The USB Implementers Forum has adopted NVIDIA's ESA technology:
As a result, the ESA protocol, which details the way PC peripherals can communicate with each other, will now be added into the next revision of the USB human interface device (HID)-class definition.
Furthering ESA momentum within the industry is the global availability of ESA-certified PC components produced by many of ESA’s founding partners, including Cooler Master, CoolIT Systems, NVIDIA®, PC Power & Cooling, Silverstone, Tagan, and Thermaltake. In addition, the new Dell XPS 630 is the first commercially-available desktop PC to be ESA-certified. The XPS 630 incorporates Dell’s innovative LightFX technology, which utilizes the ESA real-time communications protocol to provide developers an easy way to create highly immersive gaming experiences by synchronizing on-screen gaming action with the ambient lighting integrated into the PC chassis.
Originally introduced in late 2007, ESA was designed and introduced to support new monitoring and control capabilities for PC devices such as chassis, power supplies, and water and air cooling peripherals. Until the introduction of ESA, there was no standard communication protocol allowing such components to report information back to users. Essential data, such as temperature, thermal, voltage, and air flow attributes are made available in real-time and are critical to obtaining maximum PC performance and overclocking. With ESA, component manufacturers can now embed a wide variety of digital and analog sensors into their devices which can communicate real-time data for use in analyzing and optimizing overall PC operating conditions. In addition, ESA’s logging functionality offers PC manufacturers and system builders an inexpensive and easy way to help identify PC operating abnormalities, and enable them to quickly identify and resolve customer support issues.
