BfSS will not work. we see vPLEX volume and can not bring this together with the snapshot on the storage.
As the volume is 1:1 forwarded by vPlex you maybe have luck with VESS. This will be unsupported somehow.... and you have to zone the vnx to the esxi hosts as well. I would then create a very small (40MB) helper volume that you can map from VNX to esxi host for testing the connectivity.
