Reliability

Reliability

1. Consequences of unreliable systems

   • Consequences of unreliable computer systems can be measured with AVAIL and MTTF
     • AVAIL is the time that the system is available to the user or customer but taking out any planned downtime perhaps for maintenance.
     • MTTF stands for Mean Time To Failure

2. Reliability for computer systems is measured and it has a metric measure. It is how well a computer system does what it is expected to do before it fails.
