Hello Community,
In VM Networking, when I created a Vmware domain, a Vswitch Policy (DVS), added a controller, ACI then created a DVS switch. VM team requests to create two DVSwitches one for each Data Center per vCenter. Is it possible?
Thanks,
Trinh Nguyen

Hey Trinh,
Yes you can deploy multiple DVSwitches in the same vCenter, you will just need to create another vCenter domain in ACI. The name of the DVS is derived from the name of the vCenter domain.
In your case, let's say you have vCenter A, DC1, and DC2. Create a vCenter domain in ACI named DVS1 using vCenterA and DC1. DVS1 will then be created and pushed to vCenter A under DC1. Create another vCenter domain in ACI named DVS2 using vCenterA and DC2. DVS2 will then be created and pushed to vCenter A under DC2. Is that what you were looking for/asking?
While the scalability guide lists two datacenters in vCenter as a limit, you can have 200 vDS deployed. The guide also relies upon all the maximum numbers being hit (vDS, VMM instances, EPG's, endpoints, etc). For example, I have 5 datacenters deployed in my lab vCenter, but I don't have that many VM's deployed in each so it isn't an issue. The recommendation is to follow the limits outlined in the scalabilit guide for a production fabric
Hope this helps!

Hello Trinh,
From a technical perspective, it should be possible. From a scalability perspective, it looks like numbers on 2.3 indicate that we only support up to 2 Datacenters per vCenter on a fabric scale:
From the ACI Scalability Guide for version 2.3:
VMM Scalability Limits
Configurable Options | Per Leaf Scale | Per Fabric Scale |
Datacenters in a vCenter | N/A | 2 |

Russ,
That is what I am looking for! Many thanks.
