Rackspace Cloud Block Storage API 1.0#
Last updated: Oct 21, 2019
Rackspace Cloud Block Storage enables customers to mount drives or volumes to their Rackspace Next Generation Cloud Servers™ and OnMetal™ Cloud Servers. The primary use cases for Cloud Block Storage are to enable you to perform the following tasks:
- Scale your storage independently from your compute resources.
- Use high performance storage to serve database or I/O-intensive applications.
Rackspace Cloud Block Storage provides the following offerings:
- The ability to mount a drive to a Cloud Server to scale storage without paying for more compute capability.
- A standard speed option at a low cost/gigabyte (GB) using SATA drives for customers who just need additional storage on their Cloud Server.
- A high performance option for databases and high performance applications, leveraging solid state drives (SSDs) for speed (at a higher cost/GB).
Cloud Block Storage is an add-on feature to Next Generation Cloud Servers and OnMetal Cloud Servers. Customers can not attach Cloud Block Storage volumes to other instances, like first generation Cloud Servers.
Cloud Block Storage is a multi-tenant rather than a dedicated service.
When volumes are destroyed, Rackspace keeps that disk space unavailable until zeros have been written to the space to ensure that data is not accessible by any other customers.
Cloud Block Storage allows you to create snapshots that you can save, list, and restore.
Cloud Block Storage is built on the OpenStack Cinder project. For more information about OpenStack Cinder, see the OpenStack Block Storage API v1 Reference.
