Which of the following would enable a data center to remain operational through a multiday power outage?
Generator
A generator provides a reliable backup power source, allowing a data center to maintain operations during extended power outages by supplying electricity until the primary power is restored.
Generators are designed to produce electricity for prolonged periods, making them suitable for multiday outages. They can run on various fuels and are essential for ensuring that critical infrastructure, like data centers, remains operational when the main power source fails.
An uninterruptible power supply (UPS) provides immediate backup power for short durations, typically ranging from a few minutes to several hours. While a UPS is crucial for protecting systems from brief outages and allowing for safe shutdowns, it is not designed to sustain operations over multiday periods.
Replication refers to the process of copying data from one location to another for redundancy and disaster recovery. While it enhances data availability and security, it does not provide a power solution, meaning it cannot keep a data center operational during a power outage.
Parallel processing involves using multiple processors to execute tasks simultaneously, improving computational efficiency. However, it does not address power supply issues; thus, it cannot ensure that a data center remains functional during a power outage, regardless of how processing tasks are managed.
To sustain operations through a multiday power outage, a generator is the most effective solution, as it can supply continuous power over extended periods. Other options, while valuable for different aspects of data center management, do not provide the necessary long-term electricity supply needed during a significant power disruption.
