What is OpenSSI Clusters for Linux FOR LINUX?
OpenSSI Clusters for Linux for Linux
OpenSSI Clusters for Linux project is a comprehensive clustering solution offering a full, highly available SSI environment for Linux. The goals for OpenSSI Clusters include availability, scalability, and manageability, all built from standard servers.
Key Features:
- Membership: Courtesy of the ci project, includes libcluster and cluster command (part of tools).
- Internode Communication: Courtesy of the ci project.
- Filesystem: CFS is transparently stacked over any ext3 mount, making it instantly and coherently shared across the cluster.
- Process Management: Very complete, including clusterwide pids, process migration, and distributed functionalities.
- Devices: Clusterwide device model via the devfs code, making all devices visible and accessible from nodes.
- IPC: All IPC mechanisms are clusterwide, ensuring seamless communication object handling.
- Clusterwide TCP/IP: Integrated ha-lvs for efficient port redirection to servers in the cluster.
- Paging/Swapping: Each node operates independently for optimized performance.
Additional Features:
- Kernel Data Replication Service: Ensures data integrity and redundancy within the cluster.
- Shared Storage: Supports shared FCAL for HA-CFS usage.
- HA Interconnect: Bonding support for seamless communication.
- Sysadmin Services: Architecture has been made clusterwide for efficient management.
- Init, Booting, and Run Levels: Runs with a single init that ensures seamless failover and restart on another node.
