1 HETEROGENEOUS SENSOR NETWORK FOR DATACENTER WORKLOAD AND POWER MANAGEMENT JORGE ORTIZ CS294-14 ARCHITECTURES FOR INTERNET DATACENTERS OCTOBER 10, 2007 Sensing the Datacenter

2 Datacenters Consume Lots of Power Datacenter power consumption increasing  Environmental Protection Agency (EPA) report shows power- consumption has doubled in last 5 years  1.5% of total U.S. Electricity Consumption in 2006  Projected to double again in next 5 years Datacenter under-provisioned for saving power  Sensing and control separate from load balancer  Protocols and applications are energy unaware What I propose:  Couple the sensing and control with the load balancer/tasking decisions  Dynamic Adjustment  Graceful workload adjustment for saving power

3 Sensors Facilitate Dynamic Energy Accounting Include power-related input into the protocol and management loop Make use of equipment sensors already available to gather information about power consumption  Power meters to attach to server/racks  On-board temperature sensors  In-band network monitors Wireless sensor network technology to include out-of- band monitoring infrastructures  Single on-board sensors sometimes give wacky readings  Array of sensors adds redundancy and improves accuracy  Wireless motes ease deployment and data collection

4 Loose Ends Datacenter-scale workloads unavailable  Monitoring machine room activity not at same scale as internet datacenter, but it’s a good start Power metering equipment needed  A couple of one-outlet monitors already in use Access to 420A (Soda Hall Machine room) or the RadLab Machine room Direct access to specific machines in (either) machine room

5 Semester Plan Provision the Soda Hall machine room (420A) or the RadLab machine room with wireless sensors (temperature, humidity, etc.) Attach power meters to a set of servers in the machine room Setup process (top), network (netstat), and disk monitors (iostat) to determine distribution of machine activity Analyze gathered data  Formulate a model that relates temperature and power consumption  Analyze the relationship between component utilization and ambient temperature  Machine-learning techniques for formulation of predictive models for graceful workload degradation
