Our  East Site - Installed and configured successfully
Windows Server 2022
SQL Server 2022 Always On Cluster (with Local HA)
WAS ND 9.0.5.24 - Cluster
2 CPE Nodes - Content Engine 5.6.0-3-41
2 ICN Nodes - 3.1

Now, we plan to install our Disaster Recover (DR) site in West site.
Our database cluster extends to both East and West using the pattern called Local HA, Remote DR, essentially -all are connected by same cluster and listener with 1 Primary (RW) and other 3 are standby (R).

In West, WebSphere Cluster is specific to West site. If we deploy 2 DR CPE nodes to this WAS ND Cluster using the same database connection - Would CPE recognize 2 CPE nodes from East and 2 CPEs from West.

Bottom line, since our HA and DR sites has single LocalHA/RemoteDR DB cluster, how do we install FileNet CPE in HA and DR? 
Option 1 - Separate Pairs of CPEs in each East and West sites with 2 WAS ND clusters in each site or
Option 2 - Create single WAS ND cluster for both CoLo East and CoLo West sites and deploy 4 CPE nodes to single cluster and keep DR CPE nodes in standby.
