Asset reliability in data centers: 5 key metrics for success

July 21, 2023

Ensuring asset reliability is essential for the smooth operation of data centers. While many key performance indicators (KPIs) can be set to measure productivity initiatives, it’s tough to truly know how your teams are performing without knowing how reliable your assets are. To solve for this, data center operators need to measure and analyze key metrics that provide insights into the performance and lifespan of their assets. By doing so, they can make data-driven decisions on processes, proactive and preventative maintenance, replacements, and upgrades, ultimately improving overall reliability and performance. Here are five key metrics that can help assess the reliability of assets within data centers.

5 Key Asset Reliability Metrics

1. Failures Per Asset

One crucial metric for evaluating asset reliability is the number of equipment failures per asset. By keeping track of the frequency at which assets experience malfunctions or breakdowns, data center operators can gain valuable insights into asset performance and reliability. This metric allows them to identify problematic assets and implement proactive maintenance strategies to improve overall reliability and performance.

2. Age at Failure

Another important metric is the age at which failures begin to occur. By analyzing the age at failure, data center operators can assess the lifespan of their assets and make data-driven decisions regarding maintenance, replacement, and upgrades. This metric also helps in predicting future failures and allows for proactive measures and maintenance to prevent disruptions. By understanding the age at which failures occur, operators can be prepared with the right parts and process and implement strategies to improve overall asset reliability.

3. Mean Time Between Failures (MTBF)

MTBF provides insights into the average time between failures, allowing operators to assess the overall reliability of their equipment. By calculating MTBF, operators can make informed decisions on preventative maintenance, upgrades, and capital planning for replacements. Monitoring and analyzing MTBF help operators in identifying potential issues and addressing them proactively, reducing downtime and improving overall performance.

4. Failure Mode and Root Cause

Knowing when to expect your assets to fail is great, but understanding how they’ll fail is important to getting ahead of any problems and being prepared to treat the root cause. Failure modes refer to specific ways in which assets fail, such as wear and tear or software glitches. Identifying these modes provides insights into areas needing improvement. Determining root causes involves investigating factors like design flaws or inadequate maintenance. Addressing root causes allows for corrective actions and data-driven decisions on your maintenance team’s processes and advance notice for capital planning. Understanding failure modes and root causes also optimizes spare parts inventory and reduces downtime, ultimately improving asset reliability, maintenance practices, and overall data center performance.

5. Change in Failure Rate Over Time or End of Life

By monitoring the change in failure rate over time you can see a trend and know when an asset is coming up on the end of its useful life cycle. This proactive approach prevents disruptions and optimizes asset management, empowering your data center to make better informed decisions when planning capital budgets in the coming months or even years. Analyzing failure rate patterns also helps detect underlying issues and take prompt corrective action. By understanding the lifespan of assets, operators can make ensure the smooth operation of the data center.

Wrapping Up

Maintaining asset reliability is crucial for the smooth operation and continuous uptime of data centers. By measuring and analyzing these key metrics—failures per asset, age at failure, MTBF, failure mode and root cause, and change in failure rate over time—operators can gain valuable insights into the performance, lifespan, and potential issues of their assets. These metrics allow for data-driven decisions on maintenance procedures, spare parts, replacements, capital planning, and more, ultimately improving your data center’s overall reliability and performance and keeping your customers very happy.
