Suggested answer: C

Explanation:

For a four X-Brick XtremIO X1 cluster, the total number of Power Distribution Panels (PDPs) that need to be connected to an electrical source is eight. This is based on the standard configuration for a four X-Brick cluster, which typically includes two power supplies per X-Brick and additional power supplies for the InfiniBand switches and other components1.

The process for connecting PDPs involves:

Identifying Power Requirements: Determine the power requirements for each component of the XtremIO X1 cluster, including X-Bricks and InfiniBand switches.

Allocating PDPs: Allocate the necessary number of PDPs based on the power requirements identified.

Connecting to Electrical Source: Connect each PDP to the electrical source, ensuring that the power distribution is balanced and meets the cluster's needs.

Verifying Power Supply: After connecting, verify that all components are receiving adequate power for operation.

Ensuring Redundancy: Ensure that there is redundancy in the power supply to protect against failures.
