BGDSAN + Distributed Replicated Block Device (DRBD®)
A Low-Cost, High Availability Solution for Redundancy
Beechglen BGDSAN‘s leverage DRBD to provide a clustered, High Availability solution for legacy HP3000 and HP9000 servers. A BGDSAN™ with DRBD® is a low-cost alternative to expensive redundant SANs. DRBD synchronizes operating system files and user data alike to a secondary BGDSAN to maintain an up to date back up server available at a moments notice. A BGDSAN with DRDB provides peace of mind that upon a hardware failure there is a working copy ready to go. DRBD has little overhead and no impact to the production server as it operates efficiently and directly between the replicating BGDSANs.
- DRBD replicates data in real time. Replication occurs continuously, while applications modify the data on the BGDSAN.
- DRBD transparently replicates data. The host servers and their applications using the BGDSANs are oblivious to the fact that the data is stored on several storage devices.
- DRBD can be understood as network based RAID-1.
