产品详情资料
SATA的困扰
使用SATA硬盘现在***一时,因为相对价格较低。应用是作为企业磁盘到磁盘的近线存储与备份,但是现在,用户使用SATA硬盘来做主要数据在线存储的案例也比比皆是,其原因是因为可以节约***。SATA硬盘甚至成为了大型数据库的主要存储设备,其他以前使用FC硬盘的领域,现在也能看到SATA硬盘,显然用户对存储空间单位***极为关注,但似乎忽略了一些可靠性方面的问题。
好在现在RAID厂商已经开发了支持RAID-6控制器的SATA产品来打消这些疑虑,RAID6增加了***个独立的奇偶校验信息块,而不象RAID5只有一个校验块,所以可以同时允许两块硬盘出现故障。
但RAID6同时带来的是需要分配更多的磁盘空间,也需要在控制器和硬盘之间比RAID5提供更多的带宽。我们使用硬盘厂商希捷网站上提供的数据来做例证,750GB容量的SATA硬盘平均传输速度是78MB/秒,如果你用的RAID5时,你需要702MB/秒的传输速度让RAID集正常工作,但如果你用的是RAID6,平均速度至少要达到780MB/秒,或者提供10%额外的带宽。同样的速度问题在需要大量读写操作的应用软件中也存在,包括视频、音频输入输出流。还有一个可能被大家忽视的应用,那就是数据库重建索引。
毫无疑问SATA硬盘提供了一个较低的单位存储空间***,但是由于与FC硬盘相比每秒输入输出次数更少,而且指标都比FC硬盘稍逊一筹,比特误码率,硬盘转速以及较长搜索时间,企业究竟决定购买何种硬盘,显然还需要考虑更多地因素。
性能对连接组件的需求
当我们想要获得所需要的性能时,我们还需要做哪些投入呢?
假设需要建设满足性能要求的输入输出流的环境,需要每秒以MB或GB计算的传输速率,我们配备以下的硬件。

The troubles of SATA
The use of SATA hard drives is now * * * temporary due to their relatively low price. The application serves as a near-line storage and backup for enterprise disk to disk, but nowadays, there are also many cases where users use SATA hard drives for primary data online storage, because it can save * * *. SATA hard drives have even become the main storage device for large databases. In other fields that used to use FC hard drives, SATA hard drives can now be seen. Obviously, users are extremely concerned about storage space units, but it seems to have overlooked some reliability issues.
Fortunately, RAID manufacturers have now developed SATA products that support RAID-6 controllers to dispel these concerns. RAID6 has added * * * independent parity information blocks, unlike RAID5, which only has one parity block, allowing two hard drives to fail simultaneously.
But RAID6 also brings with it the need to allocate more disk space and provide more bandwidth between the controller and hard drive than RAID5. We use the data provided on the hard drive manufacturer Seagate's website as an example. The average transfer speed of a 750GB SATA hard drive is 78MB/s. If you are using RAID5, you need a transfer speed of 702MB/s to make the RAID set work properly, but if you are using RAID6, the average speed should reach at least 780MB/s, or provide 10% additional bandwidth. The same speed issue also exists in applications that require a large amount of read and write operations, including video and audio input/output streams. Another application that may be overlooked is database indexing.
There is no doubt that SATA hard drives provide a lower unit of storage space * * *, but due to fewer input and output times per second compared to FC hard drives, and various indicators slightly inferior to FC hard drives, bit error rate, hard drive speed, and longer search time, enterprises need to consider more factors when deciding which hard drive to purchase.
Performance requirements for connecting components
What additional investments do we need to make when we want to achieve the required performance?
Assuming that we need to build an environment with input and output streams that meet certain performance requirements and require a transmission rate in MB or GB per second, we must be equipped with the following hardware.
