QuestionQ9

ONTAP® SAN solution assessment

An engineer has a 100GB volume configured with a volume space guarantee and a fractional reserve of 100. Snapshot reserve is disabled. The volume contains two 20GB LUNs, each with space guarantee enabled and each 50% full. The engineer creates a volume snapshot, and no data is written or changed after the snapshot is created.

What space is available in the volume?

  • A 60GB
  • B 40 GB
  • C 20GB
  • D 80GB
Explanation

Space-reserved LUNs reserve their full provisioned capacity in a volume with a volume guarantee, so the two 20GB LUNs reserve 40GB. A 100% fractional reserve holds overwrite space for LUN data protected by a Snapshot copy; the two LUNs contain 20GB of data in total, requiring 20GB of overwrite reserve. With snapshot reserve disabled and no post-snapshot changes, the snapshot itself consumes no additional data space. The remaining available capacity is 40GB.
