The Stratos S900-X31A is the second major server to be announced based on the 64-bit Centerton chip. In June, HP as part of its Gemini server platform that will use Centerton, in addition to processors based on other architectures.
Low-power servers are drawing interest as an energy-efficient way to handle certain large-scale workloads, such as big data applications and Web transactions. Atom processors are usually found in low-power laptops and tablets, and companies have also been experimenting with servers based on ARM processors, which are found in most tablets and smartphones. Advanced Micro Devices is offering a SeaMicro server with Atom processors, and HP and Dell are offering ARM-based servers for testing purposes.
Quanta's microserver will have 24 or 48 nodes in a 3U chassis. It will consume less than 10 watts per node and offer better performance-per-watt than traditional 1U single-socket servers, according to Quanta.
Some industry observers believe a collection of lower-power "wimpy" cores, such as Atom or ARM, offer better performance-per-watt for some online workloads than "brawny" cores, such as Intel's Xeon or AMD's Opteron.
Intel's Centerton processor draws 6 watts of power, and the company next year plans to launch a new Atom server chip code-named Avoton, which will be made using the 22-nanometer process.
