The University of Toledo

2010 Health Science and Main Campus Upgrades

Data center capacity was increased to meet increasing demands; the campus’ were connected via a fiber optic direct communication link providing network system redundancy.

Mechanical System Upgrades

Health Science Campus

  • Existing HVAC systems were made of redundant CRAC units connected into building/hospital central chilled water plant
  • New electrical room was provided with redundant air handling units connected into existing building chilled water system
  • Existing underfloor air distribution was enhanced by re-positioning floor supply grilles
  • Data cabinets were replaced and provided with dedicated exhaust connection into return air plenum
  • Existing CRAC units were updated to include extension of return air ductwork into ceiling plenum
  • Computer room ceiling was reconfigured to include return air provisions over the hot aisles as well as to incorporate dedicated data cabinet exhaust discharge

Main Campus

  • Existing Computer Room incorporates 2 CRAC units connected into building central chilled water system and 2 CRAC units with dedicated drycoolers.
  • Capacity is believed to be 100% redundant
  • Existing CRAC units utilized ceiling plenum with relief thru existing ceiling into the space
  • Further system modifications were deferred to future phases

Electrical System Upgrades

Health Science Campus

  • Emergency generation system design included provisions for 2 generators to operate in parallel; however, for this phase, only 1 generator was provided.
  • Dedicated emergency feeder from generator to new automatic transfer switch and distribution for Computer Room
  • Future space allocation has been identified for 2nd generator and paralleling switchgear
  • Computer Room electrical system was upgraded to include;
  • 1 new UPS with provisions for 2nd to parallel
  • Complete A/B buss power distribution thru new harmonic mitigating transformers, distribution equipment to overhead buss distribution to data cabinets


Health Science Campus

  • Room data cabinets were re-organized to provide complete hot-cold aisle configuration
  • Computer room fire protection was upgraded to new FM200 system

2016 Main Campus Upgrades

Data center re-configured complete with new cabinets, power distribution, cooling and more over a phased project implementation

Room configuration updated to hot/cold aisle arrangement; in-row cooling; hot aisle containment; end of row power redundant distribution; removal of raised floor; replacement of fire protection system; provision of dedicated computer room cooling system; implementation of DCIM throughout data center

Mechanical System Upgrades

  • Existing CRAC units replace in a phase fashion due to room phased implementation.
  • Dedicated new air cooled chiller(s) designed to be 100% redundant and include waterside economizer for free-cooling and low ambient operation
  • New piping, pumps, make-up, controls to permit isolated operation
  • Computer room incorporates in-row chilled water unit solution with hot aisle containment for module and space control.  Design to provide 2N design at chiller level and N+1 design at the row/module level.
