Interesting tidbit regarding I2O from ANCR post 23181: NGIO changes the method that the CPU uses to transfer data. Instead of the directly synchronized transfers between the peripheral and a CPU, NGIO uses messages to create packets of data that can be sent between each Target Channel Adapter and the Host Channel Adapter. Even I2O, which offloads I/O processing from the CPU to the I/O controller, still uses synchronous communications, which is clearly a limiting factor. NGIO's asynchronous communication frees the CPU from having to wait for data from the slower peripherals. With multiprocessor systems, this becomes even more important, as processors tend to compete for the slower peripheral bus. **** We have been been told that I2O is still coming, and that I2O will be incorporated in the new I/O standards. But judging by the poor I2O revenues to Wind, and the paucity of news, and the Wind stock price, I have my doubts. This snippet indicates that NGIO and Future I/O may pass by I2O. I am long Wind, and believe the future is bright, but I am prepared to write off any significant contribution from I2O. Are there any technology buffs familiar with NGIO and Future I/O who can enlighten me? wj
