Exploring The Green Blade Ken Lutz University of California, Berkeley LoCal Retreat, June 8, 2009
Motivation • To Realize An Energy Responsive Blade and Cluster • Consolidate Load within the cluster • Turn OFF Underutilized Blades • Explore a smaller unit of replication • Run on Battery providing Demand Response • Platform for System Level Experiments
Server Power Consumption Maybe we can explore a new data point
ATOM Blade • Explore a New Building Block • Inexpensive ($100) and Low Power (25W) • Based on the Intel ATOM 330 CPU • Dual Core – 45nm • 8W MAX • Smaller Unit of Replication so expect a cluster will have more units to do the same work • Fine Grain Control
Energy Responsive Node Node On/OFF Battery Backup AC ON/OFF ATOM UPS Controller
LoCal ATOM Cluster • (4) ATOM Motherboards – Almost 1U • 160MB Disk Drive • 10/100 Ethernet • 2GB DRAM • USB etc • DC-DC converter with UPS switch and Battery • Where is the power going?
Room for Improvement… ATOM CPU Bridge Chip Dc-DC Converter Clock Generator TV Encoder Audio Codec Intel I/O controller hub Chip
No Heat Sinks Not Steady State
Idle Power CPU Power Control Schemes may have a limited effect
Conclusion • The goal is to explore a new data point in cluster design • Small nodes allow fine grained load distribution • Ability to turn nodes off • Explore limited but distributed energy storage • Learn about the system level problems
