Yesterday HP announced retail availability of two ARM based servers, the ProLiant m400 and m800. Each are offered in a server cartridge as part of the Moonshot System. A single 4.3U Moonshot chassis can hold 45 server cartridges. Usually higher numbers mean better, but in this case the m400 and m800 are so significantly different I wouldn’t consider them competitors. The m800 is focused on parallel compute and DSP, while the m400 is focused on compute, memory bandwidth, IO bandwidth and features the first 64-bit ARM processor to reach retail server availability.
