Linbit specializes in open source, software defined storage solutions using Linux operating systems. They provide the world's leading software defined storage solution for replicated block storage called DRBD, which is supported by their proprietary products and services. DRBD allows for high availability, disaster recovery, and private cloud solutions using common off-the-shelf hardware at a lower cost than traditional proprietary storage options.

DRBD’s use cases – Cloud, High Availability and Geo Clustering
The principal goal of a high
availability solution is to minimize
or mitigate the impact of
downtime
DRBD seamlessly replicates
data transparent to your
applications and databases,
eliminating single points of
failure within your IT infrastructure
High
Availabilit
y
The principal goal of disaster
recovery is to restore your
systems and data to a previous
acceptable state in the event of a
failure/loss of a data center
DRBD can mirror data
asynchronously over long
distances, forming an important building
block of your disaster recovery plan.
Geo-Clustering with automatic
fail-over is possible

Storage is one of the most critical
components in any cloud
environment It has to be easy to
provision, highly reliable, cost
effective and ideally running on
commodity hardware
DRBD9 is in OpenStack, so it integrates
seamlessly with your Private Cloud
Environment and runs on commodity
hardware, other cloud OSs and
virtualization platforms .

DRBD SDS is reliable block storage for OpenStack
OpenStack comes with a Cinder driver for DRBD SDS as of
the Liberty release (October 2015). This enables OpenStack users
to base their Cloud Instances' storage needs on DRBD SDS
By aligning allocations in Cinder and Nova hyper-converged
setups, we can archive storage access latencies of local storage,
for highly available block storage
DRBD9 adds Geo clustering functionality to Openstack
for the first time without purchasing proprietary hardware
With DRBD SDS solution common-off-the-shelf cloud hardware is turned into high-performance block
storage that scales horizontally to an unlimited number of nodes.
