Towards a Greener Data Center: Tools & Techniques

Motivation

• Energy efficiency = core DOE mission several LBNL researchers study power consumption

of IT equipment (data centers, servers, power supplies, cooling, UPS technology)

• More pragmatically: data center resources are increasingly scarce! power, space, cooling all in short supply

• Why? Significant growth in cluster computing: 40% of LBNL scientific teams need or use clusters 70% interested in cycles on shared cluster

10

Page 11: Synapsense Powerpoint Presentation (10mb)

11

Motivation: scientific computing

• Demand for computing cycles is growing rapidly on many campuses, not just LBNL

the direct expression of a broad scientific need

• IT’s primary data center runs out of capacity between 2010 and 2012 depending on cluster growth rate (7% - 20%)

• Strategically, we must maximize efficiency of current data center even as we locate new space

11

Page 12: Synapsense Powerpoint Presentation (10mb)

12

The story of a data center: 50B-1275

• Several decades old ~5000 sq ft 18” raised floors ~.5MW total power consumption

• Combination of clusters and business systems clusters account for almost all new demand

• Unusual cooling system 7 down-shot CRACs for under-floor supply supplementary overhead supply (chiller coil + fans)

Page 13: Synapsense Powerpoint Presentation (10mb)

13

The story of a data center: 50B-1275

• Starting summer of 2007, IT began a data center efficiency effort

• In collaboration with researchers in EETD, we perform a series of engineering studies documenting electrical, mechanical systems measuring loads & capacities; performing CFD calculating efficiency identifying opportunities for improvement deploying wireless sensor system (more later)

Page 14: Synapsense Powerpoint Presentation (10mb)

14

What we learned

• The data center was overcooled but this is the norm

• Abundant low-hanging fruit simultaneous humidification & dehumidification blanking panels missing excessive number of perforated floor tiles air-flow pathologies (mixing, short-circuiting)

• The data center was relatively efficient! none of the clusters backed by UPS

Page 15: Synapsense Powerpoint Presentation (10mb)

15

Taking steps to increase efficiency

• Improved airflow overhead plenum converted to hot-air return supplementary cooling directed under floor floor-tile tuning blanking panels, curtains, etc

• Virtualization• Water cooling• Wireless environmental monitoring system

The importance of visualization

17

•systems & network administrators have tools for visualization

•useful for debugging, benchmarking, capacity planning, forensics

•data center managers have comparatively poor visualization tools

Visualization and real-time monitoring

• We installed a wireless sensor net from SynapSense 200 monitoring points temperature, humidity, under-floor pressure, current

• For the first time, we have a detailed understanding of environmental conditions in the data center real-time and historical graphs underlying database

• SynapSense is a technology transfer success story from UC Davis CTO and co-founder is Raju Pandey, also Computer Science professor at UCD http://www.synapsense.com “You can’t control or manage what you don’t measure.”

SynapSense hardware

• wireless sensor network• “self-organizing” nodes• 802.15.4 (not 802.11)• multi-hop routing• non-invasive installation• 2 internal & 6 external

sensors per node• we measure temp.,

humidity, pressure, current

• we could measure liquid flow, liquid presence, particle count

Learning from the sensors

• lesson #1: eat your spinach!

• effect of adding one 12” blanking panel to the middle of a rack

• conventional wisdom is correct: blanking panes are essential

• other data center clichés also borne out eliminate leaks in floor manage floor tile

permeability

Visualizing impact of site modifications

• Graphing impact of major maintenance (redirection of overhead cold air supply underfloor) on air pressure in some areas, under-floor pressure increased by almost 50% impact varies according to distance from new air supply

Page 23: Synapsense Powerpoint Presentation (10mb)

23

Visualizing impact of maintenance

• each CRAC turned off in turn, for service

• hot spots monitored during maintenance

• two-fold benefit real-time feedback enhanced knowledge of

data center redundancy characteristics

• provisionally turn off one or more CRAC units?

Feedback on floor-tile tuning

• in the course of one day 24 perforated floor tiles

removed 6 floor tiles converted

from high- to low-flow 4 floor tiles converted

from low- to high-flow

After

Page 25: Synapsense Powerpoint Presentation (10mb)

25

Feedback on floor-tile tuning

• with instrumentation, we can observe results in real time

• when airflow is restricted, under-floor pressure

increases rack-top temperatures

decrease

• without monitoring and visualization, this process is guesswork how many tiles to remove?

• iterative process: too cold, too hot, just right• monitor with laptop in data center for convenience
