How to migrate manually created resources to LINSTOR

In many cases, existing DRBD resources that were created manually some time in the past can be migrated, so that LINSTOR can be used to manage those resources afterwards. While resources managed by LINSTOR can coexist with resources that were created manually, it can often make sense to migrate such existing resources. When resources are […]

The advantage of separate control and data planes

Many storage systems have a monolithic design that combines the control plane and the data plane into a single application and a single protocol, but LINBIT’s more modular solution comes with a number of advantages. What is a control plane or a data plane? The most important task that any storage system must perform is providing […]

The Technology Inside LINSTOR (Part II)

In our first look into LINSTOR you learned a lot about the single communication protocol, transaction-safety and modularity features. In the next chapter you can dive deeper into the construction. Fault Tolerance Keeping the software responsive is one of the more difficult problems that we have to deal with in LINSTOR’s design and implementation. The […]

The technology inside LINSTOR (Part I)

Spotlight on LINSTOR’s design and technology: What we do and how we do it to create a powerful, flexible and robust storage cluster management software LINSTOR is an application that is typically integrated with highly automated systems, such as software defined storage systems or virtualization environments. Users often interact with the management interface of some […]

Cluster-wide management of replicated storage with LINSTOR

The new generation of LINBIT’s storage management system focuses on ease-of-use, resilience and scalability. Todays IT installations often consist of many individual servers, each running some part of the software infrastructure that together form the kind of service that the installation is supposed to provide. Software processes rely on data, and high availability or disaster […]
