OpenStack Conference

Ceph is a massively scalable, distributed, unified storage system. This platform delivers object storage, block storage and a POSIX compatible file system that is easily deployed on commodity hardware. It is the only storage solution that is included in the Linux kernel and it provides a gateway that delivers S3 compatibility.

Ceph's Rados Block Device (RBD) integration with OpenStack delivers a highly scalable, shared, and reliable virtual hard disk solution.

• Highly Scalable - no block size limit
• Shared - accessible simultaneously from anywhere, making things like live VM migration possible
• Reliable - replicated, distributed, with no single point of failure
• Snapshots

This session will cover the current status of the integration, and discuss the technical implications and the advantages of block storage within the OpenStack cloud operating system.  For example, OpenStack Compute instances would benefit from Ceph block devices especially if the instances are running applications that require a database.

This advancement rounds out OpenStack storage offering and strengthens the position of the open source cloud operating system as an alternative to the AWS product line.
