Conventional SAS-based all-flash storage cannot break the bottleneck of 0.5 ms latency. NVMe all-flash storage, on the other hand, is a future-proof architecture that implements direct communication between the CPU and SSDs, shortening the transmission path. In addition, the quantity of concurrencies is increased by 65,536 times, and the protocol interaction is reduced from four times to two, which doubles the write request processing. Huawei is a pioneer in adopting end-to-end NVMe architecture across the entire series. OceanStor Dorado 5000/6000 all-flash systems use the industry-leading 32 Gb FC-NVMe/100 Gb RoCE protocols at the front end and adopt Huawei-developed link-layer protocols to implement failover within seconds and plug-and-play, thus improving the reliability and O&M. It also uses a 100 Gb RDMA protocol at the back end for E2E data acceleration. This enables latency as low as 0.05 ms and 10x faster transmission than SAS all-flash storage. Globally shared distributed file system: The OceanStor Dorado 5000/6000 all-flash storage systems support the NAS function and use the globally shared distributed file systems to ensure ever-fast NAS performance. To make full use of computing power, the many-core processors in a controller process services concurrently. In addition, intelligent data prefetching and layout further shorten the access latency, achieving over 30% higher NAS performance than the industry benchmark.Linear increase of performance and capacity: Unpredictable business growth requires storage to provide simple linear increases in performance as more capacity is added to keep up with ever-changing business needs. OceanStor Dorado5000/6000 support the scale-out up to 16 controllers, and IOPS increases linearly as the quantity of controller enclosures increases, matching the performance needs of the future business development.Efficient O&M with Intelligent Edge-Cloud Synergy Extreme convergence: Huawei OceanStor Dorado 5000/6000 all-flash storage systems provide multiple functions to meet diversified service requirements, improve storage resource utilization, and effectively reduce the TCO. The storage systems provide both SAN and NAS services and support parallel access, ensuring the optimal path for dual-service access. Built-in containers support storage and compute convergence, reducing IT construction costs, eliminating the latency between servers and storage, and improving performance. The convergence of cross-generation devices allows data to flow freely, simplifying O&M and reducing IT purchasing costs.On and off-cloud synergy: Huawei OceanStor Dorado5000/6000 all-flash systems combine general-purpose cloud intelligence with customized edge intelligence over a built-inintelligent hardware platform, providing incremental training and deep learning for a personalized customer experience. The eService intelligent O&M and management platform collects and analyzes over 190,000 device patterns on the live network in real time, extracts general rules, and enhances basic O&M. Intelligence throughout service lifecycle: Intelligent management covers resource planning, provisioning, system tuning, risk prediction, and fault location, and enables 60-day and 14-day predictions of performance bottleneck and disk faults respectively, and immediate solutions for 93% of problems detected.FlashEver: The intelligent flexible architecture implements component-based upgrades without the need for data migration within 10 years. Users can enjoy latest-generation software and hardware capabilities without investing again in the related storage software features.Always-On Applications with 5-Layer Reliability Industries such as finance, manufacturing, and carriers are upgrading to intelligent service systems to meet the strategy of sustainable development. This will likely lead to diverse services and data types that require better IT architecture. Huawei OceanStor Dorado all-flash storage is an ideal choice for customers who need robust IT systems that consolidate multiple types of services for stable, always on services. It ensures end-to-end reliability at all levels, from component, architecture, product, solution, all the way to cloud, supporting data consolidation scenarios with 99.9999% availability. Benchmark-Setting 5-Layer ReliabilityComponent –SSDs: Reliability has always been a top concern in the development of SSDs, and Huawei SSDs are a prime example of this. Leveraging global wear-leveling technology, Huawei SSDs can balance their loads for a longer lifespan of each SSD. In addition, Huawei's patented anti-wear leveling technology prevents simultaneous multi-SSD failures and improves the reliability of the entire system.Architecture –fully interconnected design: Huawei OceanStor Dorado 5000/6000 adopt the intelligent matrix architecture (multi-controller) within a fully symmetric active-active (A-A) design to eliminate single points of failure and achieve high system availability. Application servers can access LUNs through any controller, instead of just a single controller. Multiple controllers share workload pressure using the load balancing algorithm. If a controller fails, other controllers take over services smoothly without any service interruption. Product –enhanced hardware and software: Product design is a systematic process. Before a stable storage system is commercially released, it