Re: ESRS Gateway and Policy Manager
Having one ESRS gateway server on each site is the normal method of achieving High Availability. They are logically clustered in the ESRS application, and run in an active-active manner. Both gateways are capable of handling communication with all the customer EMC devices. So each gateway needs to be able to "see" the EMC devices at both sites. If one gateway fails, all the activity is done by the remaining one.
