Does Intel® Virtual RAID on CPU (Intel® VROC) Support Dual-Port Drives?

Description

We are using two CPUs to connect a U.2 NVMe disk that supports dual port. In this case, Server A and Server B are connected to the same U.2 NVMe disk. Intel VROC RAID function is enabled on one of these servers. Can this dual-port disk work normally in the RAID state?

Resolution

Intel® VROC does not support dual-port drives.

The only way to use a dual-port drive with Intel® VROC is by disabling first the dual-port (multipath) feature and not using it. That of course, will defeat the whole purpose of having the dual-port drive.
