HPE Server Solutions — Question 30

Which statement describes the availability metrics for an HPE system’s high availability?

Answer options

• A. All standard HPE servers are designed for 99.9999% availability.
• B. A system consisting of HPE standard servers with an availability of 99.9999% and a storage with an availability of 99.99% will have a combined availability of 99.99999%.
• C. A system with an availability of 99.99% can be expected to be inoperational for 6 minutes or fewer per year.
• D. A system with an availability of 99.999% will statistically not have an unscheduled downtime of more than 1 hour total in 10 years of operation.

Correct answer: B

Explanation

Option B is correct because it accurately calculates the combined availability of two systems with different availability metrics. Options A, C, and D provide misleading information regarding the availability percentages and their implications, either overestimating or misrepresenting the operational downtime expected.
