bandwidth limit? can you be more specific......what replication technology are you using array replication? vSphere Replication?
what is the current link size and latency between the sites?
we do not publish limits as such for SRM. If using array replication then customers will usually work with the array vendor to outline their requirements i.e this is how much data we want to replicate, this is the data change rate, this is the type of replication we want sync/async will our current "pipe/link" handle it????
the array vendor can then work that out for you. bottom line if your requiremnts are more than your link can handle you have two choices fix the site-to-site connectivity issue using one of many possible techniques (bigger link, dedupe of replication data, compression...lots of options out there) or if the business won't invest in that stuff then you are left with "lowering your expectations" so if everyone said they wanted synchronous replication for example but there's no way your current link could cope or the change rate is too high you have to reset expectations.
for vSphere replication there is no limit published....again like array replication it will come down to number of vms you want to protect, unique write rate per-vm, desired RPO setting, once you have that you can use the figures in conjunction with latency on link, bandwidth size and workout what the average transfer size would be, how long it would take and whether it would fit inside the RPO window, you'll then have a good idea about what is/is not possible on the current link.
