TSYS Group - HQ data center documentation - power

Introduction

This article covers the electrical power setup for the HQ data center. We've grown it over time, bringing online more and more protected capacity as we got good deals on UPS/batteries etc and have added additional load.

Circuits

The server room is fed by two 20amp circuits:

  • Circuit 8a serving:

    • dedicated air conditioner (see our cooling article for details on that)
    • vm(1-3) servers
    • network equipment
    • overhead and led lighting
  • Circuit (xx) serving:

    • pfv-stor1/stor2 enclosures and drive arrays
    • vm(4-6)

(future plan)

  • Bring in circuit (xx) (currently serving front porch outlet) serving:
    • rackrental rentable equipment

Outlets

We have upgraded the standard 15amp outlets that came with the facility ,to 20amp outlets. This allows us to run a full 15amps sustained load (on 20amp circuits)

Surge Protectors

We utilize GE surge protectors , rated for 15amps. They are about $50.00 apiece. These are placed upstream of the UPS units (between the wall outlet and the UPS extension cord).

Extension cords

We do not have outlets close to the UPS stack. We utilize 15amp rated extension cords (from the surge protectors) to feed the UPS inputs.
