OpenSSI Cluster integrated HA-LVS
Introduction
The OpenSSI project is a comprehensive clustering solution offering 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.
LVS has been integrated into OpenSSI with configuration support for multiple failover directors including inline load-balancing. OpenSSI HA-LVS currently supports DR and NAT LVS routing.
One really nice feature about HA-LVS is automatic detection of up/down TCP services for automatic IPVS tables management. Our development version also features automatic detection for UDP services.
