- Mean Time Between Failure: Explanation and Standards
- "Mean time between failure" is a reliability term used loosely throughout many industries and has become widely abused in some. Over the years the original meaning of this term has been altered which has led to confusion and cynicism. MTBF is largely based on assumptions and definition of failure and...

- Field MTBF Numbers: What Do They Really Mean?
- MTBF is an acronym for Mean Time Between Failures. In general, a higher MTBF number indicates a more reliable product. Beyond this simple definition, you’ll find a wide variety of special meanings. In the military/aerospace industries, MTBF is defined by a specific set of calculations. The formula for system longevity...

- Performing Effective MTBF Comparisons for Data Center Infrastructure
- Mean Time Between Failure (MTBF) is often proposed as a key decision making criterion when comparing data center infrastructure systems. Misleading values are often provided by vendors, leaving the user incapable of making a meaningful comparison. When the variables and assumptions behind the numbers are unknown or are misinterpreted, bad...

- MTBF Calculator (exe)
- Mean time between failures (MTBF) is the mean (average) time between failures of a system, the reciprocal of the failure rate in the special case when the failure rate is constant. Calculations of MTBF assume that a system is "renewed", i.e. fixed, after each failure, and then returned to service...

- MTBF Timer (zip)
- The MTBF Timer clocks the computer's up-time. You can use it to assess when it might be necessary to replace important components. The only known limitations are that standby and hibernate mode do not constitute power off, therefore the program calculates these periods as up-time. I don't consider this a...

- Understanding "Mean Time Between Failure"
- Mean Time Between Failure (MTBF) is a much-used management metric in IT both for discrete components as well as overall systems. It is an important metric to track in regard to system reliability. Even fault-tolerant servers fail. As the level of complexity and coupling increases, systemic failure due to the...

- The Role of Remote Management in Assuring IT Infrastructure Uptime
- Like it or not, businesses are becoming more and more dependent upon IT services and the infrastructure that supports them. Mean-Time-To-Repair (MTTR) and Mean-Time-Between-Failure (MTBF) are not only established SLA metrics in many environments, they have become almost visceral indicators of success and failure. Remote management can also contribute to...

- RAID technology is used to protect data as well as provide more efficient data access and capacity utilization with disk-based subsystems. By placing data on multiple disks, I/O (input/output) operations can overlap in a balanced way, improving performance. Using multiple disk drives increases the Mean Time Between Failure (MTBF), while...
