## What it is
LINSTOR is LINBIT's open-source software-defined storage controller that manages replicated block storage volumes across Linux server clusters using DRBD, LVM, and ZFS. It natively integrates with Kubernetes (via CSI and operator), OpenStack, Proxmox VE, CloudStack, OpenNebula, OpenShift, and VMware to provide persistent, highly available storage.

## Use cases
- provide persistent volumes for Kubernetes clusters
- build highly available replicated block storage on Linux
- set up hyperconverged storage for Proxmox VE
- give OpenStack or OpenShift highly available block storage
- replicate volumes across nodes for disaster recovery
- manage ZFS and LVM storage devices across a cluster
- run HA databases like MariaDB on replicated storage

## When to choose
- you need replicated, highly available block storage for Kubernetes or OpenStack
- you run Proxmox VE or other hypervisors and want shared persistent storage
- you want software-defined storage built on DRBD with snapshots, LUKS, and NVMe support
- you manage large Linux clusters and need centralized storage orchestration

## When to avoid
- you only need single-node local storage without replication
- your environment is not Linux-based (LINSTOR targets Linux clusters)
- you need object storage rather than block storage
- you want a fully managed cloud storage service rather than self-hosted software
