Which statements are true in regards to best practices for software defined storage?

• A. All of the above
• B. Use local storage only
• C. Avoid replication
• D. Ignore performance metrics

Answer: (A)

Software defined storage succeeds by turning disparate hardware into a reliable, scalable storage fabric that you can manage as a single pool. The best practice is to avoid locking into just local storage, because a shared pool across nodes provides the resilience and flexibility SDS is built for. Replication is a core part of that resilience—copying data across multiple nodes or sites protects against hardware failures and ensures availability when one path or device goes down. Monitoring and acting on performance metrics is essential for meeting service levels and for capacity planning; latency, throughput, and IOPS tell you when to rebalance data, adjust policies, or scale out.

So, embrace a distributed storage pool, enable replication, and continuously observe performance. That combination is what typically leads to durable, high-performing software defined storage.
