LSI introduces MegaRAID 6Gb/s SAS control device of second generation
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.
Stock situation
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..

Kindness Pu pay the intersection of industry and the intersection of performance and most high little controller based on Cortex-M3 intelligently
———-Series LPC1700 authorized through EEMBC expand 512 KB flashing memory and select now
Kindness intelligent Pu’s semiconductor NXP Semiconductors Confirm recently, according to the embedded microprocessor basis association EEMBC Test result,LPC1700 series is for industry performance supreme. EEMBC test result reveals, while running at the same clock speed, LPC1700 carries out the speed of the application program code than nearly 35% on average of other main Cortex-M3 competition products. When LPC1700 runs at higher clock speed, the performance advantage of intelligent Pu of kindness is more prominent. LPC1700 has already been authorized through EEMBC 72,100 and 120 MHz. Intellectual framework, flexible direct memory that the improvement of speed and efficiency owes much to this little controller are visited DMA Use with the best flashing memory of the market. LPC1700 series aim at operating while having outside communication of high bandwidth such as Ethernet, USB On-The-Go/Host/Device and CAN at the same time, the communication bottleneck will not take place. Products design object include electronic instrument, illumination, the intersection of industry and network, warning system, getting white family expenses and the intersection of electrical machinery and the intersection of person who control and extensive application.

EEMBC president Markus Levy says: ” These EEMBC test results authorized have proved a fact effectively: Design, memory interface and the processor kernel of the little controller are equally important. In addition kindness Pu test EEMBC their a goal pay the purpose to authorize, it is to add the dual fail-safe for these credibilities of scoring intelligently. The so-called credibility, these scores are repeatable, and produced according to association’s set rule. ”
Kindness Pu endeavour, offer more 32 little choice of controller to customer intelligently, add two new member for very popular the intersection of LPC1700 and series: LPC1768 and LPC1758. The two adopt LQFP100 and LQFP80 to encapsulate, expand the size of largest flashing memory of series LPC1700 to 512KB separately. Series LPC1700 have already produced the goods in batches now, such as needing free print, please visit www.nxp.com/experience_MCUoptions/.
Semi-conductive Vice President’s little controller product line general manager Geoff Lees Pu intelligently of kindness: ” The intersection of EEMBC and test result of us confirm LPC1700 series nowadays fastest, the intersection of efficiency and supreme Cortex-M3 little controller at the market. Series this person who begin produce, offer new the intersection of 512 KB and the intersection of flashing memory and apparatus, guarantee kindness Pu continue, provide most complete 32 little controller for customer, choose intelligently already. ”
Kindness little controller series LPC1700 Pu offer the following characteristics intelligently:
- Supreme bandwidth Ethernet
USB On-The-Go/Host/Device, makes it have industry most extensive USB to select
Interface and electrical machinery of the orthogonal encoder control the pulse width modulating device PWM ,Can realize flexible electrical machinery control and save the power
Interface of two CANs
