Remote Site Challenges
• 90% of employees work away from HQ
• Remote/Branch offices are growing by 11% annually
• Lack of on-site IT and facilities support personnel at remote
locations (<20%)
• Proliferation of distributed applications
• Increasing expense for ‘truck rolls” and 3rd -party calls

An Assessment: Basic, Metered, Monitored and Switched Power

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 Distribution Hardware
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 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

Proven ROI of Remote Power Solutions

Switched Power 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

Plotting it Out
Deliver clean, reliable power to IT assets
Monitor power consumption
Gather and communicate information on power anomalies, changes and issues
Ability to react to changes in system status, environment, etc.

Dispelling the Myths of Remote Power Management
DirectNET Confidential © 2007 DirectNET, Inc. All rights reserved.
Myth #1:Remote Power Can Impact Overall Reliability
• What happens if the intelligence fails? • Do my outlets lose power? • Do I lose the ability to access my power devices?

Myth #2: Remote Power Solutions Can’t Integrate with Existing Management Tools
• How can I arrive at an integrated solution with a single interface or console?
• How do I tie all of the management components together for ease of use?

Myth #3: Intelligent power doesn’t provide the real power needs for my Data Center
• Can I accommodate 3-phase power provisioning? • Can I control more than one circuit at the same time
through the same interface? • How scalable are those solutions when I need to grow?

Myth# 4: Intelligent Power Isn’t Worth the Investment
• Why are these so much more expensive than traditional PDU’s?
• How can I compare initial investment with true ROI and reduced TCO and IT management?
