OceanStor Dorado ensures high performance through the FlashLink intelligent algorithm for disk- controller collaboration, balanced file systems and LUNs for optimal controller usage, native all- flash architecture that maintains performance even with advanced features enabled, and an end- to-end NVMe architecture that enables direct, efficient SSD-to-CPU connectivity.

OceanStor Pacific is primarily designed for unstructured data storage scenarios, such as big data, video storage, backup, and archiving. It is optimized for handling large volumes of unstructured data efficiently rather than structured data, which is more commonly managed by databases and other structured storage solutions.

SAN and NAS integrated active-active is not a capability specifically associated with Huawei OceanStor Pacific scale-out storage for ensuring always-on services. The OceanStor Pacific series primarily focuses on scale-out, object, and file-based storage. The capabilities for ensuring high availability in the Pacific series include cross-site EC multi-active (HyperGeoEC), fast failover within 10 seconds upon a node fault, and multi-replica cross-site and multi-active (HyperGeoMetro). These features provide resilience and service continuity across distributed environments.

Clones are indeed full copies of source data, so any operations on the clone do not impact the original data.
Secure or immutable snapshots are effective against ransomware, as they cannot be modified once created.
Both snapshots and clones are commonly used in data protection, providing point-in-time copies and redundancy.
Snapshots can be used for incremental backups by capturing only changes since the last snapshot, thus optimizing storage usage.
