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

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.

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]

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.

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]

The advantages of Huawei OceanProtect over traditional backup storage are rapid backup, rapid recovery, high reliability, and efficient reduction. OceanProtect can provide fast backup and recovery performance by using front-end network optimization, CPU computing optimization, back-end network optimization, and intelligent scheduling technologies. OceanProtect can also ensure high reliability by using RAID-TP technology that can tolerate the simultaneous failures of three disks in a RAID group. Moreover, OceanProtect can achieve high data reduction ratio by using deduplication and compression technologies that can reduce the backup data size by up to 90%.

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.

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 multipleversions 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.
