A customer needs a solution to run a read-intensive workload. You propose the following configuration: HPE ProLiant DL380 Gen10 server HPE Smart Array P408e-p SR 6 SFF SAS HDD drives 1 SSD drive…

Question

Options

• AHPE 12Gb SAS Expander
• BHPE Secure Encryption
• CHPE SmartCache
• DHPE SSD Smart Path

• A
  3% (1)
• B
  10% (4)
• C
  79% (31)
• D
  8% (3)

Explanation

HPE SmartCache (C) is correct because it uses the single SSD drive as a read cache in front of the HDD array - exactly matching the scenario's constraint of minimizing new SSD investment while lowering read latency. It's a software-defined caching layer built into the Smart Array controller that automatically promotes frequently accessed "hot" data to the faster SSD, dramatically reducing read latency for read-intensive workloads without requiring a full SSD array.

Why the distractors are wrong:

• A (12Gb SAS Expander) increases the number of drive connections and bandwidth, not cache acceleration - it doesn't lower latency for existing drives.
• B (Secure Encryption) is a data-at-rest encryption feature; it adds overhead rather than improving performance.
• D (SSD Smart Path) is an I/O acceleration path that bypasses the controller firmware for all-SSD configurations - it doesn't apply when the target storage is HDDs.

Memory tip: Think "SmartCache = Smart use of a small SSD to Cache HDD reads." The key phrase in any exam question that points to SmartCache is the combination of existing HDDs + one SSD + read-heavy workload + cost constraint - it's the "do more with less SSD" technology.
