vSphere Availability

May 11, 2024 3 minute read

vSphere Availability, also known as High Availability (HA), ensures that virtual machines (VMs) can automatically restart on another host if the primary host fails. This helps minimize downtime and data loss in the event of hardware failures or unplanned maintenance. vSphere HA provides continuous availability for mission-critical applications, such as databases, web servers, and file servers, by ensuring that VMs are always up and running.

Understanding vSphere Availability

vSphere HA works by monitoring the health of ESXi hosts in a cluster. If a host fails, vSphere HA automatically restarts the VMs that were running on that host on another available host. This process is transparent to users and applications, ensuring minimal disruption during failover.
