VXRAIL replication
for replication between two vxrails, do both appliances must be under same vCenter or different?
Also How much bandwidth required for replication between both appliances?

We have this logged with DellEMC at present around the supported config of the kernals and how it would be affected during an automated upgrade.
With regards to the bandwidth that all depends on data change/size or replication etc etc could go from 10 meg to 40 gig connections, latency though is always the biggest factor with I think 12ms being the greatest for a stretched cluster now.

On this with regards to the vCentre if you need independent recovery (and albeit easier) run a second vCenter. Also regarding creating additional VMkernal ports:
“As long as the customer does not touch the original deployed vmk adapters mgmt., vsan and vmotion adding additional VMk or port groups even with TCP/IP stack are not affected as generally they are ignored by our workflows…”

So it means replication is possible if both VxRail are under same vCenter or different.

What is the average bandwidth like for 2 Data domain average bandwidth is 6 Mb. and for replication between 2 VNX systems, bandwidth is 2 Mb.

It all depends on your backend network config really. So P2P, MPLS etc etc. But have a look at Duncan Eppings site yellowbricks.com and also https://pbradz.wordpress.com/tag/vxrail/
