Open Source

For the community, from the community.

Shared-Nothing Architecture

Eliminating single points of failure.

Wide Linux Distro Support

RHEL, Ubuntu, Rocky, Alma, Debian, SLES, and so on.

Low CPU & Memory Consumption

Leaving system resources available for your applications.

Low Recovery Time Objective (RTO)

Configurable monitoring intervals  means faster  recovery from host and application-level failures.

Application Agnostic Cluster Framework

Supports any application through the open cluster framework (OCF)

Commercial Off-the-Shelf (COTS) Hardware

Support for hardware of any class (x86_64, aarch64, ppc64le, and s390x CPU architectures; HDD, SSD, and NVMe block storage).


Infiniband , RDMA and 10/40/56/100 Gbit Еthernet support.

High Performance  In-Kernel Data Replication

Up to 32 replicas per DRBD virtual block device.

Network Redundancy and Load Balancing

Network redundancy for replication when using  TCP/IP. With RDMA, load balancing is possible.

TRIM or Discard Support

Trim or Discard support for SSD backed DRBD devices means write performance will not degrade over time. 

Three Types of Replication

Synchronous, asynchronous, and semi-synchronous replication modes.
