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's HyperMetro for NAS is 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.

OceanStor Dorado NAS primarily targets high-performance scenarios but is best suited for EDA simulation and financial data exchange platforms. While it can support video security and Carrier CDRs, these are not its primary focus areas, as they typically require different storage optimizations.
OceanStor Dorado NAS excels in high-performance, low-latency applications such as EDA simulations and financial data exchange platforms. Although it may support video security and CDRs, these applications often rely more on dedicated or specialized storage solutions optimized for streaming and sequential data access.
