  • The US EPA estimates that US data centers reported this snowballing growth of data center power to Congress in 2006 and that this will increase if no action is taken.[CLICK x 1 – Other animations are AUTO]In the meantime, the cost to build a new data center has risen exponentially – over 1150% since the early 1990s. For many, building a new data center is not an option. Energy Management will be a key business need.It costs more to run data center than to buy IT equipment – some companies note a 7-times increase in power requirements from 1998-2005.July 2006, a CIO Insight Magazine article noted that up to 40% of the operating costs of a building that houses a data center might be power- and cooling-related. Nov. 2005 article in the Wall Street Journal noted that some medium-sized companies experienced a seven-fold increase in power requirements from 1998-2005. And over that time, the electrical costs to run those data centers shot up from $10k/month to $40K/month. In 2008, 59% of IT managers surveyed by AFCOM (data center manager’s association) said that their biggest worry is that equipment is purchased without concern for power and cooling*APC internal research Source: Energy Information Administration: International Total Primary Energy Consumption and Energy Intensity (2006) website.

  • Total electric power use on earth in 2008 was estimated to be 17,096 TWh (Terawatt hours).[CLICK] Data centers energy consumption data is probably 2% of the world’s electricity (some reports say not 2% but 8%). [CLICK] Due to poor design practices, one-third of that 2% is wasted due to the inefficiency of the traditional data center physical infrastructure… compared to what is possible for the same cost (this estimate is base on our experience). [CLICK] So just by doing smarter designs, we could save 1/3 of the energy consumption. This would amount to 27 TWh (Terawatt hours). This is more than the entire installed capacity of solar power available on the grid today. The total worldwide energy generated by Photovoltaic was about 26TWhr. Relative to the energy capacity for wind power and electricity consumption in the US, the potential energy savings available now is still significant.
  • Key point: This industry has a widely accepted energy measurement and improvement standard!Speaker note: Do NOT go into PUE detail—keep with the high-level theme of measuring energy performance against an accepted standard.[CLICK] BUT, customers MUST begin to measure before they can make improvements to compare against the benchmark standard.Customer motivation: With improvement against the benchmark of PUE & EnergyStar, customers can apply for special funding, tax credits, incentives, rebates, etc (from government and utilities).
  • Software Management is our strongest Schneider-wide offer in this space. Different management solutions for different business needs that affect the data center.Recall: The customer MUST measure their energy use against the standard that is established & widely accepted for the data center.
  • S+I speaker notes: Here we can identify the core purposes of the different Schneider software management platforms as they relate to data center monitoring and automation. They are NOT mutually exclusive, but rather serve different purposes and often different stakeholders within the business.Additional background notes from Kevin Brown, author of APC White Paper #104.This table helps to differentiate some of the mainstream Monitoring & Automation subsystems in terms of their primary and secondary functions.The facility power management subsystem provides detailed insight into the status and operation of the entire electrical distribution network (from utility feeds, to transformers, to PDUs, to racks) within a building, often including the data center. Electrical engineering staff and consultants utilize this subsystem to manage the electrical distribution network. The key functions provided by this type of subsystem include power monitoring of current conditions (critical and non-critical load), power alarming, and “power analytics”. These functions support critical activities such as notification of and response to electrical network problems, maintenance (planned and unplanned), capacity planning, facility expansion / retro-fit projects, energy efficiency projects, power quality analysis, and power reliability analysis.
  • S+I speaker notes: Here we can see how the ITB uses ISX Operations to complement the ISX Central, Power and Buildings management offers with data center infrastructure decision-making tools. This software uses the input from ISX Central to enable planning and implementation decisions to be made in a logical manner. Again, it is only as useful as the whole energy management view.Additional background notes from Kevin Brown, author of APC White Paper #104:This table helps to differentiate some of the mainstream planning and implementation subsystems in terms of their primary and secondary functions.Facility asset management – This subsystem allows for :management of asset deployment, generation of facility-relation parts specifications, calibration, costing and tracking of building equipment assets. Facility capacity management – This subsystem aids facilities staff to plan both moves and changes within the mechanical and electrical rooms, by providing real-time measurements of energy consumption and water flows in addition to the project impact of changes to the power and cooling infrastructure.IT room workflow management – This subsystem facilitates the execution of equipment additions, moves, and changes by presenting a hierarchical overview of data center locations, including global and local views and from groups to single assets. IT room capacity management – From a power consumption efficiency perspective, the system identifies the optimal physical location for power, cooling, and rack-based IT equipment.The speaker notes continue on next page; the following slide is hidden in presentation mode.
