Electrical Power

Learn about the electrical power specifications and requirements for Exadata Cloud at Customer.

Exadata Cloud at Customer can operate effectively over a wide range of voltages and frequencies. However, it must have a reliable power source. Damage may occur if the ranges are exceeded. Electrical disturbances such as the following may damage an Exadata Cloud at Customer:

  • Fluctuations caused by brownouts

  • Wide and rapid variations in input voltage levels or in input power frequency

  • Electrical storms

  • Faults in the distribution system, such as defective wiring

To protect the system, dedicated power distribution system and power-conditioning equipment should be used. Lightning arresters or power cables should be used to protect from electrical storms.

Each rack has two pre-installed Power Distribution Units (PDUs). The PDUs accept different power sources. You must select the type of PDU that meets the requirements for your data center.

Available PDUs

The following list outlines the available PDUs for Exadata Cloud at Customer depending on your region:

  • Americas, Japan, and Taiwan

    • Low-Voltage 15kVA Single-Phase

    • Low-Voltage 15kVA Three-Phase

    • Low-Voltage 22kVA Single-Phase

    • Low-Voltage 24kVA Three-Phase

  • Europe, the Middle East and Africa (EMEA), and Asia Pacific (APAC), except for Japan and Taiwan

    • High-Voltage 15kVA Three-Phase

    • High-Voltage 22kVA Single-Phase

    • High-Voltage 24kVA Three-Phase
