DS5020 is that IBM begins to supply in one section in September of this year the end stores the new products, its introduction, do not have low end products situation after remedying series IBM DS5000. Store the little introduction of manager’s money of the products according to IBM system and Greater China district of Ministry of Science and Technology, DS5020 has been promoted by more than 70% compared with DS4000 its performance, therefore suit the application demands of small and medium-sized enterprises further.
DS5020 has 4 available ports, 4 8Gb/s foreign ports, the quantity of the largest magnetic disc is 112, it can be that FC can adopt SATA plate too. Though there are only 112 magnetic discs, the back interface of the system adopts interface of 4 8GB/ses, in this case, greater than 112 magnetic discs, its systematic function will have influence, so over 112 magnetic discs, it is useless to promote instead as to systematic function. In buffering, DS5020 has offered the option that 2G, 4G buffer. Gold points out a little, in the ABC of memory system of grade, it is not obvious to add too and buffer results got up, consider the cost factor as a whole, 4GB is a good choice.
Gold points out a little, the ones that need paying attention to are: 8Gb/s twice that of 4Gbps, for store but speech, network connect bandwidth raise, magnetic disc connect bandwidth change inside the memory system, analogous to right away then of ” the door ” It is wide to change, still can’t improve the performance of the whole system. The inside design in DS5020, has put out the new port, so its whole performance is improved to some extent.
In management software, DS5000 simple compared with DS4000 in software, the intersection of interface and humanization further, operation is easier too. In addition, DS5020 has offered the dynamic RAID function, needn’t shut down, in fact RAID1 0 can change into RAID 5, can operate online directly.

SGI claims to introduce the new and file the platform today, it is 1.4PB that this files the platform capacity, and offer automation to store the framework hierarchically. This product will be expected in May outloading.
The the intersection of ArcFiniti and filing system it stores to be by one main the intersection of cache and layer and one file layer, make up hierarchically. One layer of range of capacity of cache is 20TB to 60TB, it is furnished with 1TB 7200rpmSAS driver on RAID-6.
It is 156TB to 1.4PB that RAID-5 furnished with 3TB 7200rpm SAS driver files range of capacity. The total available capacity is reached from 176TB to 1.46PB.
ArcFiniti filing system based on file is developed on the basis of Copan Systems, this is technology that SGI was purchased one year ago. SGI products manager ArcFiniti show, put out the edition which will support NFS in May and but will put out the edition which will support CIFS in July or August.
” power-managed ” of ArcFinitii File Massive Array of Idle Disks MAID of layer Copan adopted Technology.
Because of adopting energy-conserving MAID technology, so ArcFiniti under the whole working condition only consumes 7071 watts or 24127BTU. In other words every TB consumes 5 watts or 17.2BTU.
This product still offers and drives measuring while transferring to the spare hard disk drive in data.
Five kinds of different ArcFiniti platforms that dispose are available. ” low to buy ” A156 including 176TB available capacity whether last layers of 20TB, last layers of 156TB ,Interface of three GbEs and interface of two 10GbEs. A156 price is 191,842 dollars.
Available capacity buffer layer 60TB, files layer 1.4PB of advanced A1404 including 1.46PB ,Interface of nine GbEs and interface of six 10GbEs. A1404 price is 1,058,921 dollars.

A few days ago, LSI Company announce supplier put out group their on the intersection of 6Gb/s SAS and technical secondary MegaRAID SATA SAS RAID control card to channel. New serial MegaRAID control devices adopt LSI dual kernel 6Gb/s SAS RAID ROC on slice IC, have realized most high service device RAID characteristic of the industry, has further expanded the characteristic leading advantage of the existing LSI MegaRAID 6Gb/s SATA SAS control device.
The global channel of LSI is sold and a market director Brent Blanchard points out: “LSI has already put out 400,000 groups in MegaRAID control card of 6Gb/s SAS technology, and our rival has just claimed to introduce 6Gb/s SAS control device recently. Prominent our lasting leading position in SAS and RAID technical field of introduction of the second generation products, and will help users to realize the characteristic of the solid condition driver will be maximized, thus further improve investment repayment, strengthen the competitive edge. ”
New serial control devices include having MegaRAID SAS 9265-8i and MegaRAID SAS 9285-8e with 8 outside ports of 8 internal ports, the characteristic level exceeds RAID 5 random I/O 200,000 times of every second, compared with former generation products, the characteristic is promoted by 3 times. Users pass the single control device backed by LSI MegaRAID FastPath software, and connect with 8 SSDs, promote the characteristic to RAID 5 random IOPS 465,000 times. This kind of high level software can offer high-performance I/O for SSD linking with MegaRAID control device and accelerate the function to select, fully give play to the characteristic advantage that SSD disposes.
If the high performance 6Gb/s SAS RAID control device of the similar competition products wants to realize the same IOPS characteristic level, need to reach 3 extra RAID cards, 24 extra SSDs and 3 pieces of outside JBOD storage equipment to support 12 drivers more. This not only needs to improve space of framework and power consumption by 3 times, will also increase the purchase cost of the hardware by a wide margin at the same time.
In addition, the new control device offers RAID bandwidth with leading industry, supports 2.7 GB/s order reading and 3.2 GB/s order load throughput, this characteristic produces 60% higher than the similar competition products. Whether could offer the industry highest RAID IOPS and bandwidth characteristic to meeting the database and applied high I/O transaction demand of cloud, it is essential to accord with finance, digital media, Web 2.0 and medical imaging and employ the required bandwidth requirement.
The cheif technology officer Keith Josephson of ION Computer Systems Company points out: “The new LSI MegaRAID 6Gb/s SAS RAID control device makes ION SR-71 SpeedServer system top the characteristic barrier of 1 million IOPS. Utilize these characteristic remarkable new-type control device, SR-71 SSD person who optimize server can realize, exceed 100 characteristic of IOPS Wan, still can carry out the random reading of 1KB at the same time, response time is less than 200 microseconds on average. MegaRAID control device has extremely high IOPS and extremely low time delay, thus make SR-71 of ION employ the engine to offer the outstanding characteristic that the magnetic disc type solution can’t realize, and the low power dissipation is in 500W. ”
The control device of the low sectional MD2 size adopts LSISAS2208 SAS ROC IC, 2 800MHzs imbed formula PowerPC processor kernel and 1GB DDRIII cache memorizer. These cards support to reach hard disk drive or SSD of 240 SATAs and SAS high, support hardware RAID 0, 1, 5, 6, 10 and 60 grades to dispose at the same time. Intelligence is new-type can select backup unit of batteries LSIiBBU09 to adopt the more high electrolytic bath technology of the hot tolerance, can improve the data protection function, and offer the sufficient flexibility to persons who construct systematically, can install LSIiBBU09 distally to independent PCI edition RMB Have, can also be independent of chassises.
The new MegaRAID control device is carrying on the show MegaRAID SAS 9265-8i among them on CeBIT 2011 that Germany Hanover Convention and Exhibition Center holds this week The control device has already been put out formally. MegaRAID SAS 9285-8e expected to put out at the end of March. The co-product is put out through LSI global retail trader, integrating trader and VAR network.
New control device enrich industry further the intersection of channel and the intersection of field and most overall 6Gb/s SAS and SATA store construct pieces of the intersection of solution and range of product at present, among them include MegaRAID and 3ware? RAID control device, Host bus adapter, WarpDrive SLP-300 card, SAS switch, JBOD storage equipment, CTS2600 series configurated store assembly and high level software and select etc..
