Fusion-io CEO: Interpreting the path of data center acceleration

Sina Weibo is one of the largest interactive social platforms in the country, compared with other Sina company's network business, the early peak of micro-blogging business comes earlier, the late peak lasts longer, and most importantly, the business pressure of Sina Weibo often has very fast and intense growth in a short time. Sina Private Cloud Platform System architect Chen Ledong introduced.

"For example, after a hot event, the number of visitors, fans will be in a very short period of time to break through the growth rate of 85%, or we have done 1-2 micro-interviews, the number of related fans will also have a very rapid growth, this sudden http://www.aliyun.com/ Zixun/aggregation/13999.html "> Workloads cause a lot of business pressure on the backend system. "Chen Ledong said that the Japanese earthquake as an example, caused by the background data written in 5 times times the usual growth, the overall visit is about 10-20 times the growth, and this sudden incident in fact, in China there are many.

To cope with this unexpected burst of workload, Sina Weibo selected the Fusion-io company based on the PCI interface of the flash card for the overall system speed, "we found that 10 Fusion-io card can meet all our access pressure and business needs, even in the spring Festival peak there is no problem , there is no complaint from any business unit. ”

Address the bottleneck of Sina Weibo system

Flash flash memory to improve the overall performance of the system can have an immediate effect, which is already well-known fact, however, to the flash application in the process there are differences in application mode, such as Sina, the use of the PCI interface based on the Flash memory card as a system speed scheme.

David A. Flynn, founder and CEO of ▲fusion-io, said in an interview with IT168 Editor: "We have the deepest understanding of the working mode of flash memory, and our solution is best able to take advantage of flash memory." ”

"The application of flash memory in SSD mode is actually a controller architecture to improve disk speed." However, the IO bottleneck caused by the controller architecture and disk performance cannot be solved at all. Although the storage performance can be improved by SSD, it is far from satisfying the purpose of increasing CPU usage. The most efficient way to improve data processing capability is to approach the CPU to solve the problem. Fusion-io combines high reliability flash technology with high intelligent software technology to raise data processing speeds to millisecond levels. This is a leap-forward performance improvement. ”
