Technological revealed secrets of cache of hard disk of Intel Z68 solid condition
Buffer technology as to Smart Response Technology solid condition hard disk that Z68 chip set that Intel will be released soon supports, we have already analyzed in detail a few days before. However, a question that everybody cares about most was not answered yet, that is: What size can Intel, this technology, bring to characteristic of hard disk on earth promotion?
A few days ago, demonstrated within a Intel the slide was exposed in the network, revealed the answer to a riddle of the question at last. According to the official test of Intel, in Core i7-2600K, person’s DDR3-1333 memory once of 2x 2GB money, on Windows 7 64bit SP1 platform, use a piece of western data 1TB SATA 3 solid condition hard disks, and a Intel ” Larsen Creek ” 20GB solid condition hard disk, utilizes the solid condition hard disk of Z68 to buffer technology and construct ” mix the hard disk ” ,PCMark 05 hard disks of scores that can be made systematic are promoted by 355.5%, the toggle speed of the operating system is improved by 19.4%, machine available-time reduces to 28 seconds from 35 seconds.
In fact, this technology of Intel has a long history, can trace back to ” flashing memory slot ” appearing by batch P55 chip set mother board memory slot initially . The technological coaxiality Braidwood at that time, just used flashing memory as the hard disk to buffer, promoted the magnetic disc characteristic.
Acceleration flashing memory slot that appeared on the first batch of P55 mother boards that yearAnd reached this generation, popularize the improvement of the intensity with the hard disk of the solid condition, it was moved towards at last practically that the hard disk of this solid condition buffered technology. Moreover, Intel will take this opportunity to popularize one’s own solid condition hard disk products too. For example ” Larsen Creek ” appearing in the official side tests The low-end solid condition hard disk that Intel will be released soon, is called series 311, the leading ultra low price, the price may be less than 50 euro, capacity only has 20GB, it is all tense to install the operating system, but just accord with the requirement for buffering the minimum capacity 18.6GB of technology of hard disk of the solid condition. Users can not see an incantation of the hard disk of the solid condition while opening this technology, will totally use it as cache of the hard disk.

Hot revealed secrets of great innovative trend of the solid condition hard disk 10
The hard disk of the solid condition is still a present hot topic, in earlier memory network world conference SNW held of this month Have, the product exhibition about the solid condition hard disk emerges in an endless stream. It seems that half of manufacturer is all peddling their newest flashing memory products.
At present, the price of the hard disk of the solid condition is dropping with 50% of the ranges of every year, the heat degree of the hard disk of the solid condition is not being reduced continuously, the traditional hard disk seems to go to the end. But the writing brush of analyst Jim of the company Objective Analysis of market survey is guided Jim Handy But does not think so, he says the traditional hard disk without knowing the stage of backout history forever. Perhaps the price of the hard disk of the solid condition really drops quickly, but the price of the traditional hard disk is jumping down.
The writing brush is guided and said: “Just like the old cowherd in the past says to the marksman in new era ‘ stand firm, it is the same that I want to shoot you to death ‘. But the hard disks of the solid condition and price of unit capacity of the traditional hard disk all drop at the speed of 50% for every year. ”
However, there are too many advantages of the hard disk of the solid condition. What the following is stored and exhibited at the network world conference is about innovating and employing some technical cases.
1,Virident
Virident has a section of PCIe solid condition hard disk products similar to FusionIO, its most outstanding place is that a characteristic is steady, and the flashing memory module can be changed. The capacity of Virident tachIOn PCIe SSD solid condition hard disk products is divided into 300, 400, 600 and 800GB several kinds. Virident channel executive vice president Jorn and Morfil claims: “Use our solid condition hard disk products, needn’t change the storage card namely replaceable flashing memory module. In addition, most miscellaneous solid condition hard disks can’t guarantee to keep the stable characteristic under loading for a long time, but this point that our products are possible. ”
Virident guarantees the steady characteristic of the hard disk of the solid condition with dual control device architecture. Looking forward to the future, Morfil estimates PCIe will be popularized applying to traditional hard disk size solid condition hard disk products soon. The reason is: From employ processor to be close to can let, improve assumed speed a bit data of letting, this is much better than to utilize the method that SAS/SATA connects technology and inserts the hard disk of the solid condition in the traditional hard disk slot.
