The Octimod Mini-ITX Cluster
February 26, 2007
Ainkaboot's Octimod MPC7-1500 is a high density Gentoo Linux-based clustering platform based on Mini-ITX boards. Each processing module is hot-swappable, and contains a 1.5GHz C7 powered VIA EPIA EN 15000 motherboard.
Processing modules boot over the network from a server running on a module configured as a master node (or from multiple master nodes). SATA RAID modules provide shared storage, with a rack mounted distributed DC power supply providing power for each module. Up to 8 modules can be fitted in 4U 42 inch rack with - as the Octimod is only 300mm deep - an additional 8 modules mountable behind.
Cooling a server room is one the main costs associated with a datacentre. A C7 Mini-ITX board can consume 1W when idle and up to just 30W under load. A 4U Octimod rack of 7 CPU modules together with a drive module provides 10.5 GHz of CPU whilst consuming around 220W, or about 20 watts per gigahertz. Al Gore would be proud.
