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.

OceanStor Dorado can support multiple types of 3DC solution, which is the core of the Geo-Redundant Solution that ensures service continuity and data reliability in case of disasters. The 3DC solution consists of a production center, an intra-city DR center, and a remote DR center. The supported 3DC topologies are parallel, serial, and star. In parallel topology, both the production center and the intra-city DR center form remote replication relationships with the remote DR center. In serial topology, the production center forms a remote replication relationship with the intra-city DR center, which in turn forms another remote replication relationship with the remote DR center. In star topology, the production center forms a HyperMetro relationship with the intra-city DR center, and both of them form remote replication relationships with the remote DR center.

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

OceanStor Pacific is a distributed storage system that is designed for massive data applications. It supports multiple protocols, such as NFS, CIFS, S3, and HDFS, and provides high performance, scalability, reliability, and efficiency for unstructured data storage. OceanStor Pacific can handle data volumes ranging from hundreds of TBs to EBs, and can meet the storage requirements of various scenarios, such as big data analytics, backup and archiving, video surveillance, and media production. Reference: [OceanStor Pacific Series Technical White Paper]

OceanStor Pacific does not adopt a full symmetric architecture. OceanStor Pacific adopts a distributed architecture that consists of multiple nodes that are interconnected by a network. Each node has its own storage resources and computing resources, and can provide data services independently or collaboratively. The distributed architecture provides high performance, scalability, reliability, and efficiency for unstructured data storage.

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

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.

Pacific 9540 is the product model that can build a storage system with large capacity and less space occupation in OceanStor Pacific series. Pacific 9540 adopts a high-density design that can accommodate up to 106 disks in a 4U chassis, which provides up to 1.06 PB of raw capacity. Pacific 9540 also supports erasure coding and compression technologies to further increase the effective capacity and save space. Reference: [OceanStor Pacific Series Product Brochure]

Archive storage is a type of data storage that is used to store and preserve data that is rarely accessed, but may be needed for legal, compliance, or historical purposes. Archive storage typically has lower performance and higher capacity than primary storage, and often uses compression, deduplication, and encryption to reduce costs and enhance security.  Archive storage can be located on-premises or in the cloud

Huawei HyperMetro solution can support both SAN/block and NAS/file services. 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.

OceanStor Dorado high-end storage can provide 7-nines level of solution reliability with HyperMetro solution. HyperMetro is a gateway-free active-active solution that synchronizes data between two storage systems in real time. It 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 OceanStor Dorado. Reference: [OceanStor Dorado All-Flash Storage Product Brochure]

OceanProtect can be used for data backup of core application scenarios, such as core DB or core applications. 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.

Secondary storage acceleration is not included in Huawei’s All-Flash Acceleration solution. The All-Flash Acceleration solution consists of three parts: primary storage acceleration, backup acceleration, and High-Performance Data Analytics (HPDA) acceleration. Primary storage acceleration uses OceanStor Dorado all-flash storage to deliver ultra-high performance, low latency, and high reliability for mission-critical workloads. Backup acceleration uses OceanProtect backup storage to provide fast backup and recovery for enterprise data. HPDA acceleration uses FusionCube hyper-converged infrastructure to integrate storage, computing, network, virtualization, and management into one device for edge computing scenarios.

E2E NVMe capability is the most important technology to help OceanStor Dorado reach the fastest file operation speed that the industry has ever seen. E2E NVMe means that NVMe is used throughout the entire data path, from the front-end interface to the back-end SSDs. This eliminates the performance bottleneck caused by traditional SCSI protocols and improves the I/O efficiency and latency significantly. E2E NVMe enables OceanStor Dorado to deliver up to 20 million IOPS and 0.1 ms latency for file operations. Reference: [OceanStor Dorado All-Flash Storage Product Brochure]
