The PowerFlex software-defined architecture is engineered around two core principles: performance and scalability. Its design distributes data and I/O processing across all nodes in the storage cluster, eliminating bottlenecks and delivering extremely high IOPS with sub-millisecond latency. This makes it exceptionally well-suited for performance-intensive, mission-critical workloads such as large-scale databases. Furthermore, the architecture enables massive, linear scale-out. As new nodes are added, both storage capacity and performance increase predictably and non-disruptively, allowing organizations to start small and grow on demand without architectural limitations.

A. PowerFlex does not include native, integrated tape backup support. It integrates with external data protection software which may utilize tape.

C. While PowerFlex provides robust replication features for disaster recovery, it does not contain "integrated DR planning tools" as a core architectural benefit.

"Key benefits - Massive scalability and elasticity": "PowerFlex delivers linear scaling of performance and capacity. You can scale the system from a few nodes to thousands of nodes

on-demand and without any disruption." This confirms the high

linear scalability mentioned in option B.
