DRBD is an established building block for MySQL high availability database clusters. It has been included in the MySQL Enterprise offering since 2007. DRBD provides transaction-safe, synchronous, shared nothing block-level replication—and as such, has one drawback: it introduces additional write latency. With traditional IP/Ethernet-based replication, in the past this made DRBD a less than optimal choice for database environments with high write loads, or those with requirements for very low write latency.
Recent DRBD versions introduced support for Dolphin Express
interconnects as a replication transport for DRBD. By using low-latency Dolphin Express interconnects, DRBD can now leverage highly efficient Dolphin SuperSockets as its replication transport, dramatically cutting down on write latency.
With DRBD 8.3, MySQL on DRBD now also supports fully transaction-safe,
synchronous storage replication across up to four nodes.
