Industry insiders expect SSDs to be universal

The SSD solid-state drive, with fast reading and energy saving as its main selling point, is no longer new on the PC. In the IDC Industry server area, the use of SSD solid-state hard disk deployment is not much, after all, the IDC industry server areas for storage and cost control requirements higher. However, the domestic has been the adoption of SSD hard disk set up by the cloud server and VPS host products. The progress of technology or help SSD break through a variety of obstacles, gradually in the server domain to be applied. Industry insiders predict that with the increase in the amount of SSD and SSD technology level, cost reduction, SSD will be popularized.

Solid-state drives appear to be an emerging thing in recent years, but companies have been using solid-state drives for about 25 years. The initial application of solid-state drives is limited to caching in real-time, high performance demand applications or military industrial applications (because the working environment is too harsh for standard hard drives). From the IDC point of view, SSD's biggest advantage comes from the read-write speed is very fast, up to 500m/seconds, and can quickly save data, SSD solid-state hard disk entire storage data transfer quickly, performance than traditional mechanical hard drive several times. The second is that SSD energy consumption is only about one-seventh of the HDD, for the room and telecommunications operators, then SSD replacement of the role and potential value of HDD is very large. Properly used, SSD can significantly reduce the disk array of power and cooling costs, electricity consumption can be reduced by 50%, scattered heat close to zero.

It is understood that the domestic well-known IDC enterprise Speed Cloud Host (www.vipiis.com) in the first since 2009 has been in its servers in the use of SSD hard disk. Speed Cloud host sales director Cao introduced, initially only in the server system disk and boot disk using SSD instead of the traditional mechanical hard disk, mainly in order to start fast, stable performance. After more than a year of pressure testing and commissioning, data stability, and has now begun to provide SSD products to customers, especially SSD solid state hard Drive VPS host, IO performance than traditional mechanical hard drive more than 400%, data read and write speed is very alarming. Cao said that the current use of SSD disk server cluster has also been to the market, but also to promote the addition of SSD cloud host and cloud space products to meet the needs of different customers.

At present, a 40GB SSD in the cost of roughly equivalent to 500GB of mechanical hard disk, because of high cost, SSD to completely replace the mechanical hard drive is not realistic, but in some special areas SSD still shows a very good market prospects. For example, in some high altitude areas, mechanical hard disk after a period of time can only read and cannot write, and SSD because there is no moving parts there is no such use restrictions. One more thing to say, with the development of cloud computing technology, the domestic major IDC are in the launch of cloud host products, due to the cloud server product characteristics, the general emergence of hard disk read speed is very slow problem, a large number of evaluation data shows Aliyun host and Sheng host hard disk IO speed is still not improved, The average read and write speed is only dozens of m per second, far less than the traditional stand-alone server performance, and even can not run large programs and databases, and SSD solid state hard disk can make up for this regret.

Speed cloud host belongs to the rapid power of the IDC Business Department, nine years of IDC operational experience, based on a number of brands of Dell PowerVault md3200i cluster storage devices and dozens of Dell R620 servers, using Enterprise-class SSD hard disk and Cachecade technology, Create a burst IO Performance Cloud host products. The latest Intel Xeon E5 series CPU, performance improvement of more than 80%! With regard to the reliability of SSD, Mr. Cao said that with the support of the mechanical hard drive to read its own state through the software (such as the smart features of the hard drive), each SSD manufacturer also has similar software to match the use of SSDs. This software, in addition to monitoring the use of hard disks like smart, can also estimate the life of the hard drive. In addition, for example, RAID technology in the fast Cloud host storage device also applies to SSDs, which can further secure the system and data.

Very high cost with a significant performance boost. This is the IDC industry Contrast Data Center in the use of solid-state disk and hard drive two conclusions. At present, due to high availability and price factors, the number of mainframe products using solid-state disk in the market is relatively limited. Solid-State drives allow enterprise users to deploy new applications or significantly improve the performance of existing systems. Despite many obstacles, many IDC companies have begun to deploy solid-state disk systems, although far from perfect, but the results proved to be very attractive. Because the cost of solid-state drives is too high, the author suggests that IDC companies do not have to deploy solid-state drives throughout their storage architecture.
