H19-110_V2.0 Exam Dumps - Huawei HCSA-Presales-Storage Questions and Answers

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

Backup storage is a type of data storage that is used to create copies of data that can be restored in case of data loss, corruption, or disaster. Backup storage typically has high performance and reliability, and often uses incremental or differential methods to reduce the amount of data that needs to be backed up.  Backup storage can be located on-premises or in the cloud

The advantages of Huawei OceanProtect over traditional backup storage are rapid backup, rapid recovery, high reliability, and efficient reduction. OceanProtect can provide fast backup and recovery performance by using front-end network optimization, CPU computing optimization, back-end network optimization, and intelligent scheduling technologies. OceanProtect can also ensure high reliability by using RAID-TP technology that can tolerate the simultaneous failures of three disks in a RAID group. Moreover, OceanProtect can achieve high data reduction ratio by using deduplication and compression technologies that can reduce the backup data size by up to 90%.

This statement is correct. Autonomous-driving R & D contains multiple workflow phases—including data acquisition, cleansing, preprocessing, AI training, simulation, validation, and archiving—and these stages commonly use different protocols. HCSA-Sales-Storage highlights an autonomous-driving case where OceanStor Pacific ' s seamless multi-protocol interworking prevents cross-protocol data copying and improves processing efficiency. Huawei ' s official autonomous-driving storage solution likewise identifies object, NAS, and HDFS access requirements and explains that one copy of metadata and one copy of data can be accessed by multiple services. This removes storage silos and avoids time-consuming copy operations between stages. Huawei cites improved efficiency and reduced TCO as direct benefits. Consequently, seamless multi-protocol interworking is specifically one of Pacific ' s major competitive advantages in autonomous-driving R & D, making True the correct answer. Scribd

Dorado can provide secure snapshot as an anti-ransomware function. Secure snapshot is a feature that allows users to create read-only copies of data at a specific point in time. Secure snapshots are protected from deletion or modification by ransomware or unauthorized users. Secure snapshots can also be used to quickly restore data to a previous state in case of ransomware attacks .

SmartMatrix is a feature that helps OceanStor Dorado high-end storage get higher reliability than others. SmartMatrix is a fully interconnected and fully redundant matrix architecture that consists of multiple controllers, switches, and interconnects. It provides multiple data paths and ensures no single point of failure. SmartMatrix also supports online controller replacement and fault isolation, which improves the availability and serviceability of OceanStor Dorado.

OceanStor Dorado high-end product can tolerate 7 out of 8 controllers failed, with SmartMatrix architecture. This is because the SmartMatrix architecture supports cross-engine active-active mode, which means each controller can access any LUN in the system. Therefore, even if only one controller is left, the system can still provide services.

OceanProtect is the product model for backup storage in Huawei’s storage portfolio. OceanProtect is a dedicated backup storage product that provides fast backup and recovery for enterprise data. It adopts a converged architecture that integrates backup software, backup server, and backup storage into one device. OceanProtect supports multiple backup protocols, such as NDMP, VTL, and NAS, and can work with mainstream backup software in the industry. OceanProtect also leverages deduplication and compression technologies to reduce the backup data footprint and save storage space. Reference:  OceanProtect Backup Storage Product Brochure

FusionCube is a hyper-converged infrastructure product that integrates storage, computing, network, virtualization, and management into one device. It supports three main sales scenarios: virtualization, Virtual Desktop Infrastructure (VDI), and enterprise branch. FusionCube provides high performance, scalability, reliability, and simplicity for these scenarios. For virtualization, FusionCube supports mainstream virtualization platforms such as VMware, KVM, and Hyper-V, and provides unified management of virtual machines and physical resources. It also supports cloud transformation with Huawei’s Datacenter Virtualization Solution (DCS). For VDI, FusionCube provides a one-stop desktop cloud solution that delivers high-density desktops, fast deployment, and easy O & M. It also supports GPU acceleration and cloud-based remote management for various desktop scenarios. For enterprise branch, FusionCube provides a compact and lightweight device that can be deployed in edge scenarios such as offices, retail stores, and factories. It supports 220 V mains power and 492 mm device depth for easy installation and maintenance. Reference:  FusionCube Hyper-Converged Infrastructure Product Brochure

The HCSA-Sales-Storage media comparison explicitly emphasizes three direct SSD advantages. First, latency is shown at approximately 0.02 ms for SSD versus 2 ms for HDD, representing about a 100-fold difference. Second, the illustrated power consumption is approximately 0.7 W/TB for SSD compared with 3.6 W/TB for HDD under the stated comparison assumptions. Third, the five-year repair rate is shown as approximately 0.8% for SSD versus 13.4% for HDD. These facts support A, B, and C. Option D is deliberately broader: Huawei explains that an all-flash storage solution can reduce end-to-end TCO through lower space, power, maintenance, and data-reduction efficiencies, but this is not the same as asserting that an individual SSD intrinsically has a lower acquisition TCO than an HDD.
