  • One of the ways offices and building managers have relied on to cool the IT equipment is through the building’s central air conditioner. There is a downside to this approach as building AC was designed for people. Traditional AC is designed to be run when the building is occupied and doesn’t have the performance or life span of a dedicated computer cooling system. In office environments, building air will likely be turned off when the building is unoccupied. Also building air allows for a large fluctuation in both temperature and humidity. When humidity levels get to high, condensation can appear or if levels are too low an electrostatic discharge can occur. Lastly, the building’s air is likely not supported by the generator. The main cooling plant requires a lot of electricity and the hospital may decide it is not a critical system, so during a power outage there will be no cooling.The solution to address these issues is a dedicated precision cooling system. These computer room air conditioners or CRAC’s are designed to be run 7 x 24 and have microprocessor controls which set precise temperature points and humidity ratios. An added benefit of CRAC’s is they have been designed for energy efficiency and utilize the latest in cooling technology like plug fans.Increasing heat densities is a major concern of health facilities. In a recent survey of healthcare providers, the number 1 IT concern was rising heat densities.
  • Fortifying Network Closets: Improving Patient Care and Doctor Satisfaction

    1. 1. Fortifying NetworkClosetsImproving Patient Care andDoctor Satisfaction Dan Draper Manager, Healthcare Industry Liebert Products
    2. 2. Agenda• Network closets in hospitals and ambulatory care facilities – Function and importance – Avoiding network downtime• Power fundamentals• Power best practices• Cooling fundamentals• Cooling best practices• Other areas of IT infrastructure in healthcare settings• Critical questions to ask• Q&A
    3. 3. Network closets• Computer room, network access room, wiring closet – Typically a 5x5, 6x6 or 8x8 room – Dedicated space containing networking and computing equipment • Routers • Switches • Bridges • Hubs – The equipment enabling data communications • Wireless • VOIP/ telecommunications • E-mail / Internet
    4. 4. Network closet differences Hospital Environment Ambulatory Environment Many closets, 1 per 10 beds Single closet Dedicated support: If in a health system, remotelyIT, Facilities, Network Services supported by parent hospital Emergency generator on site Likely, no emergency generator Routers, switches, hubs Routers, (maybe) servers and storage Many closets Higher heat from server / storage Increasing heat densities Downtime hurts IT acceptance Increasing need for power Lack of dedicated IT expertise
    5. 5. Why should we care? • Network Closet: the link to patient data Data StoragePatient Doctor Network IT Device Closet • If the closet is down, can’t access EMR, PACS, VOIP – Delays, inability to process patients, no orders, no billing – Remember: no more paper back up
    6. 6. IT equipment downtime • IT equipment needs electricity to run – When the power is off, IT won’t work – 6 ½ “momentary outages” per year • IT equipment produces heat – Heat destroys electronics – Every 10° increase over 80° F produces a 50% reduction in long-term reliability of IT hardwareNetwork closet’s IT infrastructure must befortified to ensure availability • Uninterruptible Power Supply (UPS) • Precision Cooling
    7. 7. UPS fundamentals • Instantaneous battery back-up – Ride through until generator assumes the load • Typically rack-mounted in network closets • Two design topologies – Line interactive UPS in a rack – Double conversion Back view
    8. 8. Line Interactive / Double Conversion Line Interactive UPS  Very efficient, volts in = volts out  Load sees a wide range of voltages – Ex: Sag from 120 volts to 100 volts – Critical load only running on 100 volts • If this were a light bulb it would flicker and dim – Battery turns on at 90 volts, load at 120 volts – 4 millisecond transfer to battery  Rebuilds voltage, always perfect Double Conversion UPS  Load always sees 120 volts – Ex: Sag from 120 volts to 100 volts – Double conversion changes the 100 to 120 – No Battery use until volts drop to 60 • Load never deviates from 120 volts – Zero transfer time to battery
    9. 9. Best practice: When to use which? Line Interactive Double Conversion Constant regulated output power Efficient Pro Instantaneous battery switchover Less expensive initially High reliability Load sees voltages sags Con Higher initial price More battery replacements Purchase $3,000 for a 3 kVA UPS $1,300 for a 3 kVA UPS Price Is there a generator present? Critical Key difference is how they deal with fluctuating power Question Do generators produce clean electricity? No! Ambulatory environment Hospital environmentWhen to use No generator Generator present Less critical loads Extremely critical loads
