High Availability and Replication 13
Data Director provides High Availability (HA) functionality through vSphere and uses vSphere HA and
vSphere DRS functionality. Replication, which is the sharing of data between redundant resources to improve
reliability, fault-tolerance, and accessibility, is available for vPostgres databases.

You can replicate vPostgres databases to improve reliability, fault tolerance, and accessibility if a database
instance fails, or otherwise becomes unavailable.
About High Availability in Data Director
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.

and DRS.
