock price and market value of high pass
The high pass has relied on ARM processor to cross flourishingly during these years, the present stock price is 61.50 dollars, the market value reached more than 100 billion dollars, sought and accepted more than 15 billion last year, Q3 camp had charged and already reached 4,600 million dollars this year, the profit is 1,210 million dollars, it is OK to swallow and lose the market value and is fewer than AMD of 3 billion on the financial affairs.
Is there any benefit after the problem is that purchases AMD in high passing? High pass sit steady the first already in the field of ARM, a satisfactory one 28nm of Taiwan Semiconductor Manufacturing Co. it produces to be can enough, the valiant dragon S4 of new generation is a bit in short supply. Purchasing AMD can march into x86 and figure business, the rivals of these fields are much fewer than ARM field, there are only Intel and NVIDIA to say, AMD arranged with patience and enduring resolve for so many years and did not send the rival and fall either, will lack the high pass of the experience in this field to take risks?
If the high pass determines to purchase AMD, there is no question on policy and financial affairs, just for high pass, there is business of fortune for money that has not been made enough yet, why go to the muddy water of x86 once and display card?Share the button

According to the original plan, Trinity APU released this year will be replaced by Kaveri APU of future generation next year, but according to latest news of the medias of foreign countries, though Trinity APU there is life-span in one year, but its family will get further expansion at the beginning next year, Trinity 2.0 will appear in a certain time of next year as its upgrading edition.
But this does not say Kaveri will jump the ticket ‘ It is possible ,According to the other matchmaker’s statement, this is that normal products are upgraded, nothing more than carry on light maintenance Bug of the framework youngly and so as to upgrade and walk into to mend, whether promote the frequency in order to reach stronger performance or reduce some consumption. Haswell processor of Intel will appear about next second quarter after all, Trinity APU will face the great challenge when the time comes, so AMD puts out Trinity 2.0 in reason in next first quarter or initial stage of second quarter.
