LSI 9300-4i4e HBA – Next Generation 12gbps SAS 3 Performance

 The LSI 9300-4i4e is a host bus adapter (HBA) that offers next generation 12gbps SAS 3 connectivity. We have seen the higher-end server market move to higher performance interfaces for years now, and with the current generation of solid state drives, SAS 2 running at 6.0gbps was being saturated by many drives on the market. Unlike with mechanical drives, it is relatively easy to provide more performance from a SAS SSD and so SAS 2 was certainly holding the higher-end of the industry back in terms of performance. With the introduction of the LSI SAS 3008 and 3108 controllers, LSI is officially in the 12.0gbps SAS 3 game. Today we are looking at the LSI 9300-4i4e which provides both internal and external connectivity. Suffice to say, this card represents a new performance standard that we will see integrated in many servers going forward. e5-4620 v3 LSI 9300-4i4e Test Configuration Unfortunately, SAS3 is not yet a widely deployed standard, either from the host side or from the drive sid

ASUS Announces Support for New Intel Xeon E5-2600 V2 and E5-1600 V2 Platforms

At IDF13 in San Francisco, ASUS announced support for the new Intel Xeon E5-2600 V2 and E5-1600 V2 server platforms. This includes updating its server products for the new processors through BIOS updates. As we have seen with Supermicro, Gigabyte, and Tyan this is a common practice in the industry for this release. Existing owners benefit from the new, higher core-count and lower power consumption Ivy Bridge-EP architecture. New purchasers will get the benefits of utilizing platforms that are very expandable and that have been tested and tweaked for a significant period of time. Certainly this is an expected upgrade but good to see continued ASUS support in this area. Here is the official press release: ASUS today announced that its new-generation E7 servers, Z9P server boards, ESC4000 G2 and ESC2000 G2 workstations and Z9PE-D8 WS, P9X79-E WS and P9X79 WS workstation boards support the latest Intel® Xeon® E5-2600 v2 processors. The new ASUS server and workstation products designed for

Supermicro Announces Support for New Intel Xeon E5-2600 V2 and E5-1600 V2 Platforms

 Passing along the press release from the Supermicro launch of its Intel Xeon E5-2600 V2 and E5-1600 V2 products. Certainly, as we expected we are seeing older LGA 2011 platforms updated for the new Ivy Bridge-E and Ivy Bridge-EP processors. Supermicro is launching a few new products at IDF this year at the same time to support the chips. Another interesting part of the Supermicro IDF13 launch in San Francisco are the new products being launched. Some examples are the MicroBlade with the 8-Core Intel Atom C2000 processors, and up to 112 nodes. Another key is the 12gbps SAS solutions. We will have more on those solutions tomorrow but suffice to say, 12gbps SAS 3 is going to be the standard in the near future in servers. Check back tomorrow for more on this. Below is the copy of the press release. San Francisco, Calif., September 10, 2013 – Super Micro Computer, Inc. (NASDAQ: SMCI) , a global leader in high-performance, high-efficiency server, storage technology and green computing, intr

Gigabyte Announces Support for New Intel Xeon E5-2600 V2 and E5-1600 V2 Platforms

Along with other manufacturers such as Supermicro and Tyan, Gigabyte announced support for new Intel Xeon E5-1600 V2 and E5-2600 V2 product families. To support Ivy Bridge-E and Ivy Bridge-EP, Gigabyte is upgrading BIOS on many existing platforms to support the new processors. Also, Gigabyte claims to have technology (we have not verified this yet) to maintain 1866MHz memory operation even with fully populated DIMM slots. More to come in the next few weeks. The great news here is that there is another generation with significant power savings and performance enhancements (due to additional cores) that will drop into existing infrastructure. Unlike the 3-15% improvement we saw on the Haswell desktop side this year, the server-side has the capability to see 30-50% improvement with this generation by simply replacing chips. Below is a copy of the press release. Taipei, Taiwan, September 11 th 2013 – GIGABYTE Technology, an innovation leader in the development of high technol

Intel Xeon E5-2697 v2 – 12 Core Ivy Bridge-EP Benchmar

We are still about a month away from the Ivy Bridge-EP “officially” being launched. It, of course, has been at large Intel customers for quite some time now. Those are the same customers that are already running Haswell-E silicon. For the rest of us, we are still running Sandy Bridge-EP. We already looked at the Sandy Bridge generation’s top dogs including the Hyper-Speed dual Intel Xeon E5-2687W configuration. Now it is time to look at the next-generation LGA2011 Xeon: the Intel Xeon E5-2697 V2. The Intel Xeon E5-2697 V2 is a monster of a chip. 12 cores running at 2.7GHz base clocks and 30MB of L3 cache all running within a 130w TDP. The shrink to a 22nm process yields significant results. In many ways this chip is similar to the Sandy Bridge generation Intel Xeon E5-2680, except the die shrink allows for 50% more cores and cache. Intel also increases the price significantly and rumor has it that these chips will sell for just shy of $3,000 each. Let’s see how the processo

What is an optical module

What is an optical module: Optical Module (Optical Module), as an important part of optical fiber communication, is an optoelectronic device that realizes the functions of photoelectric conversion and electro-optical conversion.   To be precise, the optical module is a collective name for several types of modules, including: optical transmitting module Transmitter, optical receiving module Receiver, optical transceiver integrated module Transceiver and optical forwarding module Transponder. Generally, what we call optical module generally refers to an integrated optical transceiver module (the same below).   optical module   working principle: The optical module works at the physical layer of the OSI model and is one of the core components in the optical fiber communication system. It is mainly composed of optoelectronic devices (optical transmitters, optical receivers), functional circuits and optical (electrical) interfaces. Its main function is to realize the photoelectric conversio
