Question: A managment system has an overall availability of 99.99%. Calculate the minutes of downtime can be expected in a typical week, assuming uniform distribution of failures?
A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modelling techniques.
Mean Time to Repair (MTTR)
Mean Time to Repair (or Recover) is the average (expected) time taken to repair a failed module.
This time includes the time it takes to detect the defect, the time it takes to bring a repair man onsite, and the time it takes to physically repair the failed module.
Mean Time between Failures (MTBF)
Mean Time between Failures is the average (expected) time between two successive failures of a component. It is a basic measure of a system’s reliability and availability and is usually represented as units of hours.
The below formula indicate show to calculate the availablity :
Availability = MTBF/MTBF + MTTR
