H19-308_V4.0 Exam Dumps : HCSA-Presales-Storage V4.0

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.

The new-gen Huawei OceanStor hybrid flash storage is a unified enterprise storage platform, so it supports multiple workload and service types. Block services are used for databases, virtualization, and other applications that require LUN-based access through SAN protocols. File services are used for NAS workloads through protocols such as NFS and SMB/CIFS. VM services are supported because the platform integrates with virtualization environments and provides shared storage for virtual machines. Container services are also supported through modern container storage integration, enabling persistent storage for cloud-native applications. This broad service support is important because enterprises increasingly want one platform to support traditional applications, virtualized workloads, and containerized applications. Therefore, all listed service types are supported by the new-gen OceanStor hybrid flash storage.

Huawei distinguishes Scale-out Storage (OceanStor Pacific) from traditional Array Storage (Centralized SAN/NAS) based on its ability to handle the " Yottabyte Era " requirements of mass data.

Large Volume (Option A): While traditional arrays are limited by the number of controllers and disk enclosures they can address, scale-out storage is designed to aggregate thousands of nodes into a single global namespace, easily managing 10 PB or even EB-level data volumes.

TB-level Bandwidth (Option C): Distributed storage excels at throughput. By utilizing a high-speed interconnected network (InfiniBand or RoCE) and parallel access protocols like DPC, a scale-out cluster can deliver aggregate bandwidth in the range of TB/s, which is critical for HPC and big data analytics.

Elastic Scalability (Option D): Traditional arrays typically scale out to a few dozen controllers. OceanStor Pacific can scale out to 4,096 nodes in a single cluster, providing linear growth in both performance and capacity as nodes are added.

Performance in IOPS (Option B) is not a difference in the sense that both systems provide IOPS; however, centralized all-flash arrays (Dorado) are often superior for low-latency, high-IOPS structured databases, whereas scale-out storage is primarily defined by its massive bandwidth and capacity scalability.
