Cloud Block Storage (RBD)

Cloud Block Storage provides persistent block-level storage volumes for use with I/O Cloud Compute instances. It is backed by Ceph RBD (RADOS Block Device).

Features

• Persistent Storage: Volumes persist independently of the life of an instance.
• Scalable: You can increase the size of volumes as needed.
• High Performance: Designed for high I/O performance suitable for databases and other intensive workloads.
• Snapshots: Take point-in-time snapshots of your volumes for backup and restoration.

Usage

Block storage volumes are primarily attached to Compute instances. You can format them with any filesystem (e.g., ext4, xfs) and mount them as you would a physical disk.
