LINSTOR is an open source platform for managing block storage in distributed environments. It gives teams and organizations full control and makes automation easy to set up. Unlike proprietary storage tools, LINSTOR lets you manage your infrastructure exactly the way you want, without vendor lock-in or hidden limitations
LINSTOR runs on independent storage nodes that together form a cluster. Each node has its own rules for replication, backups and storage management. With DRBD (Distributed Replicated Block Device), data is replicated between nodes in real time. The combination of controllers and satellites allows the cluster to be managed centrally while keeping the storage flexible and distributed. This means you can use existing clusters, build your own, or add specialized nodes that fit perfectly into your environment.
With LINSTOR, you don't have to worry about managing storage manually. Creating, copying, and moving volumes happens automatically, which greatly reduces the chance of errors. It works well with backends like LVM, ZFS, or Ceph, even when resources are limited. You can also easily set up replication, create snapshots and run backups to keep your data safe and available.
Because LINSTOR is fully open source, your team can review, audit and improve the code while keeping complete control over how, where and when data is stored. The platform integrates smoothly with systems like Kubernetes, Proxmox and OpenStack and offers APIs and automation tools to fit easily into existing DevOps workflows. This makes LINSTOR not just a storage tool, but a flexible foundation for your entire IT infrastructure. At the same time, it encourages collaboration within the open source community, where best practices, improvements and integrations are shared without relying on hidden services or third-party restrictions.
