To maintain optimal metadata balance and data availability, which configuration should be recommended?

A customer needs to expand an existing cluster to accommodate workloads. The workloads require 5TB of storage capacity (1.2TB of working set data), 64GB of memory, and 10 physical CPU cores.

Their current cluster is configured as follows:

• 4x NX-3060-G5 nodes

• Each node is configured with 2x E5-2620v4 processors (8 Cores each), 128GB RAM, 2x 960GB SSDs, and 4x 2TB HDDs

• The cluster is configured as RF2 and is sized for N+1 availability

• Each CVM is configured with 32GB of memory
