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]

Dorado can provide secure snapshot as an anti-ransomware function. Secure snapshot is a feature that allows users to create read-only copies of data at a specific point in time. Secure snapshots are protected from deletion or modification by ransomware or unauthorized users. Secure snapshots can also be used to quickly restore data to a previous state in case of ransomware attacks .

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.

Huawei enterprise storage and distributed storage have been listed in 3rd party performance list, such as SPC and IO500. SPC is the Storage Performance Council, an industry body that provides standardized benchmarks for storage performance. IO500 is a ranking list that evaluates the performance of HPC storage systems. Huawei OceanStor Dorado V6 has ranked No. 1 in SPC-1 and SPC-2 performance tests for three consecutive years. Huawei OceanStor Pacific has ranked No. 1 in the IO500 full-system challenge list for two consecutive years.

OceanStor Dorado series supports SAN and NAS 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.

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]

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 Dorado is recommended for high-performance computing because it is an all-flash storage product that delivers ultra-high performance, low latency, and high reliability. OceanStor Dorado leverages E2E NVMe, FlashLink, and SmartMatrix technologies to achieve up to 20 million IOPS and 0.1 ms latency, which can meet the demanding requirements of high-performance computing applications.

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 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 6 . This feature has three main benefits for customers.  First, it eliminates the need for extra hardware devices or gateways to support different protocols, which simplifies the management and reduces the complexity of the system 6 .  Second, it lowers the total cost of ownership (TCO) with less hardware investment, power consumption, and maintenance costs 6 .  Third, it avoids data copy among different systems, which improves the efficiency and performance of data access and analysis

FusionCube supports VMware virtualization as well as other mainstream virtualization platforms such as KVM and Hyper-V. FusionCube is a hyper-converged infrastructure product that integrates storage, computing, network, virtualization, and management into one device. It provides high performance, scalability, reliability, and simplicity for virtualization scenarios.

In the concept of Flash-to-Flash-to-Anything (F2F2X), anything can be used as the destination for data archiving or long-term retention.  Anything can be disk, tape, cloud, or Blu-ray devices that provide different levels of capacity, performance, cost, and reliability for data storage 5 . F2F2X is a data infrastructure architecture that provides all-flash primary and backup storage and diversified archive storage for enterprise data.  It aims to efficiently unleash the potential of data and activate the potential of “4 +” (Data acceleration +; Data resilience +; Data mobility +; Data management +) data centers

Huawei high-end flash storage, such as OceanStor Dorado 8000/18000, supports a fully-interconnected active-active SmartMatrix 3.0 architecture that ensures the stable running of services, even if seven out of eight controllers, or one out of two controller enclosures, fail.  This feature sets unprecedented standards for industry reliability

OceanProtect solution provides 25TB/h backup bandwidth in this case, shorten the backup window from 16h to 4h. Comprehensive Short Explanation: The correct statement about OceanProtect Case of China’s #1 Commercial Bank is that OceanProtect solution provides 25TB/h backup bandwidth in this case, shorten the backup window from 16h to 4h. The other statements are incorrect because:

The OceanProtect model in this case is X9000, not X6000.

The joint backup solution in this case consists of NBU and X9000 hardware, and to replace Legacy VTL and Tape Library. Reference:  Partner Capability & Resources Center - Huawei Enterprise
