Facility Power

Review the facility electrical power requirements for Exadata Cloud at Customer.

Review the following requirements:

  • Electrical work and installations must comply with applicable local, state, or national electrical codes.

  • Contact your facilities manager or qualified electrician to determine what type of power is supplied to the building.

  • To prevent catastrophic failures, design the input power sources to ensure adequate power is provided to the Power Distribution Units (PDUs). Dedicated AC breaker panels are required for all power circuits that supply power to the PDUs.

  • When planning for power distribution requirements, balance the power load between available AC supply branch circuits. In the United States and Canada, ensure that the overall system AC input current load does not exceed 80 percent of the branch circuit AC current rating.

  • PDU power cords are 4 m (13.12 feet) long, and 1 to 1.5 m (3.3 to 4.9 feet) of the cord will be routed within the rack cabinet. The installation site AC power receptacle must be within 2 m (6.6 feet) of the rack.

  • Provide a stable power source, such as an uninterruptible power supply (UPS) to reduce the possibility of component failures. If computer equipment is subjected to repeated power interruptions and fluctuations, then it is susceptible to a higher rate of component failure.

  • The Exadata Cloud at Customer cabinet is shipped with grounding-type power cords (three-wire). Always connect the cords to grounded power outlets. Because different grounding methods are used, depending on location, check the grounding type, and refer to documentation, such as IEC documents, for the correct grounding method.

  • Make sure that the facility administrator or qualified electrical engineer verifies the grounding method for the building, and performs the grounding work.
