Data Centers

JDRM Engineer’s data center experience includes designing data centers providing geo-redundancy as well as the first Green Data Center in a University in Ohio. Our expertise spans in-row cooling and redundant systems, underfloor air distribution, fire suppression systems and more across the entire spectrum of organizational needs, from healthcare to industrial, educational to corporate internet/phone/entertainment providers. Our technological capabilities and experience empowers our clients to do more and be more for their clients.

Check out our Case Study for Magna where we consolidated multiple data centers into a tight space in their new corporate office building.

  • 100% redundant generator back up (2N design) for parallel operation
  • Multiple automatic transfer switches for redundant power distribution

Mechanical system upgrades included:

  • Addition of 100% redundant air cooled chiller incorporating waterside economizer with free-cooling component designed for extreme low temperature operation
  • Redundant chilled water system pumps with VFD’s
  • Expansion of building chilled water loop to accommodate extension
  • Phased approach to data center cooling upgrades
  • In-row chilled water cooling with containment implemented in data center to supplement and enhance existing air handling system
  • DCIM software system implemented for data center utility monitoring

Internet, Communications and Entertainment Provider – GeoRedundancy/Expansion Facility

Local Service Provider to new geo-redundant data center

  • Building designed to withstand F5 tornado
  • Existing 3,900 sq ft computer room ‘white’ space
  • Existing redundant air handling systems in electrical/service spaces
  • Existing data center provisioned with redundant CRAC/Drycooler systems.

Long term planning includes

Mechanical

  • Replacement of existing CRAC/Drycoolers with central chilled water plant (100%) redundant air cooled chillers with waterside economizer for low ambient operation and free-cooling opportunities
  • Computer space reconfigured with in-row cooling, hot/cold aisle configuration and hot aisle containment
  • DCIM incorporated into space and utility monitoring

Electrical

  • Upgrade building electrical service to permit installation of redundant transformers
  • Design of 100% emergency generation redundancy
  • Design of complete A/B electrical distribution throughout the Data Center and all critical equipment components

Building

  • Incorporation of complete building automation/monitoring system upgrade to provide enterprise level of service
  • Incorporation of complete building access control and CCTV system upgrades to provide enterprise level of service and remote monitoring
  • Biometrics and multilevel of building access/security provisions
  • Existing Halon fire protection system will be upgraded with new FM200 system

The University of Toledo

2016 Main Campus Upgrades Case Study

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
