So the rumour proved to be true, Calxeda will indeed be the chip partner that will allow HP to bring the first ARM-based servers to the market.
HP now has the Redstone Server Development Platform which will be used by the company internally for "testing, developing and benchmarking hyperscale applications".
Calxeda's CEO Barry Evans, said in a statement that, a single 4-rack unit chassis designed by HP can contain a staggering 288 Calxeda servers and would deliver the same throughput as 700 traditional servers.
In addition, the infrastructure needed to sustain the servers and manage them will be dramatically simplified with less cabling, an integrated management solution and less hardware.
Calxeda didn't go for raw power and chose instead to focus on performance per watt and total cost of ownership, with Calxeda expecting to capture more than five per cent of the global server processor market over the next five years.
As part of its Moonshot programme, HP may use EnergyCore chips in microservers. The company has introduced a popular microserver, the Proliant N36L, which is based on the AMD Athlon II CPU.
