What Is Direct Cache Access - Web direct cache access (dca) i/o device dmas packets to main memory. Web direct cache access (dca) enables a network interface card (nic) to load and store data directly on the processor cache, as conventional direct memory access (dma) is no longer suitable as the bridge between nic and cpu in the era of 100 gigabit ethernet. Rdca allows the rnic to enjoy the high bandwidth of cache. Cpu later fetches them from cache. However, in traditional architectures, memory latency alone can limit processors from matching 10 gb inbound network i/o traffic. Pcie transaction protocol processing hint (tph) i/o device. Web we coin the name remote direct cache access (rdca) for this design. Requires os intervention and support from processor. Dca exploits tph* to prefetch a portion of packets into cache. Still inefficient in terms of memory bandwidth usage.
