Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this might be related to recent hardware changes. Have there been any modifications to the optical interconnect components in the last few months?

Why it matters: Hardware changes could directly impact power consumption. Expected answer: Yes, there were some component upgrades. Impact on approach: If confirmed, we'd focus on hardware-related hypotheses.

• Considering the magnitude of the increase, I'm wondering about the testing environment. Were these trials conducted under the same conditions as previous tests?

Why it matters: Environmental factors could significantly affect power consumption. Expected answer: The conditions were similar but not identical. Impact on approach: We'd need to investigate potential environmental influences.

• Given the customer-facing nature of these trials, I'm curious about the workload. Has there been any change in the type or volume of data being processed during these trials?

Why it matters: Workload changes could explain increased power consumption. Expected answer: Customers might be running more intensive workloads. Impact on approach: We'd need to analyze workload patterns and their impact.

• Thinking about measurement accuracy, I'm wondering if there have been any changes to the power monitoring systems or methodology?

Why it matters: Ensures we're comparing apples to apples in our measurements. Expected answer: No changes to monitoring systems. Impact on approach: If changed, we'd need to validate the new measurement system.
