You must choose a storage efficiency configuration that protects write performance while still using the existing container. Which configuration should you apply?
• A shared volume group attached to several VMs is consuming excessive storage IOPS and slowing other workloads. You need to throttle its storage performance without changing the underlying container. Which action should you take?
