Question

Certilyst · Accepted Answer

A Rationale: Power redundancy is essential in a network rack setup with four servers and four switches. Adding a second PDU ensures that if one PDU fails, the other can continue to supply power, preventing outages and maintaining system uptime.

Failed PSU monitoring refers to the ability to track the status of power supply units, which is not a reason for adding a second PDU. This functionality can typically be managed with monitoring systems integrated within the existing PDU.

Surge protection protects equipment from voltage spikes but does not necessitate a second PDU. Most PDUs come with built-in surge protection capabilities, making an additional PDU for this reason redundant.

Electricity conservation is not a valid reason to add a second PDU, as the primary objective of a second PDU focuses on maintaining power availability rather than reducing electricity consumption.
