ARM Servers and Xen -- Hypervisor Support at Hyperscale
summary
Claim: ARM servers cut power and raise density for scale-out web, big data and storage workloads, with projections of ~40% microserver share in web‑2.0 stacks by 2016. Demonstrated kit: an EnergyCore SoC with integrated fabric, SATA/PCIe and BMC, shipped as a 10‑inch 4‑node card (4× SoC → ~16 GB memory per card) running Linux distros (Ubuntu 12.04 LTS, Fedora) and Xen (4.3/4.4) for virtualization. Measured figures: ~5 W per SoC, 10 Gb fabric with ~200 ns point‑to‑point latency; design targets work for large, low‑power clusters.
