Multiple translation control entries (TCEs) at the same indices in multiple, same size TCE tables are mapped to facilitate data communication between a self-virtualizing input/output (IO) resource and a logical partition. First and second TCE tables used by an adjunct partition that interfaces a self-virtualizing IO resource with a logical partition may be identically sized, so that whenever a direct memory access (DMA) operation between the self-virtualizing IO resource and the logical partition is desired the same TCE entries in the first and second TCE tables may be used to perform a redirected DMA operation, and without the need to perform hashing or other mapping algorithms to map to the respective TCE entries in the respective TCE tables.
