How to Maximize Data Center Efficiencies with Rack Level Power Distribution and Monitoring Brian Rehnke e-pdu Business Development Manager November, 2011
The Problems Energy Usage in most data centers has grown 2 3x in last 3 years Lifetime (3 yr.) Energy costs to support a server will soon exceed its acquisition costs Energy costs will continue to increase Through 2009, energy costs emerged as the secondhighest operating cost (behind labor) in 70% of DC facilities worldwide* Increasing Corporate responsibility to reduce greenhouse gas emissions and be more efficient * Source: Gartner; Meeting the DC power and cooling challenge 2 2
The economic times With the increased pressure for companies to control or reduce costs, you may ask yourself; Where do I begin? 3 3
Start with Enclosure Power Distribution Units Outlet level monitoring and control Outlet level power measurement helps you make intelligent decisions to reduce power consumption Outlet level granularity allows decisions to made based on what individual servers are doing This information gives you total control over power usage and trends 4 4
Market Drivers Drivers According to IMS, outlet level monitoring is the fastest growing PDU technology Expected increasing focus on data center efficiency requiring measurement end-to-end High level of focus on allocating power usage based on customer or department 5 5
epdu Marketplace How large is the current marketplace for epdu like products in North America?? Answer $700M+!!!! Projection for 2017?? Over $1 Billion!! *All figures from IMS Research 6 6
Where Are epdus Used 7 7
Power Usage Effectiveness PUE is a metric used to determine energy efficiency in a data center Power entering facility/power used to run equipment Need units to provide outlet level power consumption for Level 3 PUE calculations Level 1: basic, uses UPS readings Level 2: Intermediate, uses PDU level readings Level 3: Advanced, uses server/outlet level reading 8 8
2 levels of rack epdu that can support PUE Advanced Monitored High accuracy outlet level monitoring Local or remote current, voltage, power No outlet switching to address security concerns Designed for 24/7 manned facilities Additional Options to look for to maximize effectiveness of epdu Current, voltage, power monitoring (KWH) Environmental monitoring, temperature, humidity and contact closure (EMP001 required) Internal temperature probe on monitoring circuit board to track ambient temperature Outlet LED on/off and blinking alarm Advanced LCD pixel display to provide current, voltage, power and configuration 9 9
2 levels of rack epdu that can support PUE Managed Outlet level monitoring + switching Local or remote current, voltage, power Outlet switching for lights out management (on/off/reboot) Additional Options to look for to maximize effectiveness of epdu Advanced display Backlit LCD pixel display allows variable text, number, images Dual color allows local indication of alerts Invert display for overhead power Local display of current, voltage, power View IP critical parameters using button menu 10 10
Future Proof Your Net Management Card Look for support of both IP 4 and IP 6 for future expansion IP addresses are all assigned Don t spend money to update again in just a few short months or years! Secure web server interface SNMP V1 and V3 for security (https://) Get e-mail alerts Universal integration to 3 rd party software using SNMP MIB Disable Telnet or HTTP for security if not being used Option for read only access for users to prevent outlet shut down or configuration changes 11 11
Improve IT Asset Utilization for Efficiency Retire unused software applications Effective software (eliminate extra CPU cycles, i.e. bloatware ) Consolidation (blade servers, software, etc.) Turn-off idle IT equipment* Test and measurement of servers to determine most efficient running times and efficiency at running various programs* Datacenter management software* Operate at higher, more efficient voltage levels* 230V/400V three phase power 12 12
Input Voltage Advantage Virtually all IT equipment is rated to work from 100V to 240V AC input 2% Efficiency gain by using 208V instead of 120V 3% Efficiency gain by using 230V instead of 120V 13 13
Amps Volts KW KWH WTH?? Amps tell you how close you are tripping a circuit breaker Volts tell you how close you are to lights dimming KW (Kilowatt) tells you how much power something consumes example 60 watt light bulb versus florescent drawing 20 watts draws 1/3 as much power KWH (Kilowatt Hours) tells you how much power was consumed over a period of time think of your electric bill subtract June 30 th reading from May 31 st reading and you get total June power consumption 14 14
Amps Volts KW KWH Data Center Amps tells you how much circuit capacity you have left in your rack, find capacity, find $$$ Volts tells you if server power supplies are running at a reliable level, higher voltage lower current and typically better efficiency $$$ KW (Kilowatt) tells you which server is more efficient and which one will save you $$$ KWH (Kilowatt Hours) tells you how much power your consuming reduce it and you save $$$ 15 15
Time Stamping Configure date and time for KW hour date stamping Automatically configure a time server for NTP synchronization 16 16
Don t Forget Installation Costs! Save time and money by having faster, easier installation Flexible mounting options including support for tool-less industry keyhole mounting Flexible clip foot snap in installation Color coded circuit breakers and numbered outlet identification simplifies setup instructions for installation personnel Aluminum chassis is lightweight and dissipates heat better than steel 50 C temperature operation 17 17
