The University of Toledo Data Center Upgrades
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.
Dedicated computer room temperature/building automation system communicates with University and dedicated DCIM software for total system and space monitoring.
Electrical System Upgrades
Implementation of 2nd UPS unit for incorporation into existing parallel system design. Capacity will provide 100% redundancy.
Expansion of existing battery monitoring system to new UPS
Installation of 2nd emergency generator to provide selectivity and 100% building redundancy.
New Computer Room electrical distribution to incorporate
Dedicated independent A/B services to in-row cooling units
Dedicated independent service to chillers from separate transfer switch distribution
Dedicated independent A/B services to end of row power distribution units (one on each end of row)
Dedicated and independent local power distribution for legacy equipment and local power needs in the computer room
All electrical, not including row power distribution units, are located outside of the computer room space
Room lighting upgrades to incorporate LED lighting and strategic switching to accommodate flexibility and energy saving opportunities.
Room grounding system will be enhanced to accommodate proposed room re-configuration
Building Upgrades
Computer Room access floor removed
Computer room ceiling replaced
Computer Room fire protection system upgraded
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
Building
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
