Despite every single link telling me an Equallogic 6100XV SAN cannot use 10gb modules, a vendor I contacted assures me it can. Does anyone know off hand?

Mine has the x11 module which is 4x 1gb. He sent me some screenshots of the SAN manager GUI that don't really have me convinced and used some pushy sales tactics. No need to push... if anyone can confirm this works I'll buy the thousand dollar X14 modules and be on my way. Thanks
