Abstract: A non-volatile memory express over fabrics (NVMeoF) redundant array of independent disks (RAID) controller includes an NVMeoF RAID target module, an NVMeoF RAID implementation module, and an NVMeoF RAID initiator module. The NVMeoF RAID target module receives one or more NVMeoF commands from one or more computer hosts. The NVMeoF RAID implementation module receives the one or more NVMeoF commands from the NVMeoF RAID target module and performs RAID functionalities on the one or more NVMeoF commands. The NVMeoF RAID initiator module receives the one or more NVMeoF commands from the NVMeoF RAID implementation module and transmits the one or more NVMeoF commands to the one or more storage target devices to establish one or more virtual queue pair connections and enable direct data transfer between the one or more computer hosts and the one or more storage target devices.

Abstract: A method of accessing a Non-Volatile Memory express over Fabrics (NVMeoF) memory region of a remote target device includes establishing a NVMeoF transport connection with the remote target device and creating an admin queue by sending a NVMeoF connect command to the remote target device. The method includes accessing the NVMeoF memory region of the remote target device by sending PropertyGet/PropertySet commands to an admin submission queue of the remote target device, performing one of (a) receiving PropertyGet/PropertySet completion queue entries from the remote target device when accessing the NVMeoF memory region of the remote target device is completed, or (b) receiving at least one of RDMA write and RDMA read requests from the remote target device in response to PropertyGet/PropertySet submission queue entries, and receiving completion queue entries from the remote target device when the accessing of the NVMeoF memory region of the remote target device is completed.
