Dual ESRS Gateway server in single site

Hi

We have Unity All Flash (450F) & powermax arrays in one single site and need these to be managed by Centralized ESRS Gateway servers.

We are planning to have 2 dedicated VM's in the same site to act as Centralized ESRS Gateway servers - Believe this will be called as HA Dual ESRS Gateway servers (within same site) - 2 GW servers will be clustered in EMC ESRS infra.

I came across below statement with respect to Unity arrays in one of the Unity ESRS Guide :

The Centralized ESRS option in Unity does not support HA. This option does not provide a failover capability to an active HA ESRS VE Cluster. When the storage system is deployed to a single HA ESRS VE Gateway cluster server (the only configuration option available), there is no failover capability to the surviving HA ESRS VE Gateway server in the cluster. If the HA ESRS VE Gateway server to which the storage system is connected goes down, the storage system will stop transferring any outbound files, such as call home and CloudIQ files, to the Service Center. ESRS inbound connectivity (remote access) to the storage system will still function using the surviving HA ESRS VE Gateway server in the cluster.

Does this mean Unity will not work in the setup that I stated - 2 dedicated VM's in the same site to act as Centralized ESRS Gateway servers

(OR)

Does it mean Unity will not failover from Dual ESRS servers in Site A and Dual ESRS servers in Site B  - so 2 in site A + 2 in site B ?
