OpenStack Block Storage Service is a block-level storage solution that allows customers to mount drives or volumes to their OpenStack Compute servers™. The two primary use cases are (1) to allow customers to scale their storage independently from their compute resources, and (2) to allow customers to utilize high performance storage to serve database or I/O-intensive applications.
Interactions with Block Storage occur programmatically via the Block Storage API as described in this Developer Guide.
Highlights of OpenStack Block Storage Service include:
Mount a drive to a Compute server to scale storage without paying for more compute capability.
