Block Storage Volume that Provides Distributed Storage Space for Elastic Baremetal Instances

In previous version, you need to deploy a distributed storage and add it to ZStack Cloud before you can allocate the distributed storage space to elastic baremetal instances through gateway nodes.

Starting from 4.7.21, you can create and manage block storage volume on ZStack Cloud directly with a distributed storage access token. The block storage volume can be allocated to elastic baremetal instance as needed. In addition, you can configure multi-path access for these block storage volume to achieve high availability of I/O access paths and ensure business continuity. One elastic baremetal instance can be attached with 1-255 block storage volumes, and a block storage volume can be attached to 1-16 elastic baremetal instances.

Management of Block Storage Volume Lifecycle and Snapshot

ZStack Cloud provides basic lifecycle management for block storage volumes, including creation, edition, deletion, maximum/burst IOPS setting, maximum/burst bandwidth setting, expansion, and attachment/detachment to/from elastic baremetal instances. Meanwhile, ZStack Cloud allows you to create snapshots based on block storage volumes to ensure the data security.
