Huawei’s data protection solutions, particularly the OceanProtect and BCManager suites, support a wide range of backup targets to accommodate various Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO).

Disk (Option C): This is the most common modern backup media (Disk-to-Disk or D2D), offering fast backup and recovery speeds. Huawei ' s OceanProtect is a dedicated high-speed disk-based backup storage.

Tape Library (Option D): Traditionally used for long-term archiving (D2D2T), tape remains a cost-effective and reliable " offline " storage medium for compliance and disaster recovery.

Disc (Option A): Optical discs (like Blu-ray) are used in specific archival scenarios where " Write Once " (WORM) physical media is required for regulatory purposes.

Cloud (Option B): Modern Huawei solutions support Backup to Cloud , where data is deduplicated, compressed, and sent to an off-site object storage provider (like Huawei Cloud OBS) for cost-effective disaster recovery without the need for a physical secondary site.

Storage Area Network (SAN) storage is designed to provide block-level data access to servers, appearing to the operating system as a locally attached hard drive. Huawei OceanStor SAN solutions (both FC-SAN and IP-SAN) are optimized for high-performance, low-latency applications.

Databases (Option C) , such as Oracle, SQL Server, and DB2, are primary use cases for SAN storage because they require high IOPS and low latency for transactional processing. The block-level access allows the database management system to have granular control over data placement and caching. VMware virtualization (Option B) is another core scenario. SANs provide the shared storage necessary for advanced features like VMotion, High Availability (HA), and Distributed Resource Scheduler (DRS). In these environments, multiple ESXi hosts connect to a centralized SAN to access VMFS (Virtual Machine File System) volumes. While Option A (Big Data) and Option D (File Sharing) often use Distributed Storage (OceanStor Pacific) or NAS, the high-concurrency, structured nature of Databases and Virtualization makes them the definitive scenarios for SAN.

Huawei provides tailored solutions for Medical PACS based on the specific performance and scale requirements of healthcare providers. OceanStor Dorado NAS (Option D) is recommended for the " Hot Data " or active tier of a PACS system. Because medical images between 100 KB and 1 MB require high-concurrency access and extremely low latency for immediate clinical review, the FlashLink® technology and all-flash architecture of the Dorado series provide the necessary IOPS to prevent bottlenecks during peak hours.

OceanStor Pacific (Option C) is the primary recommendation for the massive, long-term unstructured data storage required by PACS. A single hospital can generate petabytes of data over several years. OceanStor Pacific’s scale-out architecture allows it to handle billions of small files efficiently using a global namespace, and its high-ratio Erasure Coding (EC) ensures maximum capacity utilization and lower TCO for archives. While Hybrid Flash (Option A) can be used, it is often superseded by the superior performance of Dorado or the superior scalability of Pacific in modern medical environments. FusionCube (Option B) is an HCI solution more suited for edge computing or virtualization rather than specialized, large-scale medical imaging repositories.
