Data Director provides High Availability (HA) functionality through vSphere, and uses vSphere HA and vSphere DRS.

vSphere HA provides high availability for applications running in virtual machines. In the event of physical server failure, affected virtual machines restart on other production servers with spare capacity. In the event of operating system or database failure, vSphere HA restarts the affected virtual machine on the same physical server.

When you prepare a vSphere cluster for Data Director to use, you must enable vSphere HA and vSphere DRS. Data Director can take advantage of vSphere HA and vSphere DRS functionality because Data Director runs on top of the vSphere cluster.

See the vSphere Availability and the vSphere Resource Management documentation for information about creating clusters with vSphere HA and vSphere DRS.

See Managing Data Director Resources for information about creating resource pools that support HA and DRS.
