Vxrail with SRM

Hello,

I have a generic question about Vxrail.

We are about to setup Vxrail with SRM to DR site.

In this implementation do we need to setup 2 x vxrail managers, 1 to each site or 1 vxrail manager that will manage both sites ?

Will the setup treated as 2 standalone Vxrail clusters and then setup SRM to connect them ?
