Most all V-Series implementations use local Active-Active V-Series controllers and are fabric attach to local third party arrays. V-Series also supports MetroCluster using fabric and long distance ISL to attach to storage.
Sounds like you need a solution where the V-Series controllers are at one location and the array would use distance ISLs to attach to some remote storage. While this should work, it’s far outside the typical configuration we test for and this is an unusual configuration. There are many ways to get the implementation wrong and would advise against going outside what we typically support.
If you need this solution, you should fill out a PVR and the detailed V-Series support document with the proposed configuration for review. We would need to know the distance mechanisms, hops, all switch firmware, long distance transport, array info, etc.