2,Viking
Viking Modular Solutions has offered the solid condition hard disk of the high capacity for the fact that enterprises stored and the server is employed. SATADIMM is the highest can offer SATA characteristic compatible SAS of 60000IOPS, 6Gb/s ,Than the traditional solid condition hard disk use 2.5 traditional the intersection of hard disk and outer cover floor space Should lack 75%, it uses DDR 3 DIMM slot.
Storage system framework teacher Jonathan and Hinkle of Viking claims: “If can obtain more high characteristic by inserting the hard disk of the solid condition in DIMM slot, why insist on using the traditional solid condition hard disk? Do not need to replace the low priced hard disk with hard disk of the solid condition, will reduce the memory capacity like that, you can continue using SATA hard disk, making use of spare DIMM socket to increase the flashing memory at the same time. ”
For example, using a large number of systems of RAM memory at present can change some memory into the flashing memory of TB grade, thus offer the high performance of the bigger data set. The heaped capacity of SATADIMM is 480GB.
3,StorSimple
StorSimple 5000 and 7000 mixed cloud products include a solid condition hard disk crest floor. StorSimple carries on this expanded purpose, when the backstage supporter have data the load solid condition hard disk, repeat the data to delete and deal with through hard disk crest layer of this solid condition. In this way, can reduce the data bulk that must be sent to each cloud service supplier such as Amazon, EMC Atmos, AT

SAN and NAS store the virtual difference
Within short a few years, store Virtual Have already proved it has been worth and pass by the old road from up-market solution of costing an arm and a leg to goods of the moderate price in the big enterprise. As a standard function of the memory array of most middle levels, storing and turning a medium and small organization fictitiously solves extensive memory and manages the difficult problem. At the same time, the special solution of the first-class manufacturer has offered the greatest investment repayment for the fact that manage the large-scale enterprises with large-scale memory LAN of the intensive data usability demand.
Store virtual to establish first abstract layer store, in host computer and physics, have concealed the characteristic of storing the apparatus singly. When implementing while storing the LAN in one, it has offered a single management for the fact that all piece grades are stored to click. To be simple, store virtually and store a plurality of varied networks apparatuses to concentrate together, offer one group to store one and is used as host computer fictitiously.
Besides establishing the memory pool composed of physical hard disks of different arrays, store virtually and offer the extensive service in unanimous way. These services begin with basic roll management, including LUN logic unit number Shield, connect in series, roll divide into groups and segment, simplify disposition and automatic roll expand and automatic data move and data protect with disaster recovering the function including the snapshot and making mirror images . In brief, the virtual solution can be used as enforcing and storing the management policy and realizing a central control point of one grade of agreements of higher service.
Perhaps the virtual most important services that realizes are not to produce the confused data to move. To large-scale organization, it is almost the life fact not changed to move the data. Since the end of old apparatus lease and reach the standard grade with the new apparatus, storing virtually can realize that move without cutting off the service to piece one grade of data of another apparatus from an apparatus. Store administrator’s maintenance very apt to carry on the walking example or change the outmoded memory array, will not interfere with application program and user. The production system will keep running.

Choose the passway exchanger of optic fibre to have a better method
Differing widely with Ethernet exchanger, most users are while constructing and storing, FC exchanger often closely integrated in the system. Users pay close attention to intensity not height, on the other hand all OEM optic fibre passway exchangers of apparatus manufacturer of large-scale memory to him on one hand, non- careful user’s even manufacturer of the exchanger is not clear.
Basic page
In the eighties of the 20th century, connect host computer and it stores standard methods of apparatus to be through look like or IDE walk abreast point-to-point DAS that interface realize connect and store directly such as the SCSI Way. It is offered the speed 5MBps or 10MBps of relatively fast visit SCSI hard disk that SCSI runs side by side ,And several hard disks can be coupled to computer through the same interface.
However, with becoming bigger and bigger to store the subsystem, the computer makes more and more fast, a new problem has appeared: The outside stores the apparatus and begins to become huge. Tape storehouse, RAID the redundant magnetic disc array cheap Begin, need increasingly many space with other the intersection of SCSI and apparatus, this demand, run side by side SCSI connect, extend, come out far from host computer. Meanwhile, I/O input / export The speed is increasing constantly too, then what a big bundle of threads 32 or 64 data bus China keeps the consistency of the signal too on the issue to need to solve in physics as one. SCSI purpose of design of improving edition of simple running side by side lies in, increase the distance of data transmission and solve the consistency problem of signals. But they formidable high-speed signal transmit this technological difficult problem under walking abreast SCSI bus framework finally.
