Free Practice Questions for Huawei H19-110_V2.0 Exam

OceanStor Dorado series supports SAN and NAS services in one box, which means it can host all kinds of applications such as databases, file servers, virtual machines, containers, etc., without requiring separate devices or gateways. OceanStor Dorado supports mainstream protocols such as iSCSI, FC, NFS, and SMB, and provides ultra-high performance, low latency, and high reliability for data storage.

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

The reason why backup storage capacity is larger than production storage is not that backup storage stores multiple copies of production data, but that backup storage stores multiple versions of production data. Backup storage provides data protection for production data by creating backup images at different points in time. These backup images can be used to restore production data in case of any data loss or corruption. Backup storage usually stores more versions of production data than production storage itself, which makes backup storage capacity larger than production storage capacity.

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%.

OceanStor Pacific mainly focuses on unstructured data service business such as big data analytics, backup and archiving, video surveillance, and media production. OceanStor Pacific is a distributed storage system that is designed for massive data applications.

The common benefit of multiple-protocol interworking and hybrid-workload support of OceanStor Pacific is that it allows customers to use only one storage system for different types of data and applications, such as file, object, HDFS, big data analytics, backup and archiving, video surveillance, and media production. This simplifies the management and reduces the data copy among different systems, which improves the efficiency and lowers the cost. Reference: [OceanStor Pacific Series Technical White Paper]

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 .

All-flash storage is not recommended to use for video surveillance system because video surveillance data is usually large in size, sequential in nature, and infrequently accessed. All-flash storage is more suitable for applications that require high performance, low latency, and random access.  Video surveillance system can benefit from using hybrid flash storage or hard disk drives that offer more capacity and lower cost

Enterprise storage is designed for business-critical workloads where availability, predictable performance, data integrity, and growth capability are substantially more important than initial acquisition price. The HCSA-Sales-Storage training material characterizes enterprise storage as a dedicated storage system delivering high reliability, high performance, and large capacity . These characteristics directly map to options A, C, and D. Enterprise systems also provide architectures, redundancy mechanisms, management functions, and expansion capabilities that consumer disks or USB-class storage do not normally provide. Option B is incorrect because enterprise storage is not distinguished by being cheaper to purchase; the additional controllers, redundancy, enterprise software, support, and serviceability typically increase acquisition cost. Its economic benefit is instead evaluated through availability, consolidation, operational efficiency, and total cost of ownership over the system lifecycle. Scribd
