New submitter linatux writes "HP has announced their 'Moonshot 1500 server' — up to 1,800 servers per 47U rack are supported. The tech certainly seems to be an advance on what is currently available — will it be enough to revive HP's server fleet?" From Phoronix: "Moonshot began with Calxeda-based ARM SoCs, but in the end HP settled for Intel Atom processors. Released today were HP's Moonshot system based on the Intel Atom S1200. Hewlett-Packard claims that their Moonshot System uses 89% less energy, 80% less space, 77% less cost, and 97% less complexity than traditional servers."
