Collax V-Cube+ is a comprehensive server virtualization and high availability solution developed by Collax Inc., designed for small and medium-sized enterprises. It combines two Collax V-Cubes into a two-server cluster, providing redundancy, failover capabilities, and high availability for virtual machines. The system utilizes the open-source KVM (Kernel-based Virtual Machine) hypervisor for efficient hardware resource utilization. Collax V-Cube+ ensures application availability even if one server fails, as multiple virtual machines can run simultaneously on both nodes. The solution includes features like embedded SAN, proactive HA, live migration, and integrates with Collax Central for centralized management and monitoring.
