SolarWinds recommends hosting DPA in a virtualized infrastructure. Virtual hosting increases hardware fault tolerance and makes the DPA deployment less dependent on physical hardware.
If you have a cluster environment, you can configure DPA for continuous monitoring during an outage or failover.
The diagram below depicts a SQL Server Active/Passive Cluster housing the DPA repository:
To implement DPA in this configuration:
With Oracle RAC, the above DPA software configuration can be used if the Cluster shares disks to house the DPA software. Since all nodes are active in an Oracle RAC configuration, you should configure DPA to use the 'Shared or Load Balanced' connect string to the Repository.
