Storage in DreamCompute is implemented with Ceph. Ceph is a massively scalable, distributed, redundant storage technology that can be delivered using standard server hardware. OpenStack’s Cinder project integrates with Ceph for block storage using Ceph’s RADOS Block Device (RBD) software.

Ceph is software created by DreamHost founder Sage Weil and has been under development inside DreamHost for several years. Ceph has been open source since its inception, and in early 2012, a new company called Inktank was spun out of DreamHost to support and continue development of the technology. Inktank was then acquired by Red Hat in April 2014.

Ceph is also the foundation for DreamHost’s cloud storage service DreamObjects.
