Nearly 64 percent of data center managers expect to run out of data center power capacity by 2011, but amidst free-falling IT budgets, many lack the resources to keep up with future demand. Fortunately, there are cost-effective measures organizations can take to optimize and increase capacity in the power systems they already own. This presentation from Emerson Network Power's Business Innovators webcast series demonstrates strategies for discovering and unlocking the capacity in your data center's power infrastructure.

  • Function: Facility monitoring system (SiteScan) provides data on real-time capacity of physical infrastructure to CMDB CMDB maps relationships between facility equipment and managed objects in the IT domain, in this case, individual racks Aperture provides the user interface to display capacity mapped to racks and locations within racks
  • Function: IBM Director sends power usage data reported by the servers to Aperture, which maps this data onto racks, PDUs, and UPS SiteScan sends data from the facility equipment to Aperture Aperture displays results from multiple sources The user compares data from multiple sources and makes judgments about how to translate future IT requirements into power and cooling needs based on historical data The user add components to the data center to create a scenario and project future requirements
  • Adaptive power systems can scale for capacity and be configured to meet changing availability requirements. On the left, we have a single UPS. We can add an additional UPS. I can take the by-pass out of this module and put it in a separate piece of gear. And I can go up to a 2N or 2N+1 system. And here maybe I'll have two buses. Or I can add redundancy on those buses. So in terms of tiers, we start with a basic UPS, add a redundant UPS, add some gear and make it concurrently maintainable, and then go to full Tier Four, fault-tolerant UPS system. Scalability wise, I can take that 80 kVA UPS and scale to 100, to 120 kVA. I can scale it and parallel it, or just parallel it as is. So that's what we're doing with UPS technology, especially at 200 kVA systems and below.

  • Strategies for Finding and Unlocking the Hidden Capacity in Your Data Center Infrastructure
    • Sizing data center power and cooling systems can feel like buying shoes for a fast-growing teenager: choose the size that fits today and you’ll be replacing a perfectly good pair of shoes in two months.
    • Fortunately, data center power and cooling systems are proving to be surprisingly adaptable. This session will help you determine how much “flex” exists within your data center infrastructure. We’ll show you how to assess the hidden capacity in your power and cooling systems and review strategies for unlocking this hidden capacity.
    • Whether you’re evaluating if your current facility can carry you into the future, or planning a new facility, this session will give you new insight into sizing – and growing – power and cooling capacity.

  • What is data center infrastructure management?
    • Data centers consist of multiple interrelated subsystems
      • Can be overwhelmingly complex for any but the smallest facilities
    • Objective is to deliver services at a targeted service level
      • Service Level Agreement (SLA) implies targets for availability and performance
    • Management of a large data center to the SLA at optimum cost can become intractable
      • One approach is to break down the task into smaller, manageable domains
      • The Data Center Physical Infrastructure (servers, storage, rack space) and the Critical Facilities (power, cooling) each comprise multiple domains
    • There is an opportunity to bridge the gap between the IT Physical Infrastructure, Critical Facilities and Data Center Service Management to optimize the data center
  • Scenario 1- Capacity view Facility IT SiteScan Aperture VISTA Deploy hardware without exceeding power, space, or cooling capacity VISTA shows available capacity for a proposed change SiteScan provides real-time data on power and cooling capacity  

      • A good starting point is kW per rack kW per rack x10 is approximately the watts/sq ft req’d 12kW per rack results in 120 watts/sq ft
      • Another method is using floor tiles 3500W per floor tile equates to about 90W per sq ft 3500W per floor tile equates to 1 ton of cooling per floor tile 3500W per floor tile equates to between 6 and 8 kW per rack

  • Considerations for sizing cooling
    • IT loads have a large variation in cooling and airflow requirements
      • Virtualization, power management, new equipment
    • Need to match cooling capacity with the IT load
      • Eliminates over cooling and improves cooling efficiency with reduced cycling

      • Raise the chilled water temperature above 45°F
    • Review ASHRAE guidelines
    • Consider a thermal assessment to help jump start the process
  • Baseline strategies for cooling efficiency: Seal the data center environment

    • Keep doors closed at all times
    • Use a vapor seal to isolate the data center atmosphere
  • Baseline strategies for cooling efficiency: Optimize airflow
    • Rack arrangement
