The Storage Connector nodes communicate with the Atmos storage backend via port 80. The Atmos storage environment consists of multiple nodes and any of which are capable of servicing requests from Storage Connectors. EMC suggests using a round robin algorithm on a load balancer. This results in even distribution of service requests across the Atmos nodes. The health of the Atmos environment can be tested using PING or by requesting the /rest page from the Atmos node.

A Virtual Service should be created on the LoadMaster interface which is connected to the particular Storage Connector subnet. This Virtual Service should accept HTTP requests on port 80 and balance them, using round robin, to the Atmos nodes (the six IP addresses on 10.1.1.0/24 in this example).

Atmos nodes are added as Real Servers with the server check set to ICMP Ping or HTTP Protocol. Using HTTP as the check protocol gives a view of the Atmos REST service status while PING only checks the host network status.
