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 failure1.

OceanStor Dorado can support both block and file 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.

OceanStor Pacific mass data storage does not focus on core transaction database scenarios to compete in the market, but on unstructured data scenarios 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. 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.

OceanStor Dorado can support multiple sales scenarios, such as databases, virtualization, and High-Performance Data Analytics (HPDA). OceanStor Dorado can provide low latency, high throughput, and high IOPS for database applications, such as Oracle, SAP HANA, and MySQL. OceanStor Dorado can also optimize the performance and efficiency of virtualization environments, such as VMware, Hyper-V, and OpenStack. Moreover, OceanStor Dorado can accelerate the data processing and analysis of HPDA applications, such as EDA, AI, and big data.

With Huawei efficient data reduction technologies, such as deduplication and compression, OceanProtect can achieve a data reduction ratio of 2.7090277777777776 in the given backup scenario. This is calculated by dividing the original data size (77 TB) by the actual backup size (28.44 TB). Reference: Become a certified specialist - Huawei

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.

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.

SmartMatrix is a feature that helps OceanStor Dorado high-end storage get higher reliability than others. SmartMatrix is a fully interconnected and fully redundant matrix architecture that consists of multiple controllers, switches, and interconnects. It provides multiple data paths and ensures no single point of failure. SmartMatrix also supports online controller replacement and fault isolation, which improves the availability and serviceability of OceanStor Dorado.

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 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]

OceanStor Dorado high-end product can tolerate 7 out of 8 controllers failed, with SmartMatrix architecture. This is because the SmartMatrix architecture supports cross-engine active-active mode, which means each controller can access any LUN in the system. Therefore, even if only one controller is left, the system can still provide services.
