How It Works

LINBIT SDS combines LINSTOR and DRBD open source software to provide high availability, scalability, and storage cluster management. DRBD offers efficient replication for high availability, especially for small-write-intensive workloads like databases and messaging queues.

LINSTOR, the SDS component, allows for abstracting physical storage, creating logical storage groupings, and deploying a large number of storage volumes easily. It seamlessly works with DRBD-enabled devices, facilitating automatic storage volume deployment to meet replication and node placement requirements.

A LINSTOR cluster consists of a management plane with controller and satellite services and a data plane with storage layers like DRBD. The controller handles storage configurations, while satellite services manage block storage within host systems.

The separate management and data planes enable satellite nodes to provide provisioned storage independently, even when the controller or satellite services are not running during updates or maintenance.
