Title: PCIe write request acknowledgment

Abstract

A PCIe (Peripheral Component Interconnect Express) protocol converter for connection to a central processing unit (CPU) node having a root complex, a CPU memory fabric and CPU memory may include independent PCIe links, a fabric interface and a fabric switch connected to the fabric interface. Each of the links may include an endpoint for connection to the root complex. The fabric switch is connected to the fabric interface of each of the links and is connectable to a remote node. The fabric switch transmits writes of a single write request from the remote node across both links. Each fabric interface is to transmit an acknowledgment to the remote node in response to a write of the writes becoming observable at the CPU node hi Michael, hi Michael,.
