Hewlett-Packard (HP) had announced server cluster with the use of EnergyCore ARM RISC server chip. This hyperscale server is known as Project Moonshot. Redstone is going to be the first server platform under this project. HP states Project Moonshot as a extension to their previous ProLiant and Integrity server lines and not a replacement.
Moonshot is going to include superdense servers based on Intel low power Xeon and Atom chips and Advanced Micro Devices low-power x86 processors as well as multiple ARM-based server chips.
Redstone is going to use Calxeda chips. Right now Redstone has 32 bit chips and HP says many customers think it’s fine. These chips can be targeted for web serving, web caching and data chewing workloads.
The half rack of Redstone machines will be providing 1600 server nodes and will have 41 cables using 9.9 kwatts for $1.2m compared to traditional x86 based cluster with 10 rack space, 1600 cables using 91 kwatt for $3.3m. These numbers are impressive but the big caveat is, it will work for the workloads that can scale well on a modestly clocked (1.1GHz or 1.4GHz), four-core server chip which works only with 32-bits and has 4GB of memory.
