The formula to calculate the Availability (A) is:

\[ \text{A} = \frac{\text{UT}}{\text{UT} + \text{DT}} \times 100 \]

What is Percentage Availability?

Percentage availability is a measure of the total time a system is operational compared to the total possible time it could be operational. It is a ratio of uptime to the sum of uptime and downtime, expressed as a percentage. High availability indicates that the system is reliable and experiences minimal downtime.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Availability:

\[ \text{A} = \frac{720}{720 + 8} \times 100 = \frac{720}{728} \times 100 = 98.90\% \]

The Availability is 98.90%.
