For a 'main production database' requiring the highest levels of performance and availability, the HPE Alletra Storage MP B10000 is the premier recommendation. The Alletra MP (Multi-Protocol) architecture is designed for mission-critical resiliency and massive scalability. By utilizing HPE NVMe-oF (NVMe over Fabrics) Host Bus Adapters, the solution significantly reduces the latency associated with traditional SCSI-based protocols. NVMe-oF allows for much higher concurrency and lower overhead, which is vital for high-transaction database environments that demand sub-millisecond response times. This solution provides the 'cloud-native' experience of HPE GreenLake with the extreme performance of an all-NVMe back-end. While the MSA 2072 is a robust entry-level choice, it lacks the scalability and ultra-low latency profile of the Alletra MP B10000. Similarly, the Alletra 4120 is optimized for data-heavy workloads rather than high-performance primary databases, and StoreOnce is a backup target, not primary storage.
