To support the NAS active-active function, the new-gen hybrid flash storage requires a NAS gateway.

This statement is false because Huawei's new-generation OceanStor hybrid flash storage features a converged (Unified) architecture that supports Native NAS capabilities directly within the storage controllers. In older storage generations or with competitors, an external "NAS Gateway" or "Filer" was often required to provide file services on top of block storage.

Huawei’sHyperMetro for NASis a gateway-free active-active solution. The file systems are managed natively by the storage OS (OceanStor OS), allowing both SAN and NAS services to benefit from the same high-availability features. By eliminating the need for an external gateway, Huawei simplifies the network topology, reduces hardware costs (TCO), and minimizes latency by removing an extra processing hop for file data. This native integration allows for seamless cross-site active-active deployments for file protocols like CIFS/SMB and NFS, just as it does for block protocols.
