About LINSTOR
LINSTOR is an open-source software-defined storage (SDS) management tool. It is used to manage block storage resources, particularly DRBD replicated storage, to provide high availability and disaster recovery for applications in Linux clusters.
LINSTOR is an open-source software-defined storage (SDS) management solution from LINBIT, designed to orchestrate block storage for Linux clusters. It specializes in managing DRBD (Distributed Replicated Block Device) resources to deliver high availability, disaster recovery, and high-performance storage. The software integrates natively with container platforms like Kubernetes and OpenShift via a CSI driver, and also supports virtualization platforms such as Proxmox VE, OpenNebula, and CloudStack. Key capabilities include a high-availability controller, separation of data and control planes for non-disruptive management, thin provisioning, and snapshot-based disaster recovery. LINSTOR is aimed at DevOps engineers and system administrators managing critical data in virtualized, containerized, or bare-metal environments. While the core software is open source, LINBIT offers commercial support subscriptions (LINBIT SDS) which include enterprise features and expert support.
Pros & Cons
- Open-source software with a strong focus on community and transparent development.
- Provides high availability and disaster recovery for block storage through DRBD replication.
- Native integration with Kubernetes, OpenShift, and other cloud orchestration platforms.
- Separates data and control planes, allowing for cluster management without service disruption.
- Supports hyper-converged infrastructure, reducing hardware costs and complexity.
- Pricing is not publicly listed and requires a quote, making it difficult to estimate costs.
- While there is community support, enterprise-level features and dedicated support require a paid subscription.
- The feature set is extensive and may present a steep learning curve for new users.
Features
Key features
Manages a large number of DRBD replicated storage resources to ensure high availability and performance.
Provides a container storage interface (CSI) driver for native integration with Kubernetes and OpenShift.
Features an HA controller and replication link to ensure data is always available and secure.
Allows for cluster upgrades and management without disruption to storage provided to applications.
Ideal for managing storage in hyper-converged VM workloads.
Supports instantaneous, copy-on-write (CoW) snapshots and clones of storage volumes.
Enables long-distance replication and backups to S3 and other targets by shipping encrypted snapshots.
Additional features
