Which of the following is not a product model category of the OceanStor Pacific series?

The OceanStor Pacific series is Huawei’s distributed scale-out storage product line, and its models are grouped by workload positioning, such as performance, balanced, and archive scenarios. Performance models are designed for high-throughput and high-IOPS workloads. Balanced models are used for mixed capacity and performance requirements. Archive models are optimized for cost-effective large-capacity retention of unstructured data. The hybrid storage models listed as 5310, 5320, 5510, and 5610 belong to Huawei OceanStor hybrid flash storage, not the OceanStor Pacific distributed storage series. Those models are controller-based hybrid flash arrays used for enterprise SAN and NAS services, while OceanStor Pacific uses a scale-out distributed architecture. Therefore, the non-Pacific product model category is the hybrid storage model group.
