Which feature is designed to protect VMs from hardware failures in vSphere?

In the context of protecting virtual machines (VMs) from hardware failures within vSphere, the most relevant feature is vSphere High Availability (HA). vSphere HA is specifically designed to automatically detect hardware failures and restart the affected VMs on other available hosts within the cluster. This ensures minimal downtime and maintains service availability in the face of hardware issues.

When a host fails, HA initiates a failover process that involves restarting each affected VM on other hosts that are part of the cluster, which is crucial for maintaining business continuity. The automatic nature of this process helps in quickly recovering from failures without requiring any manual intervention, thereby enhancing operational resilience.

While vSphere Fault Tolerance, Storage DRS, and VMware VSAN also play important roles in the VMware ecosystem, their primary functionalities differ. For example, vSphere Fault Tolerance provides continuous availability by creating a live shadow instance of a VM, allowing it to run concurrently with the primary VM without downtime, but this is a different approach compared to the failover model of HA. Storage DRS optimizes VM storage resources and provides load balancing for storage, while VMware VSAN focuses on storage solutions that can be integrated within a vSphere environment. However, none of these features are specifically designed for responding
