OpenSSI is a single-system image computer cluster solution for Linux.

The OpenSSI project leverages both HP s NonStop clusters for UnixWare technology and other open source technology to provide a full, highly available SSI environment for Linux. Goals for OpenSSI Clusters include availability, scalability and manageability, built from standard servers. Technology pieces include: membership, single root and single init, cluster filesystems and DLM, single process space and process migration, load leveling, single and shared IPC space, device space and networking space, and single management space.

The OpenSSI Clustering project leverages the Cluster Infrastructure (CI) for Linux project.
