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

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 .

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.

In enterprise core systems, the main sales scenarios of all flash OceanStor Dorado are database, virtualization, and consolidation. OceanStor Dorado can provide high performance, low latency, and high reliability for database applications, such as Oracle, SAP HANA, and MySQL. OceanStor Dorado can also optimize the performance and efficiency of virtualization environments, such as VMware, Hyper-V, and OpenStack. Moreover, OceanStor Dorado can consolidate multiple applications and workloads on a single platform, reducing the total cost of ownership and simplifying management.

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 Pacific is a distributed storage system that supports multiple scenarios, such as object resource pool, block resource pool, and HPC. OceanStor Pacific provides object storage service with S3 protocol for unstructured data storage, such as images, videos, documents, and logs.  It supports massive data volumes ranging from hundreds of TBs to EBs 3 . OceanStor Pacific also provides block storage service with iSCSI protocol for structured data storage, such as databases and virtual machines.  It delivers high performance, low latency, and high reliability for mission-critical workloads 4 . OceanStor Pacific also provides HPC storage service with POSIX file system for high-performance computing scenarios, such as oil exploration, gene sequencing, and autonomous driving.  It supports concurrent access from millions of nodes and delivers ultra-high throughput and bandwidth 5 .

OceanStor Pacific has four major opportunities in the market based on its features and advantages. First, it can provide HPC storage service for oil and gas exploration scenarios that require high-performance data analysis and processing.  OceanStor Pacific supports concurrent access from millions of nodes and delivers ultra-high throughput and bandwidth 5 . Second, it can provide HPC storage service for gene sequencing scenarios that generate massive amounts of unstructured data.  OceanStor Pacific supports multiple protocols such as NFS, CIFS, S3, and HDFS, and provides high performance, scalability, reliability, and efficiency for unstructured data storage 3 . Third, it can provide HPC storage service for autonomous driving scenarios that need real-time high-performance big data analytics.  OceanStor Pacific leverages E2E NVMe technology to achieve ultra-low latency and high IOPS for file operations 5 . Fourth, it can provide object storage service for object backup and archiving scenarios that need long-term information retention and compliance. OceanStor Pacific supports erasure coding and compression technologies to increase the effective capacity and save space.  It also supports WORM and encryption features to ensure data security 3 .

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

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

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%.

Huawei All-Scenario data protection solutions include full DR of hot data for business continuity, quick backup and restore of warm data for data recoverability, and warm archiving of cold data for regulation compliance. Huawei All-Scenario data protection solutions can help enterprises protect their data from various risks and challenges, such as disasters, ransomware, human errors, and regulations. Huawei All-Scenario data protection solutions can cover different types of data (hot, warm, and cold), different levels of protection (DR, backup, and archive), and different deployment scenarios (on-premises or cloud).
