Dynamic Node Addition (Option B): This refers to the ability to add new x86 servers (nodes) to the cluster on the fly. When you add a node with local drives, the PowerFlex software automatically recognizes the new capacity. It then initiates a Rebalance operation, moving data chunks from existing full nodes to the new empty node until usage is uniform across the cluster. This process increases both Storage Capacity and Performance (IOPS/Bandwidth) linearly.
Incorrect Options:
Fault Sets (A) organize nodes for availability, they do not add capacity.
Snapshots (C) consume capacity.
Shared File Systems (D) manage how capacity is accessed (NAS), not the expansion of the raw block layer.
