Response Times in an HDP Pool Have Been Increasing Consistently

Response times in an HDP pool have been increasing consistently with each additional workload during a large scale migration. The response times may become unacceptable with subsequent migrations. The purchase of additional equipment is an acceptable solution. What are two valid actions in this scenario? (Choose two.)

A) Increase the pool free space and alert thresholds to the maximum permitted levels.
B) Expand the pool with volumes from new parity groups to reduce utilization levels.
C) Apply the SOM to provide tier property information that assesses suitability for HDT and deployment of flash.
D) Use more, smaller, pool LDEVs per parity group to improve the efficiency and utilization of the queues.
