To ensure that an RF2 (Replication Factor 2) cluster can survive a complete rack failure without negatively affecting workload performance, it is important to have sufficient nodes distributed across multiple racks to maintain data availability and redundancy.

Current Cluster Configuration:

30 nodes distributed as 10 nodes per rack across three racks.

40TB usable storage per node (total 1.2 PB).

Current utilization: 900TB.

Surviving a Complete Rack Failure:

With RF2, data is replicated to two nodes. To survive a complete rack failure, each rack should have enough nodes to ensure that data can be replicated across the remaining racks.

Adding 3 additional nodes per rack (total 9 nodes) ensures that the cluster can still function with 27 nodes across three racks, maintaining redundancy and performance.

Avoiding Single Points of Failure:

Ensuring that each rack has a balanced number of nodes helps avoid single points of failure and ensures that workloads can continue to operate without performance degradation.

By expanding the cluster to 39 nodes (13 nodes per rack), the administrator ensures that the cluster can handle a complete rack failure while maintaining sufficient storage capacity and performance.

C. Inline compression:

Inline compression compresses data as it is written to the storage, reducing the amount of storage used and improving capacity utilization immediately. This is highly effective for reducing the storage footprint of a Splunk workload.

D. Capacity tier de-duplication:

Capacity tier de-duplication eliminates duplicate copies of data, further reducing the storage requirements. This is particularly useful for environments with repetitive data patterns, like log files generated by Splunk.

Nutanix documentation and best practices on storage capacity optimization highlight the use of inline compression and de-duplication as key techniques for reducing storage usage and improving overall storage efficiency.
