Infrastructure Equipment

Infrastructure Equipment
       The purpose of this article is to provide a basis of "Best Practices of Infrastructure Equipment" for data center management and infrastructure. Local business reasons, local governmental code or other circumstances may mitigate the implementation of these best practices.


       It should be understood that the implementation of "Best Practices of Infrastructure Equipment" may require long term processes to be implemented, capital or expense funding and that the corrective actions will be ongoing. No work activities can be performed that have the potential to impact services without the prior approval of the appropriate management personnel.
  • Crankcase vapor recover systems on the diesel generators help keep the fins clean and heat transfer efficient
  • Fuel filters on the diesel generators should have water detection sensors installed
  • Having multiple fuel and oil filters with bypass valving on the diesel generators allows filter replacement while the generators are running
  • Re-circulation dampers reduce CFM air flow during cold weather
  • The installation of an insulating jacket of the diesel generator exhaust pipes will help to reduce ambient temperatures inside enclosed engine rooms
  • Compressed air should be piped directly to the diesel generator locations, with the proper quick connect fittings, to provide easy connection points for impact tools
  • The use of aircraft type of hose (metal braided exterior) vs. the rubber hoses on diesel generators will provide lengthened hose life
  • Diesel generator crankcase heaters should have cutoff valves installed for easy hose replacement
  • Pre-filled oil filter cartridges and an electric lube oil transfer pump can reduce downtime for an oil change
  • Engine start batteries should have clear plastic covers installed to prevent accidents
  • Permanently installed load banks will allow UPS systems and generators to be tested on a regular basis. Both UPS systems and generators should be tested on a monthly basis
  • A log sheet for recording UPS maintenance should be readily available, and preferably attached to the main UPS panels
  • All circuit breakers should be marked with a color coded schema to indicate whether they are normally open or closed
  • Main UPS and switch gear circuit breakers should be protected from accidental operation
  • Spare fuses should be stocked near the points where they are used
  • Environmental equipment systems labeling should be thorough, consistent and clear
  • Acid absorbent materials should be installed below UPS batteries
  • The installation of a permanent chain host in the UPS battery room will facilitate battery replacement and reduce the chance of personnel injury
  • Individual cell equalizers installed on the UPS batteries will ensure that each cell gets the exact charging voltage required for optimal battery performance
  • The use of a battery watering cart, complete with a bulk supply of de-ionized water and a small pump, will reduce the time required for topping off batteries
  • If battery lugs have multiple bolt holes, multiple bolts should be used to prevent constraint of current flow
  • Eye wash stations in the battery rooms should be interconnected to the alarm system, with appropriate organizations notified when the station is used
  • All piping should be numbered, color coded and flow direction noted
  • External connection points on the chilled water piping would allow the use of truck mounted chiller units in case of emergency
  • Breathing apparatus should be located in the proper area for the number of personnel assigned to the area
  • The condenser and cooling tower water control valves should have a manual override with a valve position indicator clearly marked
  • Cooling tower sump water should be checked on a daily basis for clearness. The use of a portable sand filter for the cooling towers is advantageous
  • An active biocide program should be initiated to prevent growth in the condensate drains for the CRAHs
  • Spill containment equipment and programs should be instituted in all spaces
  • Having an abnormal operating configurations or conditions posted on a status board available to all shifts will allow each shift to immediately be informed about any conditions
  • Each door exiting the equipment plants should have a telephone, flashlight, fire extinguisher and emergency procedures
  • Lockout and tag out tools are clearly labeled and stored in such a manner that any missing tool is apparent
  • Spare parts cabinets should be well stocked. Parts inventory sheets direct mechanics and engineers to the appropriate spares quickly
  • Fire stopping between spaces is consistent and well done
  • Fire detection heads should be on flexible conduit for easy relocation
  • Cooling condenser coils should be kept clean. A regular maintenance program should exist on the coils. Dirty coils reduce capacity
  • Cooling tower piping should be protected against freezing on cold days
