This si kind of what we have... "Is the environment use windows DFS or anything? FRS was crap, but DFS-R (R2) might provide adherence to bandwidth limits on site-based replication. I'm looking at giving iscsi targets to windows off a local san (OF), and giving DFS-R a try to manage replications and such, just not sure how it stretches yet. Not positive, but worth a look if DFS is front-ending a windows server/client environment for your needs, supposedly it has wan-friendly qualities for such occasion. Doesn't solve all issues, but may in some cases." and it performs really well except when i do large data xfers from machine 1 and machine 2 with main data volumes as iSCSI on the same OF server. but that one is kind of expected. we are really having to go back to DFS/FRS i was just trying to explore options but for only2-3 more months of this its at this point just better to fix DFS again. however i still like OF as a filer.
