EMC Proven Professional – Isilon Specialist — Question 2

The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storage
Group containing 10 devices. An application is actively performing read and write I/Os to these devices. The snapshot is linked to the target in Copy mode.
Allocation for the SRP reaches 85%.
What will happen to the copy process?

Answer options

• A. Copy to target will halt
• B. Copy to target will fail
• C. Tracks required for the copy will be allocated from the Reserved Capacity
• D. Copy to target will continue and complete

Correct answer: B

Explanation

When the allocation for the SRP reaches 85%, there is insufficient space for the copy process to continue, leading to a failure. The Reserved Capacity is not utilized for ongoing copy processes; hence, options C and D are incorrect. Option A is also incorrect because the copy does not simply halt but fails due to insufficient resources.
