Disaster Recovery / Data Replication:
i) Ask about the connectivity of Primary & DR Site. Is this connection is capable to transmit data with proper BW?
ii) How DR is happened? Software based (Veritas Volume Replicator/Oracle DataGard) or Hardware based replication (Storage based – 6140/6540/6920/up++) which is D2D (disk to disk replication)
iii) If HW based replication then find out that selected storage has FCiP facility.Otherwise, you need to add McData FCIP router before use Normal SAN FC Router.

Connectivity:
