Extremely Low Power, High Density 3U Microserver

With 24 server nodes in a compact 3U chassis, the Quanta STRATOS S900-X31A is the most advanced microserver built upon Intel® Atom™ processor S1200 product family which supports 64-bit computing architecture and ECC memory for the enterprise. S900-X31A delivers dramatic power efficiency: less than 10 watts per node, with industry-leading thermal and space design. It is optimized for the applications of dedicated web hosting and hyper-scale workloads.

High Density and Simplicity

The S900-X31A is designed with one goal: Simplify datacenter operation by increasing density and reducing cabling complexity. One Quanta S900-X31A microserver contains 12 cable-free, hot-pluggable sleds that are independently operative. Each sled has 2 server nodes powered by Intel® Atom™ processor S1200 product family for microservers. Each node supports up to 8 GB of memory, two 2.5" internal HDDs, and one GbE RJ45 port.


All server nodes can share one console port and two 10GbE SFP+ ports for uplink via an optional switch board. Comparing with competing solutions offering isolated management design, Quanta's microserver requires users to attach only one network cable on a dedicated management port to manage all nodes. QCT's innovative internal Ethernet switching board and integrated management design not only greatly simplify the cable management and make the remote management much easier for datacenters, but also reduce the OPEX & CAPEX by eliminating extra Top-of-Rack switch and network cable equipment need.

Everything Goes Efficient

S900-X31A shares components including fans, power supplies, and Ethernet switch in a Quanta X3 3U chassis. Plus support of extremely low power processors, the STRATOS S900-X31A dramatically lowers power consumption and increases heat dissipation. The shared infrastructure design makes S900-X31A especially attractive for datacenters with limited power and space. Therefore, the microserver not only largely cuts cost, but also dramatically saves energy, datacenter floor space, and cabling to achieve greater performance/watt and performance/dollar compared to traditional 1U 1-socket servers.
