Can the cloud disk be used as a disk for the server? Many people do not understand, today Xiaobian in order to let you know more about the server disk, so give you a summary of the following content, let's look down. I'm sure you'll get something.

In the process of purchasing or using a CVM, we can often hear the concept of cloud disk and disk. In fact, the two are not the same thing.

1. About cloud disk

Take the cloud disk as an example, it can be used as a stand-alone hard disk to provide elastic, stable, reliable and low-latency persistent data storage services for elastic cloud servers. Cloud disks are mounted with elastic CVMs in the same cluster to achieve data storage and copy functions. A CVM can mount up to 10 cloud disks to meet users' big data storage needs.

two。 About disk

The concept often mentioned on disk is IO (input/output), which is input / output. Disk IOPS, that is, the number of Imax O requests that can be processed by the disk in one second. For applications with frequent random reads and writes, IOPS is the key indicator. Another important metric is data throughput (the amount of traffic per second of disk Imax O). Disk IOPS and throughput are dynamic, and the maximum theoretical value is affected by hardware. In actual testing, it is not only related to read and write load, but also can influence each other.

To put it simply, in the cloud server, the cloud disk is mainly used for data storage, while the disk is used for data reading and writing.

Provide CVM users with two storage options of high-performance cloud disk and SSD ultra-high-speed cloud disk, which can be selected according to their own application deployment requirements. Elastic CVM is located in a full 10 Gigabit cluster environment, with 10 Gigabit network interconnection in the private network, high-performance network architecture, low latency and high broadband. Enhance the disk IO performance, and then improve the random IOPS, packet processing capacity, disk network performance improved more than 10 times.

Therefore, CVM can satisfy both high-performance cloud disks and disks. Distributed cluster storage can fully disperse IO throughput and improve processing capacity.
