Features
The following is a list of the key features of VMware HA. For a comprehensive list of VMware Infrastructure features download the key features summary.
Key Features
- Automatic detection of server failures. VMware HA automates the monitoring of physical server availability. HA detects physical server failures and initiates the new virtual machine restart on a different physical server in the resource pool without human intervention.
- Automatic detection of operating system failures. VMware HA detects operating system failures within virtual machines by monitoring heartbeat information. If a failure is detected, the affected virtual machine is automatically restarted on the server.
- Smart failover of virtual machines to servers with best available resources (requires VMware DRS). Automate the optimal placement of virtual machines restarted after server failure.
- Scalable high availability across multiple physical servers. Supports up to 32 nodes in a cluster for high application availability.
- Resource checks. Ensure that capacity is always available in order to restart all virtual machines affected by server failure. HA continuously and intelligently monitors capacity utilization and reserves spare capacity to be able to restart virtual machines.
- Proactive monitoring and health checks. VMware HA helps VMware vSphere users identify abnormal configuration settings detected within HA clusters. The VMware vSphere client interface reports relevant health status and potential error conditions and suggested remediation steps.
- Enhanced isolation address response. Ensures reliability in confirming network failure by allowing multiple addresses to be pinged before declaring that a node is isolated in the cluster.
