UNSOLVED
Hello Christopher thanks by your reply let me clarify the question, I have one VNX-5200 Unified and I looking to use both Datamover (server_2 and server_3) active/active for NFS and CIFS client access and not use active/standby, there are some recomendation for this cenario? What is the EMC recomendation active/active or active/standby? And when one Datamover fail in active/active the clients CIFS and NFS need just reconnect or I need manual intervention?
Tks.

EMC recommendation is to use active/passive unless you are willing to accept the risk of data unavailable situation in case one of the datamovers fails. If both are active/active, when one datamover fails, its resources (CIFS/NFS, files system) will NOT be available on the other datamover.

Correct,
An Active Datamover cannot be used as a failover for another active datamover. So if you go active/active, there will be no failover functionality available.
What is the problem you are trying to solve by going to Active/Active?

If I understand your question correctly, you are asking if any block (FLARE) luns presented to the data movers use the Symmetric Active/Active (as a reminder, must be FLARE LUNs without any advanced data services enabled).
No, the data movers (at least currently) do not support Symmetric Active/Active and will therefore use Asymmetric Active/Active (ALUA).
