Abstract
A method in a system that includes first and second devices that communicate with one another over a fabric that operates in accordance with a fabric address space, and in which the second device accesses a local memory via a local connection and not over the fabric, includes sending from the first device to a translation agent (TA) a translation request that specifies an untranslated address in an address space according to which the first device operates, for directly accessing the local memory of the second device. A translation response that specifies a respective translated address in the fabric address space, which the first device is to use instead of the untranslated address is received by the first device. The local memory of the second device is directly accessed by the first device over the fabric by converting the untranslated address to the translated address.
