Disk Type Selection EVS Performance EVS performance metrics include: IOPS: number of read/write operations performed by an EVS disk per second Throughput: amount of data read from and written into an EVS disk per second Read/write I/O latency: minimum interval between two consecutive
If the ECS has multiple EVS disks, the backup will be restored to the original EVS disk. Alternatively, you can specify another EVS disk for the restoration. The specified EVS disk must have an equal capacity to or a larger capacity than the original EVS disk.

(Optional) Installing the SDI Driver With the SDI driver, EVS disks can be attached to BMSs. The EVS disks can be used as system disks from which the BMSs are booted. This facilitates quick BMS provisioning.

VBS Functions You can use VBS to back up and restore EVS disks.

Currently, RDS calls the EVS APIs for encryption purposes. KMS is called when an EVS disk is created or mounted. Data writing and reading do not call KMS.
Buying HUAWEI CLOUD Products Procedure The following procedure shows how to buy an EVS disk: Go to the All Products page. Select Storage > Elastic Volume Service (EVS). Click Buy. Set the product information and click Next.
