Problem:

Our data center has a total of 65 computers. Each quarter we need to report to our customers the percentage of uptime for the data center.

If we are reporting for the months August, September, and October and there are 49 computers that are up 100% of the time, what is the percentage of computers available 100%.

If the total downtime of all 65 computers totals 2,435 minutes, what is the average downtime per computer per month?

What is the total uptime percentage?

Solution:

(49 65) x 100 = 75.38% computers available 100%

(2435 65) 3 = 12.49 min. average downtime/computers per month

(60 min. x 24 hrs.)(31 days + 30 days + 31 days) x 65 = 8,611,200 total possible computing minutes

8,611,200 - 2,435 = 8,608,765 total actual computing minutes

(8,608,765 8,611,200) x 100 = .9997 = 99.97% uptime
