HP will use Intel Atom for first low power 'Moonshot' servers, but what about ARM?
Late in 2011, Hewlett Packard announced "Project Moonshot," an initiative to shrink data center size and energy consumption by using "hyperscale" low-power servers.
Initially, HP announced the project's low-power server design codenamed "Redstone" was based on Calxeda's ARM-based EnergyCore processors which used just 1.5 Watts of power per SoC. At the same time, ARM announced it was getting into the server business with its first ever 64-bit architecture. The excitement for ARM servers was high.
