DESCRIPTION
Power Strategies for Data Center Efficiency – Identifying Cost Reduction Opportunities In a survey conducted by the Uptime Institute, enterprise data center managers responded that 42% of them expected to run out of power capacity within 12-24 months and another 23% claimed that they would run out of power capacity in 24-60 months. Greater attention to energy efficiency and consumption is critical. To view the recorded webinar presentation, please visit http://www.42u.com/power-strategies-webinar.htm

Basic Power

Advantages Disadvantages
Standardization on a single manufacturer's products, footprint, MTBF expectations, etc.
No additional tools to manage power related issues either locally or remotely
Minimal investment in providing reliable power distribution within the equipment rack
Retrofitting existing environments can be more expensive than perceived benefits
Certain options do include branch-circuit protection to isolate power issues and maintain as much operational equipment as possible
Relatively inexpensive power infrastructure improvement for any size datacenter
Metered Power
42U Confidential ©2008 42U All rights reserved Slide 19
Advantages Disadvantages
Provide visual indicator of amperage draw per circuit within the physical data center environment
While visual indicators are valuable at locations with local IT personnel, these cues don’t provide information to remote resources and IT personnel
Eliminate circuit overload by accurately measuring consumption and allowing IT professionals to maintain optimal 80% power loads
Since there is no ongoing logging availability, trading cannot be utilized for resource planning when adding or changing equipment configurations
Monitored Power
42U Confidential ©2008 42U All rights reserved Slide 20
Advantages Disadvantages
Provide true real-time power status for monitoring purposes and addressing issues as they occur
Information provided can be of significant value, but does not provide the ability to mitigate problems and reduce MTTR from off-site locations
Information can be sent to single or multiple off-site locations for interpretation and selection of appropriate response planning
Important alert information still necessitates involving other support aspects, including non-skilled personnel, third party technicians, or costly truck rolls
As information is being exported from the individual hardware devices, real-time and historical information can be catalogued and stored, and analyzed for troubleshooting and resources planning purposes
Switched Power
42U Confidential ©2008 42U All rights reserved Slide 21
Advantages Disadvantages
Provide out-level control for attached IT resources and ability to hard-boot systems that have failed in the field
Security; once the hardware provide the ability to manage device level power, security processed must be implemented and monitored to ensure procedures cannot be circumvented
Most solutions allow association of multiple power supply devices between multiple circuits to provide consistent power cycling when the need arises
Investments can be more significant that traditional PDU’s – it is important to generate a true ROI for the purchases versus 3rd party technical support, potential issues with non-skilled personnel, truck roll expenses, etc.
Load-shedding technology can monitor power issues and reduce power consumption as factors arise, such as UPS battery activation temperate thresholds exceed pre-defined limits, etc.
Power-up sequencing ensures that if a critical power failure occurs, all of the outlets of a specific PDU are not all turned on at once, causing a detrimental power in-rush
Graceful shutdown agents can be implemented to perform clean OS shutdown when the need to remove power arises
