Block Storage Management For Containers
With native integration to Kubernetes, LINSTOR® makes building, running, and controlling block storage simple. LINSTOR is open-source software designed to manage block storage devices for large Linux server clusters. Its enterprise subscription LINBIT SDS, which includes DRBD, LINSTOR & Expert Support, is used for providing persistent Linux block storage for Kubernetes, OpenStack, OpenNebula, and OpenShift environments.

How does it work?
Controller, Satellite, and User Interface
The LINSTOR® system consists of multiple server and client components.
- A LINSTOR controller manages the configuration of the LINSTOR cluster and all of its managed storage resources.
- The LINSTOR satellite component manages creation, modification and deletion of storage resources on each node that provides or uses storage resources managed by LINSTOR.
- All communication between LINSTOR components uses LINSTOR’s own network protocol, based on TCP/IP network connections.
- The storage system can be managed by directly using a command line utility to interact with the active LINSTOR controller. Alternatively, users may integrate the LINSTOR system into the storage architecture of other software systems, such as Kubernetes.
- Seamless integration to various cloud environments with many additional software including Ha Controller, STORK, Kubectl Plugin, Operator
Fastest Persistent Storage
"LINSTOR's world record results prove we can speed up High Availability at a large scale without resorting to high-cost proprietary software stacks."
