High Availability: Linbit Merges DRBD+ with DRDB into Open Source
Austrian company Linbit has announced that it is merging its DRBD+ commercial high availability (HA) software with the open source version DRBD to make a free software solution.
The combination by Linbit of the two Distributed Replicated Block Device (DRBD) products will result in DRBD version 8.3, available under GPL and scheduled for release in December 2008.
Certain restrictions users had with the previous free version of the high availability cluster software will disappear. One restriction dashed is the previous limit of replication to 4-Tbyte devices. Other enhancements due to the merge include the ability to mirror data among three or four servers instead of just two, and the checksum resynchronization feature.
