API Overview

EVS APIs include custom APIs and Cinder APIs.

Custom APIs do not depend on OpenStack, and Cinder APIs depend on OpenStack. A combination of these two types of APIs allows you to use all EVS functions.

Table 1 API overview

Subtype

Description

EVS disk

You can use these APIs to create disks, delete disks, and query disk details.

EVS snapshot

An EVS snapshot is a complete copy or image of the disk data at a specific time point.

You can use these APIs to create snapshots, delete snapshots, roll back data from snapshots, and query snapshot details.

EVS recycle bin

If you enable the EVS recycle bin, EVS disks will be moved to the recycle bin upon deletion. This helps protect your disk data from accidental deletions.

You can use these APIs to query disks in the recycle bin and delete and recover disks from the bin.

EVS tag

Tags are used to identify the cloud resources for purposes of easy categorization and quick search.

You can use these APIs to add, delete, and query disk tags.

EVS disk action

You can use these APIs to expand disk capacities, reserve disks, export disk data as images, and set bootable flags for disks.

EVS disk transfer

Through disk transfer, you can transfer disks from one tenant to another. After a transfer succeeds, the ownership of the disk only belongs to the target tenant.

You can use these APIs to create, accept, delete, and query disk transfers.
