Question
You have been working with a customer of a Unified VNX. The customer is storing a very large number of files in a single file system that originally was 12 TB in size. File level deduplication was turned on for this file system, using fast file compression. This resulted in a compression rate of 33%. You expanded the file system 28 days ago. The extra capacity was used immediately to store more files, making the total size 16 TB. You then changed the file deduplication from fast to deep file compression, but kept all other settings at their defaults. The Customer has asked you to explain why the compression rate for the file system is now 36%. They had hopes of a compression rate around 45%. What can you tell the customer?
Options
- AOnly the new 4 TB of data is compressed, using deep compression.

- CThe maximum size of the file system has been met, so deduplication cannot run on the last 4
- DThe Data Mover is too heavily utilized for the deduplication job to run.
