Which statement describes the availability metrics for an HPE system’s high availability?
Which statement describes the availability metrics for an HPE system’s high availability?
A system with an availability of 99.999% suggests a very high level of reliability. If we consider five nines (99.999%) availability, this translates to roughly 5.26 minutes of downtime per year. Statistically, over a span of 10 years, this would sum up to about 52.6 minutes of downtime, which means it is reasonable to conclude that such a system would not have an unscheduled downtime of more than 1 hour in 10 years of operation.
A = Incorrect, Standalone HPE servers less than Four Nines B = Incorrect, Combined availability = lowest link in chain = 99.99% C = Incorrect, Four nines = 52.6 minutes downtime per year D = Correct Answer = Five nines = 5.26 minutes per year = 52.6 minutes in 10 years (statistically of course)
