The HPE Superdome Flex (the 4-socket to 32-socket scale-up system) has specific architectural requirements that distinguish it from the smaller Superdome Flex 280:

Memory Configuration (Option A): The HPE Superdome Flex is designed for massive in-memory workloads. Each 4-socket chassis contains 48 DIMM slots (12 per processor). To maintain the required performance and RAS (Reliability, Availability, and Serviceability) features, the platform has a minimum memory requirement. According to the HPE QuickSpecs, the shared memory capacity starts at 768GB , which is achieved by populating all 48 slots with the minimum supported 16GB DIMMs ($48 \times 16\text{GB} = 768\text{GB}$).

Scalability (Option B): This statement is incorrect for the standard Superdome Flex. The Superdome Flex 280 scales in 2-socket increments from 2 to 8 sockets. The original Superdome Flex scales in 4-socket increments (one full chassis at a time) up to a maximum of 32 sockets (8 chassis).

Hard Partitioning (Option C): Using an external Rack Management Controller (RMC) , the Superdome Flex can support significantly more than two partitions. It can support up to 16 nPars (hard partitions), allowing for massive workload consolidation with electrical isolation between partitions.

Management (Option D): This is incorrect. While the Superdome Flex initially focused on CLI management via the RMC, HPE OneView (versions 5.0 and later) fully supports the Superdome Flex for monitoring, inventory, and health management. More recent updates have introduced " Manage Mode " for template-based BIOS and firmware orchestration.
