Storage is one of the critical parts of any cloud environment. It should be easy to provision, fully accessible and reliable as possible, the question is how do you do it without going out of pocket?

The Answer is to use commodity hardware with Open Source software to turn it into an affordable distributed network storage.

LINBIT bases its work in this area on the existing DRBD software, which got included into the upstream Linux kernel as of version 2.6.33 (released 2010). DRBD has a proven track record and many deployments in high available systems on all major Linux distributions.

In order to address the Scale out needs and cover Disaster Recovery setups, a new major release of DRBD was developed: DRBD 9. Together with a new feature-rich core, a new management tool, called ´drbdmanage´, has been developed to facilitate storage cluster management by tightly integrating local storage (LVM) and management of the data replication (DRBD) across all nodes part of the storage pool. On top of this there is a cinder driver that binds the whole stack to the OpenStack world.

This stack can now deliver a reliable block storage with high-end IOPs and a complete integration into OpenStack. It can either use regular TCP/IP or RDMA, conventional spinning hard disks or high-speed SSDs, synchronous or asynchronous replication, works for local (within a data center) as for remote (disaster recovery) replication. Due to the high performance this stack delivers it is very well suited for database workloads (structured data) and workloads that require a conventional file system on a block device. This should not be confused with an object storage.
