Analyze and Optimize Storage Performance

An administrator is deploying a VDI solution. The workload will consist of persistent desktops in a dedicated storage container within a four-node cluster.

Storage optimizations must be configured on the dedicated storage container to provide optimal performance, including during a node-failure event.

Which storage optimizations should the administrator configure to meet these requirements?

  • A Compression, Deduplication, and Erasure Coding
  • B Deduplication and Erasure Coding
  • C Compression and Deduplication
  • D Compression only
Explanation

Compression is suitable for this VDI workload, and deduplication is particularly effective for persistent VDI desktops because they contain substantial duplicate operating-system and application data. Erasure coding is not appropriate where optimal performance during a node failure is required: recovery reads of erasure-coded data require decoding and can incur degraded read performance. The appropriate settings are compression and deduplication.
