Compute High Availability

ZSphere uses KVM-based hardware virtualization to pool a group of physical servers and manage them as clusters. ZSphere continuously monitors the operating status of every host and VM in a cluster. When a host fails, the ZSphere management node confirms that the host is unavailable and restarts the affected VMs on another host in the cluster to maintain service continuity. ZSphere compute high availability requires no dedicated standby hardware or third-party failover software, reducing downtime and service interruption without the cost and complexity of operating-system-specific or application-specific failover solutions.
