1 Data Centers Challenges in optimizing data center utilization

2 About Héctor Héctor R. Díaz Principal, Diaz Consulting Board of Directors, Data Center Institute President, AFCOM Denver Chapter M:

3 Market demand for data centers According to Microsoft, global construction will increase from about $50 billion today to about $78 billion by 2020

4 Data centers are expensive to build A 10MW 35,000 ft 2 commercial data center will cost about $110M to build. That is about $3,100 / ft 2 Compare that to $100 - $150 / ft 2 for a custom home in Denver

5 Data centers are expensive to operate The monthly electric power bill for a 10MW data center is about $551k ($6.6M/yr.) Network charges are very high as well. Data center infrastructure is the fastest growing cost of deploying IT

6 Optimization Challenges Cost accounting Space & power utilization Capacity planning Energy management Outsourcing

7 Cost Accounting You probably dont know how much it is costing you!

8 Cost accounting strategies Boil everything down to MRC in Tier level Know this number for every data center you own and for every colocation vendor you use. Easier to compute for dedicated data centers. More difficult but possible to compute for shared use buildings.

9 Cost accounting issues $/KW is not constant over time Seasonal variations for cooling loads More expensive for an empty data center

10 Typical cost of compute For a large Enterprise (economies of scale apply) Tier III $235 - $300 / kW MRC For small / medium Enterprise (no economies of scale) Tier II $300 - $400 /kW MRC; much higher for Tier III which is unlikely

11 Space & Power Utilization You dont know how much you are using!

12 Space & power utilization strategies Measure and publish utilization over time (both space and power) Know your metrics: (avg. kW/rack, avg ft 2 /rack) Set-up a space & power governance program Must pre-authorize HW intake to data center Must follow-through with decommissioning equipment No orphaned servers!

13 Typical space & power utilization ft 2 of floor space/rack equivalent unit Typical data centers consume kW/Rack Some higher density designs 8kW/Rack up to kW/Rack

14 Capacity Planning You probably dont know how much you are going to need!

15 Capacity planning strategies Detailed quarterly forecast (new and decommissioned HW) Project 2-3 years Publish a dashboard Add feedback loop (actual vs. forecast) Enforce decommissioning! (avoid orphan HW)

16 Capacity planning example

17 Capacity planning benefits Improved quality of forecast over time Reduced CAPEX if you can delay build out of new data center Better decision support

18 Energy Management You are probably spending too much! You probably dont know your PUE (Power Utilization Efficiency) You are probably running too cold!

19 Energy management strategies Measure and track your PUE Use ASHRAEs new recommended operating temperatures. See Green Greed paper on ROI of cooling sys improvements

20 Energy Management ROI Generally speaking, for every 1.8°F that you raise the temperature in your data center, you save 2-4% of your total energy bill.

21 Green Grid Recommendations Install OEM variable speed drives (VSDs) in all computer room air handlers (CRAHs). Upgrade older CRAH units with newer more efficient models. Improve rack airflow management by adding baffles and blanking panels, which improve isolation of hot and cold air aisles. Reposition the CRAH temperature/humidity sensors from the inlets of the CRAHs to the front of the IT equipment racks. Adjust the temperature set-points of the CRAH sensors and the chiller units.

22 Outsourcing You are probably not benefiting from outsourcing!

23 Outsourcing strategies Consider colocation You cannot build and operate anything smaller than a 2MW data center for less than what you would pay for colocation. (For the same Tier & service levels) Consider other outsourcing options

24 The outsourcing spectrum Application Middleware Operating System IT Physical Infrastructure Virtual Infrastructure Physical Hardware Data Center Environment BYODC ColocationManaged HostingSaaSPaaS IaaS
