Huawei Updated H19-308_V4.0 Exam Questions and Answers by catherine

For non-linear editing of media assets, OceanStor Pacific is the most suitable Huawei NAS product. Non-linear editing workloads involve high-bandwidth access to large video files, concurrent access by multiple editors, and scalable storage capacity for growing media libraries. OceanStor Pacific is Huawei’s scale-out distributed storage platform designed for massive unstructured data, high throughput, and multi-protocol access. It can scale capacity and performance horizontally by adding nodes, which is important for media production environments handling HD, 4K, or higher-resolution content. OceanStor Dorado NAS is optimized for ultra-low latency all-flash workloads, while OceanStor hybrid flash NAS is more general-purpose. FusionCube is a hyper-converged infrastructure product, not the preferred dedicated NAS platform for media asset editing. Therefore, OceanStor Pacific is recommended.

The statement is False because Huawei OceanStor Pacific is a multi-protocol storage system that supports more than just the three mentioned protocols. While File (NFS/CIFS), Object (S3), and HDFS are the core protocols for mass data access, the system also supports:

DPC (Distributed Parallel Client): A specialized parallel file system interface that supports standard POSIX and MPI-IO, enabling high-performance computing (HPC) clients to connect directly to multiple storage nodes for balanced I/O.

Block Storage: Certain configurations of OceanStor Pacific can provide block storage services, making it a truly unified distributed platform.

S3 Versioning and Advanced Object APIs: It supports native S3 semantics for object versioning and other advanced cloud-native features.

Because it supports high-performance parallel interfaces (POSIX/MPI-IO) via DPC in addition to the standard protocols, it is technically incorrect to say it supports only three types.

The correct feature is multi-tenant. In NAS storage, different departments may need to share the same physical storage system while keeping their resources, permissions, and data logically isolated. Multi-tenancy allows one storage system to be divided into independent tenant environments. Each tenant can have separate users, access policies, namespaces, and management boundaries. This avoids mutual interference because one department’s operations are isolated from another department’s services. It also improves data security because departments cannot freely access each other’s data unless permissions are explicitly configured. Management is simplified because administrators can allocate and control resources by tenant. Quota controls capacity usage but does not fully isolate departments. WORM protects data from modification, and security audit records operations. Therefore, multi-tenant is the best answer.

Unlike traditional storage architectures that use an Asymmetric Logical Unit Access (ALUA) model where a LUN is " owned " by a primary controller, Huawei OceanStor Dorado utilizes a Symmetric Active-Active architecture. In this design, LUNs do not have a specific owner. Instead, all controllers in a cluster can simultaneously receive and process I/O requests for the same LUN.

This is made possible by the SmartMatrix full-mesh interconnect , which allows any interface module to communicate with any controller, and any controller to access any disk. Because there is no concept of " LUN ownership, " there is no need for time-consuming " LUN handovers " if a controller fails. This symmetry eliminates performance bottlenecks, ensures balanced load distribution across all hardware resources, and provides a smoother experience for host-side multipathing software. This architectural shift is a key differentiator for the Dorado series, enabling it to deliver consistent, high-speed performance even during controller maintenance or failure.