    10. 10. Is my UPS sized correctly? • Understand what the UPS nameplate means – UPS typically sized in VA (volt-amperes) – AC watts = volts x amps x power factor UPS Name Plate Power Factor AC Watts Available 1000 VA .7 700 1000 VA .75 750 1000 VA .9 900 – If you think your 1,000 VA UPS can support 1000 watts of computer equipment, you’re wrong – Know the power factor of different UPS models • Battery run time at different capacities
    11. 11. Focus on hospital network closet UPS • Dozens of closets = dozens of UPS – Difficult to maintain, high battery management – When loads grow, add more UPS – Likely redundant UPS • Distributed UPS Strategy Network – One small UPS in every closet UPS Closet – Ex Five 8 kVA UPS UPS Network Closet Network Utility Distribution UPS Closet Network UPS Closet Network UPS Closet Distributed: Typical UPS strategy in hospital network closets
    12. 12. Best practice: Centralized UPS • Centralized UPS Strategy – One large UPS covering multiple closets Reference Chart: Distributed – Ex One 40 kVA UPS (instead of five 8 kVA) – If UPS is initially over sized, easy to add loads • Instead of a 40 kVA UPS, install a 80 kVA UPS Network Closet Network Closet Network Utility UPS Distribution Closet Network Closet Centralized: Best practice among Network Closet new build and high IT growth hospitals
    13. 13. Distributed vs. centralized Distributed Centralized • Easier capital appropriation • Greater energy efficiencyAdvantages • Smaller individual footprint • Single system to service • Easy to install • Frees up rack / room space • Easy to relocate • Sized for future kVA requirements • Lower perceived cost • Lower UPS capital cost • Lower UPS operating cost • • Equipment room neededDisadvantage Utilizes vital rack space • Higher failure rate • Electrical contractor for installation • Lower energy efficiency • Up front capital allocation s • Individual batteries to service • Aggregate cost of total UPS higher TCO for centralized is 25% to 35% less than distributed
    14. 14. Precision Cooling Fundamentals • American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) – Recommends inlet temperature range of 64 to 80 degrees F – Humidity level (dew point) should fall within 42 to 59 degrees F • 2008 change: was 68-77 degrees and 40%-50% RH • Quick hits: – Inlet temperature, don’t go by a wall reading – Higher temps = more equipment fan use – 72 degrees is the norm, with 45% RH (data center avg. closets run warmer) • Most IT equipment has an upper operating temp of 95 - 100 degrees  What is precision cooling?  When do I need precision cooling?
    15. 15. Why traditional building A/C won’t cut it Comfort Cooling Precision Cooling Designed for people Designed for critical electronic • 2500 hrs / year operation equipment • Allow for a large range of • 8760 hrs / year operation fluctuations in temperature and (24 hours / 365 days) humidity • Microprocessor control of • High cost to operate temperature and humidity ratios • Energy efficient technology
    16. 16. When do I need precision cooling? • Too warm to work in comfortably • Switches / servers failing (too late!) • Over 1000 watts of heat • It all depends… – Room size, amount of IT – Existing air exchanges • Heat is a major problem in ambulatory network closets – Switch produces 1000 watts of heat, but what else is in the room? – Possibly servers and storage for local EMR – Building A/C turns off at night and in winter
    17. 17. Precision coolingAir cooled – most common solution • Heat will need to be rejected – Outdoor condenser • Other Options: Water, Glycol, Chilled Water  Cooling Best Practices – Save space, use overhead – Ceiling units not install directly above equipment Overhead 3.5 kW to 28 kW – Are Cooling units on emergency power? Integrated Rack – At least have a plan, think 2 kW to 14 kW about supply lines, install ducting today
    18. 18. More best practices • Physical security – HIPAA: “safeguard equipment from unauthorized physical access, tampering and theft” – Box fan in the open door way… No cooling = Open door = Security risk – Lack of cooling results in possible HIPAA violation – Solutions: Cooling and rack with a locking door
    19. 19. More best practices • Remote monitoring – Hospital systems have dozens of remote offices • IT Staff not physically on site – Infrastructure monitoring: power and environmental – Web interface using HTTP and SNMP support – Provides alarm notifications via email and text messaging – Address issues before they take the network down
