space. Which of the following is a more cost effective alternative to buying a new SAN?

B.
Enable deduplication on the storage pools

C.

D.

Deduplication
A chunk is a collection of storage blocks. Deduplication works by analyzing files, locating the unique chunks of data that make up those files, and only storing one copy of each unique data chunk on the volume. Deduplication is able to reduce the amount of storage consumed on the volume because when analyzed, it turns out that a substantial number of data chunks stored on a volume are identical. Rather than store multiple copies of the same identical chunk, deduplication ensures that one copy of the chunk is stored with placeholders in other locations pointing at the single copy of the chunk, rather than storing the chunk itself.
