Abstract:
1. A method of enhancing write performance in a network including first and second switch devices coupled over a high latency network link, wherein the first switch device is coupled to an initiator device over a first high speed network link, and wherein the second switch device is coupled to a target device over a second high speed network link, the method comprising: responding to a write request received by the first switch device from the initiator device with a first ready-to-transfer (RTT) message on behalf of the target device, the first RTT message requesting write data from the initiator device; receiving the write data from the initiator device at the first switch device, the write data being sent in response to the first RTT message; and sending the write data from the first switch device to the second switch device over the high latency network link, responsive to receipt of the write data from the initiator device and independent of receipt of a RTT message from the target device by the first switch device.
