Scaling VSG for a tenant

Does anyone know how having two VSGs servicing a single tenant affects the “Host Scalability” of 12 VEMs per VSG?

Per the docs each VSG can handle 12 VEMs.

I am understanding this as a single VSG module can service up to 12 VEM’s (Hosts). What if the customer has 13 hosts? Do you have to add another VSG?

I can’t find anything in any documentation on what the impact is of adding multiple VSG’s to a single tenant. How does that affect the 12 VEM per VSG limit?

Hi Bro

If I’m not mistaken, 16 virtual networks or tenants are supported in a Cisco VSG. Furthermore, Cisco VSG is offered as a virtual appliance, you can scale its deployment with the vPath architecture and by deploying more Cisco VSG appliances on demand, to cater to increase numbers of virtual networks /tenants.

P/S: if you think this comment is useful, please do rate them nicely 🙂

My concern isn't around virtual networks or tenants. It's the individual VSG's capability to handle host VEMs. Per the table below a single VSG can service 12 VEMs. What happens if the customer has vethernet port profiles attached to the vsg that are serviced by 13+ VEMs?

If you've more VEM's than a single VSG can handle, just add more VSGs.
