Benefits of Connecting Each Power Supply to a Separate UPS Unit

B.

The correct answer to this question is B. Fault tolerance.

A blade server chassis typically contains multiple servers or "blades" in a single enclosure. Each blade server typically requires its own power supply to operate. A blade server chassis can have one or more power supplies, depending on the model and configuration.

When two power supplies are present, connecting each power supply to a separate uninterruptible power supply (UPS) unit can provide a benefit called fault tolerance. Fault tolerance is the ability of a system to continue operating in the event of a component failure.

If one power supply were to fail, the other power supply connected to a separate UPS unit would continue to provide power to the blade server chassis. This helps to ensure that the servers or blades within the chassis remain operational, even in the event of a power outage or other power-related issue.

This is an important consideration for mission-critical applications or services that require high availability and uptime. By connecting each power supply to a separate UPS unit, a technician can help to minimize the risk of downtime and ensure that the blade server chassis remains operational even in the event of a power failure or other issue.

To summarize, the benefit of connecting each power supply to a separate UPS unit in a blade server chassis is fault tolerance, which helps to ensure that the servers within the chassis remain operational in the event of a power-related issue.