must ensure that it meets the demands from both software and hardware, and can faultlesslyhost key enterprise applications. The OceanStor Dorado5000/6000 are equipped with hardware that adopts a fully redundant architecture and supports dual-port NVMe and hot swap, preventing single points of failure. The innovative 9.5 mm palm-sized SSDs and biplanar orthogonal backplane design provide 44% higher capacity density and 25% improved heat dissipation capability, and ensure stable operations of 2U 36-slot SSD enclosures. The smart SSD enclosure is the first ever to feature built-in intelligent hardware that offloads reconstruction from the controller to the smart SSD enclosure. Backed up by RAID-TP technology, the smart SSD enclosure can tolerate simultaneous failures of three SSDs and reconstruct 1 TB of data within 25 minutes. In addition, the storage systems offer comprehensive enterprise-grade features, such as 3-second periodic snapshots, that set a new standard for storage product reliability.Solution –gateway-free active-active solution: Flash storage is designed for enterprise applications that require zero data loss or zero application interruption. OceanStor Dorado5000/6000 use a gateway-free A-A solution for SAN and NAS to prevent node failures, simplify deployment, and improve system reliability. In addition, the A-A solution implements A-A mirroring for load balancing and cross-site takeover without service interruption, ensuring that core applications are not affected by system breakdown. The all-flash systems provide the industry's only A-A solution for NAS, ensuring efficient, reliable NAS performance. They also offer the industry's firstall-IP active-active solution for SAN, which uses long-distance RoCE transmission to improve performance by 50% compared with traditional IP solutions. In addition, the solution can be smoothly upgraded to the geo-redundant 3DC solution for high-level data protection.Cloud –gateway-free cloud DR*: Traditional backup solutions are slow, expensive, and the backup data cannot be directly used. Huawei OceanStor Dorado 5000/6000 systems provide a converged data management solution. It improves the backup frequency 30-fold using industry-leading I/O-level backup technology, and allows backup copies to be directly used for development and testing. The disaster recovery (DR) and backup are integrated in the storage array, slashing TCO of DR construction by 50%. Working with HUAWEI CLOUD and Huawei jointly-operated clouds, the solution achieves gateway-free DR and DR in minutes on the cloud.Technical SpecificationsModel OceanStor Dorado 5000 OceanStor Dorado 6000 Hardware SpecificationsMaximum Number ofControllers3232Maximum Cache (DualControllers, Expanding withthe Number of Controllers)256 GB-8 TB 1 TB-16 TBSupported Storage Protocols FC, iSCSI, NFS*, CIFS*Front-End Port Types8/16/32 Gbit/s FC/FC-NVMe*, 10/25/40/100 GbE, 25/100 Gb NVMe over RoCE*Back-End Port Types SAS 3.0/ 100 Gb RDMAMaximum Number of Hot-Swappable I/O Modules perController Enclosure12Maximum Number of Front-End Ports per ControllerEnclosure48Maximum Number of SSDs3,2004,800SSDs 1.92 TB/3.84 TB/7.68 TB palm-sized NVMe SSD,960 GB/1.92 TB/3.84 TB/7.68 TB/15.36 TB SASSSDSCM Supported800 GB SCM*Software SpecificationsSupported RAID Levels RAID 5, RAID 6, RAID 10*, and RAID-TP (tolerates simultaneous failures of 3 SSDs)Number of LUNs16,38432,768Value-Added Features SmartDedupe, SmartVirtualization, SmartCompression, SmartMigration, SmartThin,SmartQoS(SAN&NAS), HyperSnap(SAN&NAS), HyperReplication(SAN&NAS),HyperClone(SAN&NAS), HyperMetro(SAN&NAS), HyperCDP(SAN&NAS), CloudBackup*,SmartTier*, SmartCache*, SmartQuota(NAS)*, SmartMulti-Tenant(NAS)*, SmartContainer* Storage ManagementSoftwareDeviceManager UltraPath eServicePhysical SpecificationsPower Supply SAS SSD enclosure: 100V–240V AC±10%,192V–288V DC,-48V to -60V DCController enclosure/Smart SAS diskenclosure/Smart NVMe SSD enclosure: 200V–240V AC±10%, 100–240V AC±10%,192V–288V DC, 260V–400V DC,-48V to -60V DC SAS SSD enclosure: 100V–240V AC±10%, 192V–288V DC, -48V to -60V DC Controller enclosure/Smart SAS SSD enclosure/Smart NVMe SSD enclosure: 200V–240V AC±10%, 192V–288V DC, 260V–400V DC,-48V to -60V DCTechnical SpecificationsModel OceanStor Dorado 5000 OceanStor Dorado 6000 Physical SpecificationsDimensions (H x W x D)SAS controller enclosure: 86.1 mm ×447mm ×820 mmNVMe controller enclosure: 86.1 mm ×447mm ×920 mmSAS SSD enclosure: 86.1 mm ×447 mm ×410 mmSmart SAS SSD enclosure: 86.1 mm x 447mm x 520 mmNVMe SSD enclosure: 86.1 mm x 447 mm x620 mmSAS controller enclosure: 86.1 mm ×447mm ×820 mmNVMe controller enclosure: 86.1 mm ×447mm ×920 mmSAS SSD enclosure: 86.1 mm ×447 mm ×410 mmSmart SAS SSD enclosure: 86.1 mm ×447mm ×520 mmNVMe SSD enclosure: 86.1 mm x 447 mm x620 mmWeight SAS controller enclosure: ≤ 45 kgNVMe controller enclosure: ≤ 50 kgSAS SSD enclosure: ≤ 20 kgSmart SAS SSD enclosure: ≤ 30 kgSmart NVMe SSD enclosure: ≤ 35 kg SAS controller enclosure: ≤ 45 kg NVMe controller enclosure: ≤ 50 kg SAS SSD enclosure: ≤ 20 kgSmart SAS SSD enclosure: ≤ 30 kg Smart NVMe SSD enclosure: ≤ 35 kgOperating Temperature–60 m to +1800 m altitude: 5°C to 35°C (bay) or 40°C (enclosure)1800 m to 3000 m altitude: The max. temperature threshold decreases by 1°C for everyaltitude increase of 220 mOperating Humidity10% RH to 90% RHCopyright © Huawei Technologies Co., Ltd. 2021.
