All, I have a 2801 and a 3800 routing WAN Traffic. At both ends, I have a SAN that we do replication with. My Question, I can I throttle the bandwidth or control how much bandwidth that the replication uses?

hi
AFAIK with SAN replication process around for seamless replication process you need high bandwidth between the locations to support the same.
do revert back on how much bandwidth you currently have between the sites and what kinda reservation plans you have in mind ..

You should be able to either. As long as you can identify the SAN traffic from your other traffic, you can police/shape it (which sets a bandwidth maximum), define a minimum bandwidth guarantee, do both, or prioritize it so that it only use excess bandwidth.

All, I have a 3mbps line. How would I limit the amount of bandwith the SAN would use, using a 2801 Router.
Thank you for your help.
