EVS provides you with high-performance, persistent block storage. You can use the EVS to create disks and attach them to ECSs so that the ECSs can access and use the disks.
EVS provides the following features:
- Supports different types of EVS disks, including those providing common I/O, high I/O, and ultra-high I/O. You can select the EVS disks based on your requirements for I/O.
- Allows you to expand the EVS disk capacity elastically to meet the increasing requirements for storage capacity.
- Provides ultra-large storage capacity. A single EVS disk supports up to 32 TB of space.
- Work with VBS to provide the backup service and restores data in the event of an exception, for example, the misoperation, attack, or data tampering.
