An I/O communication adapter receives from a processor core an I/O command referencing an effective address within an effective address space of the processor core that identifies a storage location. In response to receipt of the I/O command, the I/O communication adapter translates the effective address into a real address by reference to a translation data structure. The I/O communication adapter then accesses the storage location utilizing the real address to perform an I/O data transfer specified by the I/O command.
