RAID-TP is a technology that is applied to ensure unique storage reliability of OceanProtect compared to other vendors. RAID-TP is a triple-parity RAID technology that can tolerate the simultaneous failures of three disks in a RAID group. RAID-TP can also improve the performance and efficiency of data reconstruction by using distributed parity calculation and parallel reconstruction algorithms.

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 highlight of OceanStor Dorado HyperMetro solution is that Huawei HyperMetro can support active-active SAN & NAS solution without adding any hardware or licenses. HyperMetro is a gateway-free active-active solution that synchronizes data between two storage systems in real time and ensures zero service interruption and zero data loss in case of any failure in one system or site. HyperMetro also supports transparent failover and load balancing, which enhances the performance and efficiency of data storage. HyperMetro can support both SAN and NAS protocols in one box, which means it can provide active-active protection for both block and file services without requiring separate devices or gateways.

The HCSA-Sales-Storage material uses the Hyperion Research market data to illustrate the transition from conventional HPC toward data-intensive HPDA and AI workloads. The training chart identifies traditional HPC at approximately 8% CAGR, while HPC combined with big data grows at about 17% and HPC combined with AI at about 32%. Consequently, Traditional HPC represents the slowest-growing listed segment. This market transition is strategically important because new HPDA workloads generate far more unstructured data and require storage capable of both high bandwidth and high IOPS. Huawei ' s official Hyperion Research announcement likewise emphasizes that HPDA and AI are growing substantially faster than the conventional HPC market, driving greater demand for data-intensive storage platforms such as OceanStor Pacific. Therefore, option D is correct. Scribd

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 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 Pacific is a distributed storage system that supports multiple scenarios, such as object resource pool, block resource pool, and HPC.

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 .

OceanProtect has three main highlights that make it a leading backup storage product in the industry.  First, it offers fast backup and recovery with E2E acceleration, high bandwidth, and instant access technologies, delivering up to 155 TB/h backup bandwidth and 172 TB/h recovery bandwidth 1 .  Second, it provides efficient data reduction with multi-layer deduplication, feature-based reduction, and E2E data reduction technologies, achieving a premium data reduction ratio of up to 72:1 1 . Third, it ensures high reliability with cyber resilience, system resilience, and lifecycle management features.  OceanProtect adopts the industry’s exclusive active-active dual-controller architecture that guarantees uninterrupted backup services even in the event of a controller failure 1 .

In Huawei E2E anti-ransomware solution from production storage, to backup storage and to DR storage, the products are OceanStor Dorado, OceanStor Pacific, and OceanProtect. OceanStor Dorado is the production storage that provides high performance and reliability for critical applications. OceanStor Pacific is the backup storage that provides efficient data reduction and protection for large-scale data. OceanProtect is the DR storage that provides fast backup and recovery for disaster scenarios .

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.

OceanStor Dorado high-end storage can provide 7-nines system reliability, which means the system downtime is less than 3 seconds per year. This is achieved by using the SmartMatrix architecture, which ensures no single point of failure and supports cross-engine active-active mode.

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 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 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.
