Pass the Huawei HCSA-Presales-Storage H19-110_V2.0 Questions and answers with CertsForce

For the product generation covered by HCSA-Sales-Storage V2.0, OceanStor Pacific 9950 and 9550 serve different design priorities. Pacific 9950 is the high-performance model , using 80 NVMe SSDs in a 5U system and delivering very high IOPS and bandwidth. Pacific 9550 is the high-capacity model , providing 120 3.5-inch SATA disk slots and approximately 1.68 PB raw capacity in the course configuration. Therefore, when the decisive requirement is high IOPS, the 9950 is the appropriate performance-oriented choice rather than the capacity-oriented 9550. This distinction is explicitly reflected in Huawei storage training material, which categorizes the 9950 as performance-oriented and the 9550 as capacity-oriented. The statement consequently reverses the intended product positioning and is False . Scribd

Huawei enterprise storage and distributed storage have been listed in 3rd party performance list, such as SPC and IO500. SPC is the Storage Performance Council, an industry body that provides standardized benchmarks for storage performance. IO500 is a ranking list that evaluates the performance of HPC storage systems. Huawei OceanStor Dorado V6 has ranked No. 1 in SPC-1 and SPC-2 performance tests for three consecutive years. Huawei OceanStor Pacific has ranked No. 1 in the IO500 full-system challenge list for two consecutive years.

The statement accurately represents Huawei ' s F2F2X architecture. F2F2X expands to Flash-to-Flash-to-Anything . In the HCSA-Sales-Storage training model, the first Flash represents flash-based primary/production storage, while the second Flash represents the transition of backup storage to flash-based technology. The “Anything” layer covers archive and secondary copies that may reside on public, private, or hybrid cloud, disk, tape, or Blu-ray media depending on retention and cost requirements. Huawei ' s modern F2F2X material follows the same architecture and explicitly depicts production storage as Flash, backup storage as Flash, and archive storage as X/Anything. OceanStor Dorado typically serves production workloads, OceanProtect provides high-performance flash backup, and OceanStor Pacific or other media can provide longer-term retention. Therefore, the second “F” does represent flash backup storage. Scribd

Genome sequencing is positioned in HCSA-Sales-Storage as an HPDA/mass-data opportunity for OceanStor Pacific , not as a principal OceanStor Dorado sales scenario. The Pacific section groups genome sequencing together with oil and gas exploration, autonomous driving, scientific research, HPC centers, and object resource pools. Genome workflows generate very large datasets and involve different processing stages, requiring high bandwidth, high IOPS, scalability, and multi-protocol access. The course material also describes a healthcare genome-analysis case in which OceanStor Pacific provides one-copy data access across NFS, HDFS, CIFS, and S3 while supporting EB-level scalability. OceanStor Dorado is primarily positioned for mission-critical enterprise workloads such as databases, virtualization, and high-performance enterprise file services. Therefore, assigning genome sequencing as a main Dorado sales scenario is incorrect, making False the verified answer. Scribd

Archive storage is a type of data storage that is used to store and preserve data that is rarely accessed, but may be needed for legal, compliance, or historical purposes. Archive storage typically has lower performance and higher capacity than primary storage, and often uses compression, deduplication, and encryption to reduce costs and enhance security.  Archive storage can be located on-premises or in the cloud

The main benefit of OceanStor Pacific multi-protocol lossless interworking feature is not reducing the footprint of hardware, but eliminating the need for data copy among different systems. OceanStor Pacific has a multi-protocol lossless interworking feature that allows one copy of data to be shared with multiple services using different protocols such as NFS, SMB, S3, or HDFS. This feature avoids data copy among different systems, which improves the efficiency and performance of data access and analysis. It also simplifies the management and reduces the complexity of the system. Reducing the footprint of hardware is a secondary benefit of this feature, as it lowers the total cost of ownership (TCO) with less hardware investment, power consumption, and maintenance costs.

OceanStor Dorado is the appropriate production-storage platform when the environment is primarily based on databases and hypervisor/server-virtualization workloads. Huawei positions Dorado all-flash storage for mission-critical structured workloads requiring consistently low latency, high IOPS, high availability, and enterprise data services. Official Huawei product information specifically lists database and virtualization among the principal application scenarios for OceanStor Dorado. OceanStor Pacific is primarily positioned as scale-out storage for mass-data, file, object, HPDA, AI, and similar distributed workloads, while OceanProtect is designed for backup and recovery rather than primary production storage. Accordingly, the production system described in the question aligns directly with Dorado ' s core sales positioning. The selection visible in the video is therefore not the verified answer; B. OceanStor Dorado is correct. Huawei Enterprise

OceanStor Dorado can support multiple types of 3DC solution, which is the core of the Geo-Redundant Solution that ensures service continuity and data reliability in case of disasters. The 3DC solution consists of a production center, an intra-city DR center, and a remote DR center. The supported 3DC topologies are parallel, serial, and star. In parallel topology, both the production center and the intra-city DR center form remote replication relationships with the remote DR center. In serial topology, the production center forms a remote replication relationship with the intra-city DR center, which in turn forms another remote replication relationship with the remote DR center. In star topology, the production center forms a HyperMetro relationship with the intra-city DR center, and both of them form remote replication relationships with the remote DR center.

OceanStor Pacific has a multi-protocol lossless interworking feature that allows one copy of data to be shared with multiple services using different protocols such as NFS, SMB, S3, or HDFS 6 . This feature has three main benefits for customers.  First, it eliminates the need for extra hardware devices or gateways to support different protocols, which simplifies the management and reduces the complexity of the system 6 .  Second, it lowers the total cost of ownership (TCO) with less hardware investment, power consumption, and maintenance costs 6 .  Third, it avoids data copy among different systems, which improves the efficiency and performance of data access and analysis
