Yes, it is possible. DART is installled on Control Volumes(luns) which reside on CLARiiON backend.
Did you installed Dart on Celerra ? or did EMC PS did it ?

Thanks

Does your new control station can ping the SP-A/SP-B. Is the control station management port (yellow long LAN cable) connected to the network switch to which CX is connected ?

Thanks

but when we are trying to install its not able to detect the backend . when i am entering SPA and SPB ip address and username / password its saying invalid
ip and username /password . So how to solve this issue

yes, if its two Celerra gateways (not if one is an NS Integrated)
naturually each would go into its own storagegroup

since DART needs to be installed by EMC or a qualified parter just ask support

They need to check firmware levels and update the databases anyway
