Bosch VMS did not support multipathing and controller redundancy with Dell storage platforms at the time of our testing.
The Bosch Video Recording Manager load balances the write throughput across all available storage. A NIC failure causes a target and the associated LUNs to be unavailable. No data loss is observed in case of a failed storage target, however the data on those LUNs is inaccessible until the network connectivity is restored.
