Twice the 8GFC Emulex LPe16000 accelerate cloud computing

Recently, Emulex company launched the 9th generation Fibre Channel adapter LPe16000. The new Lpe16000hba is the industry's first 4-Port fused fiber architecture controller, which supports network integration of Gigabit Ethernet, 16GB FC, and maximum 40GB ethernet. The processing speed of more than 1 million I/O (IOPS) per second is supported on a single port, delivering high-performance I/O for high-density mission-critical cloud data centers and virtualized data centers.

As the volume of global data continues to surge, since the widespread popularization of intelligent mobile terminals, the unstructured data, including sound, picture and video, have brought great challenges to the data center storage system, which is based on the emergence of new technologies such as virtualization, cloud computing and so on. The Emulex company launched the LPE16000 network adapter to "accelerate" the cloud data center and the virtualized Datacenter Network.

Emulex LPe16000 Series Network adapters

Shaun Walsh, vice president of marketing at Emulex, believes the 16GFC ecosystem is rapidly maturing with the launch of Emulex 16GFC HBAs, 16GFC switches and 16GFC arrays to be launched in 2012. Buy 16GFC Storage infrastructure devices now for effective investment protection, higher performance-even in a 8GFC environment-and a variety of key features for improved virtualization, management, energy efficiency, and data protection. Applications that benefit from 16GFC technology include online transaction processing databases, data warehousing, and backup/recovery applications in traditional and virtualized cloud deployment environments.

Shaun Walsh said: "The LPe16000 series adapters provide more than 1 million iops of processing speed on a single port, delivering high-performance I/O to high-density mission-critical cloud data centers and virtualized data centers. This adapter brings not only a further increase in fibre Channel speed, but another designed to support next-generation cloud and virtualized environments with our Vscale programmable ASIC technology, virtual machine scalability, higher quality of service, data integrity, and performance management features. ”

LPE16000 Series HBA Performance resolution

Emulex Company in the relevant specifications of the data, we found that LPe16000 is actually running at 14.025gbp/s baud rate, while the 8G FC is the 8.5gbp/s baud rate, if calculated according to this value, 16G FC theory is slower. In this regard, Shaun Walsh explained to us that the previous product speed design uses the 8b/10b coding mechanism, which means that every 10 bits through the transmission cable, only 8 bits are data, while the other 2 bits are used to ensure the correctness of the data, so only 80% of the bits are transmitted data.

Emulex Company's 16G FC HBA at the beginning of the design of the coding mechanism used for the 64b/66b mechanism, and the use of 8B/10B encoding mechanism to transmit the same data, the transmission of the bit will be greatly increased. The use of 64b/66b mechanism can reduce the waste of bits and ensure the consistency of data transmission. Because of the high efficiency of the data it transmits, the link speed of the 16G FC enables it to provide data twice times the size of 8G FC.

According to Emulex's test data, the new LPe16002 HBAs can reach 1576 MB/s for the previous generation of 8G FC LPe12002 HBAs 789 MB/s. At the same time, the performance of the LPE16002 adapter with a 8-core processor is nearly 5 times times that of the previous adapter.

According to Shaun Walsh, LPe16002 's 8-core processor makes its single port ioPS more than 1 million. In addition, when the data size is not too large, it can also handle millions of I/O processing instructions, and this is the performance of the HBA processor, not the link rate, even if the use of 8G FC, the ioPS of the HBA can reach 1 million.

It is learned that the LPE16000 series adapter has built-in Vpath, Vscale, vengine components to provide the required performance, scalability, and security for the cloud and virtualized environments. The Greenstate power Management component supports selective dynamic hibernation, advanced cooling, and power management capabilities. Again assume that the integration advantages of ports and cables can provide three times times the energy efficiency of previous generations of products.
