When configuring IP connectivity between Converged Systems, you must validate IP connectivity
between the two VMware vSphere 6.5U1 vcesys_esx_mgmt VLANs and verify that all required protocols
and ports are allowed on any firewalls between the two vcesys_esx_mgmt VLANs.
Refer to the following VMware KB article for additional information with VMware vSphere 6.5U1:
All local and remote ELM with VMware vSphere 6.5U1 components require DNS and NTP support.

VMware ELM conclusions (vSphere 6.5U1)
The following are the conclusions for VMware ELM with vSphere 6.5U1.
Enhanced Linked Mode with VMware vSphere 6.5U1 provides single pane of glass management for up to
10 PSCs and 15 VMware vCenters in a Single Sign-On Domain. This provides an operational
improvement in managing multiple VMware vCenter servers. However, as the number of PSCs and
VMware vCenter servers increases, the size of the VMware vSphere 6.5U1 fault domain becomes larger.
Processes to backup and restore any VMware vSphere component participating in ELM must be
absolutely reliable and supportable across Converged Systems and data centers. Maintaining
synchronization of PSC replication requires 100% network availability between PSCs in different
Converged Systems or data centers. After a PSC outage, synchronization may take some time to occur.
In addition, as the size of the SSO Sign-On domain increases, maintenance updates require more
planning and coordination, because VMware build numbers must be consistent in an ELM with VMware
vSphere 6.5U1 configuration. Upgrading any Converged System in an ELM with VMware vSphere 6.5U1
configuration also requires a corresponding upgrade for any other Converged Systems joined to the same
VMware vSphere 6.5U1 Single Sign-On domain. Upgrades are usually performed in a maintenance
window with time allocated to install, verify and, if necessary, back out the upgrade. Although a VMware
vSphere 6.5U1 Single Sign-On domain can be large, the Dell EMC approach for ELM with VMware
vSphere 6.5U1 deployments takes into account the increased complexity for backup and recovery and
RCM upgrades. Dell EMC recommends the deployment of the AMP-2S for large SSO domains. The
following table summarizes ELM with VMware vSphere 6.5U1 scalability and the AMP-2S.
