Abstract: Systems and methods which allow for one or more input/output (I/O) ports residing on a device in a storage network environment to be reconfigured in order to communicate using different protocols are provided. Embodiments may provide for dynamic reconfiguration of an I/O port while the device including the port is deployed in the storage network. In some instances, such reconfiguration may be managed locally and/or by a remote management processing resource in the storage network. In some embodiments, reconfiguration of an I/O port to communicate in a different protocol may be implemented, either manually or automatically, based on observed traffic data.

Abstract: A novel RDMA connection failover technique that minimizes disruption to upper subsystem modules (executed on a computer node), which create requests for data transfer. A new failover virtual layer performs failover of an RDMA connection in error so that the upper subsystem that created a request does not have knowledge of an error (which is recoverable in software and hardware), or of a failure on the RDMA connection due to the error. Since the upper subsystem does not have knowledge of a failure on the RDMA connection or of a performed failover of the RDMA connection, the upper subsystem continues providing requests to the failover virtual layer without interruption, thereby minimizing downtime of the data transfer activity.
