API Overview

EVS APIs include APIs and OpenStack Cinder APIs.

A combination of these two types of APIs allows you to use all EVS functions.

API

EVS disk

These APIs provide the functions, such as creating disks, deleting disks, and querying disk details.

EVS snapshot

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

These APIs provide the function of rolling back the snapshot data to the disk.

EVS tag

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

These APIs provide the functions, such as adding, deleting, and querying tags.

OpenStack Cinder API

EVS disk

These APIs provide the functions, such as creating disks, updating disks, querying disks, querying images, and querying quotas.

EVS disk action

These APIs provide the functions, such as expanding disks, reserving disks, exporting disk data as images, and setting the bootable attribute for disks.

EVS snapshot

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

These APIs provide the functions, such as creating snapshots, querying snapshots, updating snapshot metadata, and querying snapshot metadata.

EVS disk transfer

Through the disk transfer function, disks can be transferred from one tenant to another. After the transfer succeeds, the ownerships of the disks belong to the target tenant only.

These APIs provide the functions, such as creating, accepting, deleting, and querying disk transfers.
