2 vCenter ELM and NSX 4.0 Manager Clusters

jeremystanley — Wed, 16 Nov 2022 17:20:50 GMT

The 2 environments we are going to be implementing NSX in are currently in ELM. Planning on deploying NSX 4.0.1.1.
Is it required to have only a single management cluster to cover both vCenters, or can we still deploy a management cluster for each site?

The sites are geographically separate and the ELM was only implemented to provide the whole single pane of glass. They are still 2 disparate sites that operate autonomously.

Our NSX implementation will be using VLAN backed segments, and at this time we no intention of implementing overlay.

Documentation related to ELM with NSX is extremely limited, or at least difficult to find. While I have found the documentation related to multi-site, this does not fit our use-case.

Hi,

You can have both vCenters added to a single NSX Manager as Compute Managers if the RTT between the NSX Manager in one site & ESXi hosts (Transport nodes) on the other site is less then 150 ms. The other option is to have individual NSX Manager instances at each site.

Can we have a segment spanning between both vCenter with this configuration ?

Yes as long as you connect them to the same transport zones. What you are looking to do is multi-site NSX. It has some limitations so have a read and make sure it's the right fit for you
