OpenSSI Cluster integrated HA-LVS
From LVSKB
Introduction
The SSI project leverages HP NonStop Clusters for Unixware and various open source technologies to provide a full, highly-available SSI (Single System Image) clustering environment for Linux. Goals include availability, scalability and manageability.
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.
