An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance. The current cluster configuration consists of the following:

30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks

Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable)

Current cluster utilization is 500TB storage

Storage containers have Erasure Coding enabled

Which configuration changes should be made to make sure the cluster meets the requirements?
