Would it be possible to implement qos on srdf/s traffic? Presently we have 4 dedicated LES100 links which we use to replicate the srdf/s traffic from one site to another. I've been asked if the srdf traffic could moved over to our LES1000 link which we use to route all other traffic from site to site. We use 3750 switches to terminate the LES100 links and to connect to the EMC equipment. There is just one vlan on which spans across the LES100 links for the srdf/s traffic.I have no experience of the SAN but would imagine the srdf/s traffic would need an LLQ.
