Dell EMC Specialist – Systems Administrator, PowerStore — Question 14

A company has a 4-node Isilon H600 cluster dedicated for a high-performance workflow. The administrator wants to convert their cluster SSD strategy from L3 cache to use the SSDs for metadata acceleration.
What should be considered?

Answer options

• A. Migration of data and metadata from the SSDs to HDDs can take hours.
• B. Once enabled, the L3 cache cannot be disabled without support assistance.
• C. Converting to use SSDs for metadata acceleration turns off prefetching.
• D. Deselecting L3 cache for an SSD strategy has no impact to the workflow.

Correct answer: A

Explanation

Option A is correct because migrating data and metadata can indeed be a time-consuming process. Option B is incorrect since the L3 cache can be disabled with support, not just enabled. Option C is wrong because converting to SSDs for metadata acceleration does not disable prefetching. Option D is false because deselecting L3 cache can potentially impact performance despite the claim.
