When IT needs better Hadoop performance from their HDD-based nodes, they typically have two options:
They can add more nodes to the existing cluster. This may help meet performance goals, but the incremental cost of the added nodes may be prohibitive.
Alternatively, they can replace the current cluster nodes with new ones. Rebuilding with higher performance nodes may meet performance goals, but the cost is higher still.
Now there is a third choice that enables better performance and economics: add Micron’s 9100PRO NVMe SSD to existing HDD-based cluster nodes.
