HPE Server Solutions — Question 28

A customer needs a server infrastructure update for its Hadoop HBase solution. The HBase maximum dataset size will be 120TB.
To host HBase, the architect is planning three HPE Moonshot 1500 chassis that are fully populated with cartridges. The populated chassis provide the following in total:
✑ 135 processors with 4 2.9GHz cares each
✑ 4. 32TB RAM
✑ 64.8TB local storage on SSDs
Which aspect or the design is under provisioned and is likely to cause performance to be degraded to one-tenth or even one-hundredth of its potential?

Answer options

• A. number of cores per processor
• B. number of processors
• C. amount of local storage on SSDs
• D. amount of RAM

Correct answer: C

Explanation

The correct answer is C, as the local storage on SSDs at 64.8TB is insufficient for the 120TB dataset size, which can lead to performance bottlenecks. The number of cores per processor and the number of processors are adequate for handling the workload, and the amount of RAM is also sufficient for typical HBase operations.
