Our great and wonderful telco company has thrown a wrench into a new installation of 2 VNX5300 - our fiber won't be available until well after our target install date.  I do have an existing circuit to the DR site - is there anyway to use the existing IP infrastructure until our fiber is in place?  I have no iSCSI module on the SP - so are my choices to find a couple of those or put a FCIP device in place?
