Systems and methods for performing data input/output (I/O) operations using a computer network communications link are described. A method may include assigning a block of virtual addresses for usage with at least one computer network communications link. The method may also include registering the entire block of virtual addresses prior to an operating system partition performing I/O operations using the at least one computer network communications link, wherein registering comprises setting a plurality of virtual page frame numbers of the block of virtual addresses to point to distinct pages of physical memory. In some embodiments, one or more I/O operations may be performed using the at least one computer network communications link and the registered block of virtual addresses.
