Does Replication Manager have WAN capabilities similar to Replistor?

Hello all.  We are currently running Replistor on our SQL, Exchange, and File servers on a small VMWare cluster.  They are currently being replicated to a remote site via WAN.

I found out EMC will no longer be supporting Replistor and Replication Manager will be taking its place.

I was wondering, does Replication Manager push block level I/O changes via WAN, similar to Replistor?

I tried to look through the documents but I couldnt find anything on setting up a cache directory so incase the WAN link goes down, the changes to the filesystem are being queued up.

I dont have an EMC partner, so I am on my own with the research.

Thanks all!
