What factors are causing the increased latency in Cohesity's SmartFiles file access operations this quarter?

Introduction

Increased latency in Cohesity's SmartFiles file access operations this quarter presents a critical challenge that demands immediate attention. To address this issue, I'll employ a systematic approach to identify, validate, and resolve the root cause while considering both short-term fixes and long-term strategic implications.

My analysis will follow a structured framework, beginning with clarifying questions to establish context, followed by a thorough examination of potential external factors. We'll then delve into the product's user journey, break down the relevant metrics, gather and prioritize data, form hypotheses, conduct root cause analysis, and finally propose validation methods and next steps.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the system. Has there been any significant update or deployment to SmartFiles in the past quarter?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a major update. Impact on approach: If yes, we'd focus on the changes made in that update.

• Considering user segments, I'm wondering if this latency increase is uniform across all users. Are we seeing this issue across all customer types and file sizes, or is it more pronounced in specific segments?

Why it matters: Helps narrow down potential causes and affected areas. Expected answer: The issue is more prevalent in enterprise customers with large files. Impact on approach: If segmented, we'd investigate factors specific to those segments.

• Given the nature of file access operations, I'm curious about the infrastructure. Have there been any changes in our data center locations or network configurations recently?

Why it matters: Infrastructure changes can significantly impact latency. Expected answer: No major infrastructure changes. Impact on approach: If no changes, we'd focus more on software and user behavior.

• Thinking about measurement accuracy, I want to confirm our metrics. Has there been any change in how we measure or define latency for SmartFiles operations?

Why it matters: Ensures we're comparing apples to apples in our analysis. Expected answer: No changes in measurement methodology. Impact on approach: If changed, we'd need to recalibrate our baseline for comparison.
