1 Challenges in optimizing data center utilization Data CentersChallenges in optimizing data center utilization
2 About Héctor Principal, Diaz Consulting Héctor R. Díaz Board of Directors, Data Center InstitutePresident, AFCOM Denver ChapterM:At Oracle managed over 1M SF of DC space, 80 MW power: Over 1,000 “labs”, 10 Enterprise DCs,
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 ft2 commercial data center will cost about $110M to build.That is about $3,100 / ft2Compare that to $100 - $150 / ft2 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 ITOperating at 85% capacity@9¢/kW energy costPUE of 1.2
6 Optimization Challenges Cost accountingSpace & power utilizationCapacity planningEnergy managementOutsourcing
7 Cost AccountingYou probably don’t know how much it is costing you!
8 Cost accounting strategies Boil everything down to MRC in Tier levelKnow 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 timeSeasonal variations for cooling loadsMore expensive for an empty data center
10 Typical cost of compute For a large Enterprise (economies of scale apply) Tier III$235 - $300 / kW MRCFor 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 don’t 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 ft2/rack)Set-up a space & power governance programMust pre-authorize HW intake to data centerMust follow-through with decommissioning equipmentNo orphaned servers!
13 Typical space & power utilization ft2 of floor space/rack equivalent unitTypical data centers consume kW/RackSome higher density designs 8kW/Rack up to kW/RackDon’t use watts/ft2
14 Capacity PlanningYou probably don’t know how much you are going to need!
15 Capacity planning strategies Detailed quarterly forecast (new and decommissioned HW)Project 2-3 yearsPublish a dashboardAdd feedback loop (actual vs. forecast)Enforce decommissioning! (avoid orphan HW)
17 Capacity planning benefits Improved quality of forecast over timeReduced CAPEX if you can delay build out of new data centerBetter decision support
18 Energy Management You are probably spending too much! You probably don’t know your PUE (Power Utilization Efficiency)You are probably running too cold!
19 Energy management strategies Measure and track your PUEUse ASHRAE’s new recommended operating temperatures.See Green Greed paper on ROI of cooling sys improvements
20 Energy Management ROIGenerally 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 OutsourcingYou are probably not benefiting from outsourcing!
23 Outsourcing strategies Consider colocationYou 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 options2MW is ~ 500 racks at 4kW/rack or 333 racks at 6kW. Say 400 5kW racksAt 25 ft2/rack that is 10,000 ft2 of “white space”!
