DRBD is a block-based data replication solution available and well known since a couple of years. DRBD is designed to turn ready available applications into highly-available applications without the need for SAN infrastructure. In fact DRBD can be used to build high available storage-heads for IP-based, replicated SANs and long distance data replication.

Until today DRBD had a limitation to two nodes in principle. With DRBD9 a new release is in preparation (release candidate) which allows for the first time to do block based replication to up to 32 nodes. Out of the DRBD's features a number of deployment scenarios arise: HA-databases, file servers, block based storage targets, storage for a private cloud infrastructure and more.