In order to meet these new demands, people have developed the optic fibre passway Fibre Channel offering the access ability of one giga of serial networks for storing the apparatus Agreement. Have set up SCSI agreement used for storing based on optic fibre passway on the fourth storey of the agreement of optic fibre passway, fictitious interface VI used for cluster used for IP agreement and shining upon the network framework of the network Agreement. Optic fibre the intersection of passway and agreement synthesize a lot of advantage, until the intersection of network and range can remotely up to 10 kilometers most, can use simple serial cable, one giga of network speed of many kinds of mediums and can use many kinds of agreements on the same cable at the same time. Characteristic these make optic fibre passway agreement the intersection of SCSI and replacement of agreement approve by people the 1990s while being whole as walk abreast, the passway agreement of optic fibre is used in overwhelming majority high capacity, high side and stored on the apparatus in succession straight now.
With replacement’s appearance of point-to-point way that the passway agreement of optic fibre is regarded as to run side by side SCSI, and as it is accepted by market gradually, the simple memory of a kind of association employs presenting

Measure the hard disk of the solid condition (SSD) Characteristic correct method
According to relevant person of Intel, in the following several years, Intel IT adopts 100% the hard disk of solid condition SSD solution, and SSD will inevitablely become the major solutions of enterprise IT departments compared with the superiority of the traditional mechanical hard disk. But because SSD preparation method and technical innovation, lead to the fact that it is far different from traditional machinery hard disk detecting means to measure SSD characteristic method. Then how to measure the characteristic of SSD correctly? This the intersection of present section and question that discuss that course want.
Importance of the performance test
It is except that hard disks are different to have the picture, other software and hardware dispose two identical large G60J note-books in China, Taiwan – -Intel cool Rui i5 M430, Intel HM55 chip set, 4GB 2X2GB DDR3 DRAM , Great Britain big to up to GeForce GTS 360M display card, Windows 7 Home Premium 64, last 10.1.0.1008 Intel Rapid Storage Technologr. in system in HDD Momentus the Seagate ST9500420AS 500GB HDDs of 7200rom; SSD system uses the series of the solid condition hard disk 320 of 300 GB Intel.
Therefore, the performance test is very important to enterprise IT department.
Ingenious and complicated SSD
SSD is with page load, but it regards block as the minimum unit to erase. So brand-new SSD can reach the optimum performance because of the data order load. But SSD that use, new the intersection of data and the intersection of load and blank area, then the basic data are marked invalid, when needing obliterated data, with NAND data block block Erase for the unit. It summarizes, there are the following two pieces of course:
Move the useful data block;
Erase the data block and upgrade the data mapping table.
Metric method of the characteristic
Because SSD adopts the brand-new preparation method, in order to weigh its quality in an all-round way, specially adopt the following measurement methods:
Comprehensive test method
Regular I/O operation order, random read/write
Typical tool: Iometer, CrystalDiskMark
Applied test method
Adjust and weigh through the way that and the script of real application uses time
Typical tool: SYSmark
Orbit type test method
Record I/O operation sequence of users or scripts and return
Typical tool: PCMark Vantage, HDD Score
That different test method receive the intersection of antithesis and result ‘
Worthy to be gratified: All measurement methods reveal SSD is much faster than HDD
And existing problem: To identical SSD, different test methods will cause different results
The comprehensive test method is too simple to SSDIt should be optimal, most close to the real operating position to employ testing, but only a small partial systematic test index is sensitive to the hard disk. Even then it often has comparatively definite associativity with hard disk too that the sensitive form of the hard disk is employed. For instance:
Sensitive to CPU: Format conversion of MPEG2 to MPEG4
To both all sensitivity: Turn on the editing machine of the video
Sensitive to the hard disk: Load MPEG2 file, keep MPEG4 file
The test method of the orbit: Potentiality is limitless
The true application situation of simulation that the test method based on orbit is very good:
Track and gather all of realistic users’ I/O operation
Then return to to test one I/O orbit gathered
It is right to test to return in the course I/O of one gathers tracing again
It was I/O operating time that was recorded, but not the time that the system dawdles
Different orbits
Vs set up artificially is actual; Use the modal difference, acquisition time is short and vs long
In addition orbit sequence is worth considering
Different playback methods
Different tools and options, the orbit does not add the modification to return vs to return after revising directly
The data are packed in advance, the single task order runs, multitask running,etc.
Different statistics indexes
It is high to burst out the part and return vs all orbits and return vs to both make up
Vs time when MB/s vs prolongs
The data are packed in advance Actual influence of
