Question 1
IntermediateDiscover Customer Infrastructure and Requirements · Requirements discovery and workload characterization
An architect is sizing a new PowerScale solution for a healthcare customer. The workload consists of a Picture Archiving and Communication System (PACS). The customer has 4 PB of existing image data that is rarely accessed after 90 days, but they generate about 5 TB of new, highly active data daily that requires sub-millisecond latency for immediate physician review. Which node architecture best meets these requirements while optimizing for cost?
Answer and explanation
Correct answer: B
This is the optimal design. The highly active new data requiring sub-millisecond latency is best suited for F-series (all-flash) nodes. The massive 4 PB of rarely accessed data is best suited for A-series (archive) nodes to keep costs down. SmartPools is the OneFS feature that automates the tiering of this data based on age or access patterns.
