ARM vs x86 Servers Benchmark – Calxeda EnergyCore ECX-1000 vs Intel Xeon E3-1240

Calxeda has released the results of ApacheBench benchmark comparing their ARM-based EnergyCore solution to an Intel Xeon server in order to showcase the performance and the much lower power consumption of their servers. Here’s the setup: Hardware: Single Calxeda EnergyCore ECX-1000 @ 1.1 GHz, 4 GB of DDR3L-1066 memory, 1Gb Ethernet network port and 250 GB SATA 7200rpm HDD Intel Xeon E3-1240 @ 3.3 GHz, 16 GB memory and 1Gb Ethernet network port. No info on hard drive provided Software: Ubuntu Server v12.04 Apache Server v2.4.2 ApacheBench v2.3 (16k request size) They performed power measurements every 2 seconds and averaged the results. Power supply overhead and hard drive power consumption were not excluded in the measurement, but the entire SoC and DDR memory power consumption were included together. For the Intel server however, they could not measure directly, so they used published TDP values for the CPU (80 W) and I/O […]

This is What a Calxeda 192-Core ARM Ubuntu 12.04 Server Looks Like

Last November, Calxeda announced its 32-bit ARM Chip for servers, and now there are been some good progress as Calxeda is currently showcasing a 192-core ARM Server running Ubuntu 12.04 LTS Server edition at the Ubuntu Developer Summit in Oakland, California. The server showcased has 192 cores (48 Calxeda EnergyCore quad core Cortex-A9 processors), consumes less than 300 Watts, supports up to 24 SATA drivers and runs Ubuntu 12.04 with OpenStack’s cloud management infrastructure. Karl Freund, Calxeda Vice President of Marketing said that the Calxeda server is running “a standard LAMP stack (running Calxeda’s website) along with other popular web frameworks such as node.js and Ruby on Rails, provisioning of OpenStack Nova compute instances, and even Canonical’s Metal-as-a-Service bare-metal provisioning.” The company also explained that a complete native build of the Ubuntu 12.04 kernel took less than an hour to build on a single node, 4 times faster than the […]

The Past, Present and Future of Ubuntu for ARM

David Mandala of Canonical talked at Linux.Conf.Au on 18th of January 2012 about Ubuntu for ARM and the move from netbook to server support. You can read my notes below, or jump at the end of this post to watch the presentation. The Past 2008: Ubuntu decides to only support ARMv7 architecture vs. Debian that supports ARMv4 and above. 2009: Ubuntu release for Freescale i.MX51 (ARMv5 built), and then Marvell ARMAVA with ARMv6 and VFP (ARM floating point unit) support. 2010: April (10.04) The first ARMv7 release for OMAP3 (Beagleboard) with VFP, Thunb2, NEON and SMP for ARM and first netbook edition October (10.10) Pandabord (OMAP4) release with initial device tree support for ARM. Starts work with Linaro. 2011: 11.04 (5th release) – Supports OMAP3 and OMAP4 only. The netbook edition is using Qt, further improvement to device tree, further work with linaro and on the way to the Unified […]
