Persistent Remote Direct Memory Access

摘要

In an example, there is disclosed a computing apparatus, including: a host fabric interface (HFI) for communicatively coupling to a fabric controller of a fabric; an asynchronous data refresh (ADR) having an auxiliary power and an ADR buffer; and a memory controller including logic to: directly access a persistent fast memory of a remote computing device via the fabric; detect a primary power failure event; and flush data from the ADR buffer to the fabric controller.
