Which of the following is NOT a primary consideration for power management in a data center?

Cost reduction is often a secondary consideration in the context of power management for a data center, while the other options represent primary considerations.

Reliability is critical because data centers must ensure continuous operation with minimal downtime. A data center's power management system should be designed to provide unwavering power to support the infrastructure, which underscores the importance of reliability.

Capacity planning is equally crucial as it involves ensuring the data center has sufficient power resources to support current and future load demands. This process helps prevent overload situations and informs decisions regarding infrastructure upgrades or expansions.

Backup systems are essential as they provide an additional layer of security and reliability. In case of a primary power failure, backup systems, such as uninterruptible power supplies (UPS) and generators, ensure that operations can continue without interruption.

While cost reduction is an important aspect of overall operational efficiency and budgeting, it does not directly impact the critical elements of power management, which focus on ensuring reliability, capacity, and contingency planning through backup systems.
