    Notes on slide 1

    STANDARD TECHWEB SLIDE **Please do not edit without consulting your project manager**

    Enterprise has an average of 8kW per rack. Will increase to 12kW by 2010. Enterprise is growing faster, but SMB is catching up.

    We want to make sure you understand the dynamics of power and cooling. For every watt of power used, equipment generates a watt of heat.

    A rack with 23kW of power generates 23kW of heat which requires the same amount of cooling used to cool a 2500 square foot home. IT talks in kilowatts, engineers and facilities managers talk in tons of cooling. As a rule of thumb, 3.5kW = 1 ton of cooling.

    This graph shows what happens if a cooling failure occurs at three different levels of room density. The three lines represent room densities at 150, 300 and 450 watts per square foot– 4.8, 9.6 and 14.4 kilowatts per rack, respectively. As time moves from left to right following a system interruption, temperature in the room rises more quickly in the higher density facilities. At densities of 150 Watts per square foot, it takes a room approximately 23 minutes to reach 40 degrees Celsius, about the limit for server specifications. At 450 Watts per square foot – which we are beginning to see in some installations-- the room heats to 40 degrees Celsius in about two minutes. The fact that 50 degrees can be reached in about 5 minutes leaves a variety of new factors to consider regarding facility design and human comfort. Although many server manufactures today spec out operating ranges of 10 to 35 degrees Celsius, as these processors heat up, they actually slow down the clock speed to reduce heating effects, which slows system performance. ASHRAE – the American Society of Heating and Refrigeration Engineers-- goes a step further by categorizing environments for Data Centers as a class 1 environment, which recommends a stable operating range of only 20 to 25 degrees Celsius, with a maximum allowable of 15 to 32 degrees Celsius. Your cooling system is far more critical than ever because availability can be compromised as heat densities rise. This is compounded if you are cooling a closed environment.

    SMBs: Get More with Less with Dynamic, Flexible IT Cooling - Presentation Transcript

    1. A bMighty Vendor Perspective’s Webcast Sponsored By SMBs: Get More with Less with Dynamic, Flexible IT Cooling
    2. Webcast Logistics
    3. Today’s Presenter Matt Kightlinger Director of Solutions Liebert Products and Services Emerson Network Power
    4. SMB Cooling Concerns and Constraints
    5. Average kW
      • The average kW per rack will increase 32% by 2010
        • Overall, the current average kW per rack is 6.27
        • Network closets and data centers less than 100 sq. ft. will see the biggest increase in kW per rack by 2010
          • 52% increase in kW for network closets
          • 38% increase in kW for data centers less than 100 sq. ft.

    6. Blade servers
      • The majority of SMB data centers do not have blade servers
        • An average of 46% of the data centers do not have blade servers and do not plan to add them
        • An average of 21% do not have blade servers but have plans to add them
        • An average of 32% are currently running blade servers
          • The majority falls into 1,000-2,500 sq. ft. sized data centers (56%)

    7. Issues experienced
      • Most SMB data centers have experienced some type of issue within the last two years
        • The most common issues are
          • Experienced an outage (50%)
          • Hot spots (49%)
          • Run out of cooling (46%)
        • 20% of respondents have not had any issues
      Source: Emerson Network Power SMB customer research, August 2008 
      • You have hot spots in your data center or racks
      • You are unable to take advantage of new IT technology (blade servers) or unused U space within your racks due to cooling constraints
      • You are adding IT or network equipment in spaces not designed to be a data center
      • You are using comfort cooling systems for critical IT spaces
      • You are consolidating servers but haven’t calculated the cooling demands for the new environment
      • You have difficulty keeping temperatures in the room at or below 78 °F
      • You have little to no cooling redundancy in you data center
      Warning signs that your infrastructure may not be as resilient as it needs to be
    9. An Introduction to IT Cooling

    11. 23 10 KW rack Requiring cooling needed for an average American home Heat Generated IT Equipment 10kW
      • Calculations:
      • 1kW = 3413 BTU/hr.
      • 1-Ton = 12,000 BTU/hr.
      • 3.5kW = 1-Ton of cooling
