1. Proactively Managing Your Data Center Infrastructure POWER -- COOLING -- MAINTENANCE

3. Data Center Cooling

4. Other Issues Found in Data Centers

5. Maintaining Data Centers

7. Key Issues Power – More than 50% of power going into a typical data center goes to the power and cooling systems –NOT to the IT loads Every kW saved in a data center saves about $1,000 per year Cooling – Legacy data centers can be overcooled by up to 2.6 times of the required capacity For each raise in set point – you can save 4% off the cost of running the unit Maintenance Preventive – routine scheduled maintenance Predictive – Infrared scanning and battery trending

8. Polling Question Which of the three key points just listed affect you most or are of most interested to you?

11. Common Power Problems Found in Legacy Data Centers Insufficient power capacity to support higher load densities – can lead to excessive branch circuits and overloading. Insufficient quantity of breaker positions. Distribution panels & PDU’s were not specified for dual power supply servers and 3-phase power supplies. Unexpected load drop with dual power supply servers. Electrical design has single power path and/or single points of failure.

12. Common Power Problems Found in Legacy Data Centers Dropped load due to PDU failure or tripped circuit breakers. Mismanagement of load utilization on redundant PDU’s and circuits. UPS dropped load during utility power outage. UPS batteries not monitored or maintained properly. Generator not maintained properly.

14. 2N UPS distribution

15. Benchmark is:Med density 5–10 kW/rack High density > 10 kw/rack

16. Legacy Data Center Power Power design based ontotal kW N or N+1 UPS redundancy N UPS distribution redundancy Benchmark is 100 watts/sq ft or 3 kW/rack

18. N UPS distribution

19. Benchmark is:Med density 5–10 kW/rack High density > 10 kW/rack

20. Polling Question Do you have growth restriction due to the amount of available power?

24. As racks require more power, replacing single-phase circuits with larger capacity, three-phase circuits can reduce breaker space requirements.

26. Common Cooling Issues Found in Legacy Data Centers Traditional floor mounted CRAC unit designs are insufficient for loads exceeding 5kW per rack. CRAC units misaligned with hot aisles - leads to hot air mixing, cooling ineffectiveness and inefficiency.

27. Common Cooling Issues Found in Legacy Data Centers Sub-floor air plenums choked off due to excessive cabling, limiting airflow through perforated floor tiles. Improper location of high density rack - Causes hot spots due to insufficient supply airflow.

28. Common Cooling Issues Found in Legacy Data Centers Overcooling - excessive number of CRAC units running to cool “the hot spots”. Perforated floor tiles located in hot aisle and near CRAC units. Allows mixing of hot and cold air – reduces cooling system effectiveness and efficiency. Lack of blanking panels in data racks allows hot air to re-circulate to rack fronts and server inlets.

32. In row or overhead systems

35. Supply air delivery through raised access floor or ductwork

37. In row or overhead systems

38. Hot or cold aisle containment 23

39. Typical ModernData Center Layout Power equipment in Red Cooling equipment in Blue

40. Polling Question If you have cooling issues, please identify the related cause(s) below? 25

44. IT racks should be arranged in Hot Row – Cold Row layouts, with CRAC units positioned to efficiently capture the heated return air.

45. Perforated tiles should not be located near CRAC units.

47. Common Problems Found in Any Data Center Stranded Capacity Mismanagement of power - cooling – space utilization Upgrade of one infrastructure without looking at the big picture Unprotected EPO buttons Accidental actuation will shut the room down! Dry chemical fire extinguishers Dry chemical agent will destroy computer equipment – Clean agents only. 30

48. Common Problems Found in Any Data Center Excessive debris and dust Contaminate computer equipment Cause false fire suppression system alarms Wall / ceiling / floor penetrations Compromise cooling system effectiveness & fire suppression system integrity Generator impairment Not in “auto” Battery failure condition 31

49. Maintaining Data Center Infrastructure Preventive Maintenance Neglecting to maintain equipment or implementing improper maintenance procedures are two of the biggest reasons why mission critical equipment fails. Predictive Maintenance Maintain critical equipment at high performance levels and prevent failures that could cause unplanned downtime with catastrophic results. 32

50. Maintaining Data Center Infrastructure The management of a company’s assets is based on maximizing those assets (ROI) and getting the maximum benefit from assets based on cost Asset management includes Preventive Maintenance In today’s critical environments, IT service continuity is a high priority Downtime is measured Emphasis on planning, preparedness, and adoption of best practice standards

52. Allows equipment to run more efficiently and can minimize energy consumption up to 5% less

54. Can help identify problems before they become headlines.Pictured here is a damaged UPS inverter assembly, the damage happened when one of the aging capacitors blew; this is the type of damage that can occur if your UPS isn’t properly maintained.

55. Polling Question With Maintenance being key to preventing down time, which type of service contract do you prefer?

60. Hourly Impact / System Outages A Meta Group study identified the hourly impact on different organizations to system outages. Source Meta Practice

62. Preventive maintenance activities include partial or complete overhauls at specified periods and recording trends.
