This article introduces the relevant knowledge of "What does Cloud Virtual Machine io mean?" In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

IO is a concept often mentioned in Cloud Virtual Machine disks. I/O (input/output) literally means input/output, input refers to writing data to disk, output refers to reading data from disk.

Disk IOPS (Input/Output per Second) is the number of I/O requests a disk can handle in one second. Storage performance is generally measured by throughput (transmission speed) and IOPS.

Throughput mainly refers to the continuous read and write speed of large files. It is applicable to scenarios such as copying and backup of large files. The throughput of disks can be tested by using the "benchmark" test function in HD Tune Professional Edition. The sequential read and write speed of traditional mechanical sata hard disks is 80~150M/s, SAS hard disks is 150~200M/s, and SSD solid state disks is 400~600M/s.

Elastic Cloud Virtual Machine: Sequential read speed of 100~300M/s under normal load and test speed of 400~700M/s under cluster no-load. Sequential writing speeds range from 30 to 70M/s.

In terms of storage, SAS and SATA disks are commonly used at present, and SSD disks are also used for some high-end storage, providing high-performance cloud disk and SSD ultra-high-speed cloud disk storage options for Cloud Virtual Machine users, and supporting users to choose according to their own application deployment requirements.

High-performance cloud disk: 4 copies of each data are retained, support hot migration, snapshot backup, etc., provide long-term stable I/O performance output, suitable for most business scenarios such as web services, small and medium-sized databases, and enterprise offices, and meet the I/O requirements of core business testing and development joint debugging environments.

SSD ultra-high-speed cloud disk: a distributed storage system using high-speed SSD hard disk, which combines all the advantages of high-performance cloud disk, and has extremely high random read and write IOPS and high throughput. It is suitable for core critical business systems with high load and intensive I/O requirements and supports large-scale database operation.
