I2O technology

I2O, which stands for Intelligent Input/Output, addresses one of the weakest links in turning today’s PCs into servers: degraded CPU performance due to heavy I/O processing. By offloading much of the I/O workload to the SuperTrak66 controller card processor, the I2O architecture frees the system CPU from the many low-level requests involved in RAID operations.

I2O is a forward-thinking approach to resolving the long-standing issue of platform interface independence. Since I2O drivers are supplied by the maker of each operating system, I2O product manufacturers can focus on product development rather than thinking about building specific drivers for each individual operating system. Theoretically, any product that is I2O compatible becomes cross-platform- compatible with all operating systems that support I2O.

At the time of this writing, only Windows NT 4.0 is officially supported by SuperTrak.
