LINSTOR is an open-source storage controller for Linux building blocks: NVMe, NVMe-over-Fabric (NVMe-oF), DRBD, LVM, ZFS, VDO, MD-Raid, loop-devices, XFS, ext4 etc. The LINSTOR controller also includes CSI and K8s FlexVolume drivers.

LINSTOR is unique in that it is well-suited for I/O intensive workloads such as Databases, machine learning, and messaging; and it can run in either a Hyper-Converged Infrastructure (HCI), and Disaggregated Storage mode. LINSTOR delivers high IOPs while being composed of smaller, self-contained, extremely stable software; as compared to some of the newer storage options for Kubernetes which have highly developed control planes, but less-than-stellar data-planes. (IE: alternatives are less performant, in comparison).

With the Piraeus effort (, we provide an easily consumable set of container images which includes the DRBD linux kernel driver loader, linstor controller, linstor node software, CSI driver, and K8s-Operator.
