Patent Searching and Data


Title:
COMPUTER SYSTEM AND METHOD FOR COMMUNICATING DATA BETWEEN COMPUTERS
Document Type and Number:
WIPO Patent Application WO/2013/136522
Kind Code:
A1
Abstract:
The objective of the invention is to achieve communications between servers by use of PCle switches without using any conventionally used network devices of Ethernet. In a computer on the transmission side, an NW driver, which is recognized, by the OS, as an NIC driver, stores data to be transmitted and a destination SPA into a memory, and outputs a transaction layer packet (TLP), which has been generated by a first computer, to a PCle switch. A first NIC logic of the PCle switch corresponding to the first computer on the transmission side adds a system port address (SPA) to the TLP transferred from the first computer, and transfers the data of the TLP to a port associated with a second NIC logic and having an address indicated by the SPA (destination SPA). The second NIC logic having received the data writes the received data into a memory of a second computer, on the reception side, which is connected to another PCle switch where the second NIC logic exists.
