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
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
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)
12
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)
13
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
14
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
15
Steps to increase efficiency

16
The importance of visualization
•systems & network
administrators have
tools for visualization
•useful for debugging,
benchmarking, capacity
planning, forensics
•data center managers
have comparatively poor
visualization tools
17
17
One form of visualization: CFD
Images: ANCIS
18
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

• 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


Top of rack
Middle of rack
eliminate leaks in floor
manage floor tile
permeability
21
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
22
Visualizing impact of maintenance
Under-Floor Pressure
• 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
Rack-Top Temperatures
• provisionally turn off one
or more CRAC units?
23
Feedback on floor-tile tuning
Before
• 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
24
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
Under-Floor Pressure
Rack-Top Temperatures
• without monitoring and
visualization, this
process is guesswork

how many tiles to remove?
25
Focus on a single sensor
• iterative process: too cold, too hot, just right
• monitor with laptop in data center for convenience
