HI all'

today im using a A/A san with vplex/xio/vc6u2 over wancom

works great.

but thats for the SAN part .nas???

after some investigation i was pointed to the new feather for the   synchronous replication with witness.

at this is a new NAS implementation im ok with the the basic requirements  by EMC.

now the question is if there anyone how tryed this feather and can report success of failure?

and what shuold i take in consideration when going to this move?

im gone sync replicate two vnx5400 nas over ip between two sites (20GIGABIT DWDM lines with sum mili RT)

what  is the penalty for going to this action?

regards,
