Ever Fast Performance with Innovative Hardware

Innovative hardware platform:

Huawei storage uses an innovative hardware platform for E2E data  acceleration, delivering the IOPS of 40,000,000.

● The intelligent multi-protocol interface module hosts the protocol parsing previously performed by the general-purpose CPU,expediting the front-end access performance by 20%.
● The computing platform offers industry-leading performance with 25% higher computing power than the industry average.
● The intelligent accelerator module analyzes and understands I/O rules of multiple application models based on machine learning frameworks to implement intelligent prefetching of memory space.
● This improves the read cache hit ratio by 50%. SmartCache + SCM intelligent multi-tier caching identify whether or not the data is hot and uses different media to store it, reducing the latency by 60% in OLTP (100% reads) scenarios.
● The intelligent SSD hosts the core Flash Translation Layer (FTL) algorithm, accelerating data access in SSDs and shortening the write latency by half.
● The intelligent hardware has a built-in Huawei storage fault library that accelerates component fault location and diagnosis, and shortens the fault recovery time from 2 hours to just 10 minutes.

Intelligent algorithms:

Most flash vendors lack E2E innate capabilities to ensure full performance from their SSDs. OceanStor Dorado 6800/18500/18800 run industry-leading FlashLink® intelligent algorithms based on self-developed controllers, disk enclosures, and operating systems.

 Many-core balancing algorithm: Taps into the many-core computing power of a controller to maximize the data processing capability.
Service splitting algorithm: Offloads reconstruction services from the controller enclosure to the smart SSD enclosure to ease the load pressure of the controller enclosure for more efficient I/O processing.
Cache acceleration algorithm: Accelerates batch processing with the intelligent module to bring intelligence to storage systems during application operations.

The data layout between SSDs and controllers is coordinated synchronously.

Large-block sequential write algorithm: : Aggregates multiple discrete data blocks into a unified big data block for disk flushing, reducing write amplification and ensuring stable performance.
Independent metadata partitioning algorithm: Effectively controls the performance compromise caused by garbage collection for stable performance.
I/O priority adjustment algorithm: Ensures that read and write I/Os are always prioritized, shortening the access latency.

FlashLink® intelligent algorithms give full play to all flash memory and help Huawei OceanStor Dorado achieve unparalleled performance for a smoother service experience.

E2E NVMe architecture for full series:

All-flash storage has been widely adopted by enterprises to upgrade existing IT systems, but always-on service models continue to push IT system performance boundaries to a new level. 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 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 OceanFS:

The OceanStor Dorado 6800/18500/18800 high-end 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 Dorado 6800/18500/18800 support the scale-out up to 32 controllers, and IOPS increases up to 21,000,000 linearly as the quantity of controller enclosures increases, matching the performance needs of the future business development.

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. OceanStor Dorado 6800/18500/18800 high-end all-flash storage systems are an ideal choice for customers who need robust IT systems that consolidate multiple types of services for stable, always on services. They ensure end-to-end reliability at all levels, from component, architecture, product, solution, all the way to cloud, supporting data consolidation scenarios with 99.99999% availability.

Benchmark-Setting 5-Layer Reliability Component – 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 6800/18500/18800  use full-interconnection design at front and back-ends and intelligent multi-protocol interface modules to build the SmartMatrix architecture with ultra-high reliability. High-speed interconnection of multiple controllers is supported via the 100 Gb/s RDMA protocol, and the unique full-interconnection design tolerates failures for 3 out of 4 and even 7 out of 8 controllers and failure for 1 out of 2 controller enclosures to ensure zero service interruption, setting a new benchmark for storage reliability. The front-end interface modules connect to 4 controllers simultaneously. If a controller fails, services can be switched to an operational controller in seconds, without any host link interruption or any impact on upper-layer services.The storage architecture adopts a fully symmetrical A-A design， 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 faultlessly host key enterprise applications. The OceanStor Dorado 8000/18000 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 15 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.
