Rick,

dave graham from EMC here. I can help you get the information you need.

I'll need the array type (Clariion CX3, CX4?), connectivity protocol (FC, iSCSI) as well as the current WAN link between sites.

as Mrdenny says below, the change rate over 30 minutes would be helpful. We can also collect NaviAnalyzer data (NAR or NAZ files) and process those through a tool here.

cheers,

Dave
