1. What, exactly, is the novel about the Huawei OceanStor Dorado All-Flash Storage innovation?

Huawei's all-flash storage series sets a new benchmark for next-gen unified all-flash storage. Remarkable innovations and upgrades in three main areas – service performance, architecture stability, and O&M intelligence – help it remain lightning-fast, highly reliable, and always intelligent.

1) Innovative Hardware for High Performance
Huawei's innovative hardware implements E2E storage system acceleration. The NoF+ Solution uses intelligent lossless Ethernet to build a high-performance storage network with zero packet loss even at full bandwidth scenarios, improving performance by 42% compared to traditional FC. The controller enclosure integrates 5 types of intelligent hardware to accelerate key data transmission paths and build high-performance storage computing power. The all-flash+SCM high-performance storage media significantly improve data read/write performance. In addition, the unique, intelligent FlashLink 2.0 algorithms with disk-enclosure collaboration also help deliver the industry-leading 21 million IOPS and 0.05 ms latency.
2) Always-On Applications with 5-Layer Reliability
The OceanStor Dorado All-Flash Storage features global wear-leveling and anti-wear leveling at the disk level, leading fully-interconnected architecture, system-level RAID virtualization and three-disk failure tolerance, solution-level gateway-free active-active design, and cloud-level data protection and disaster recovery on and off clouds to achieve the industry's only active-active solution for both SAN and NAS. Huawei's unique fully-interconnected architecture ensures that services are not disrupted in the event of a controller failure. In fact, services will continue to run even if 7 out of 8 controllers fail; as long as one controller is functioning, core enterprise services can continue to run stably.

3) Efficient O&M with Intelligent Edge-Cloud Synergy
Storage and compute convergence make data processing more efficient, while convergence across different generations allows for effortless data migration. In addition, intelligent self-tuning and cloud-based management coordinate with each other. Lastly, the built-in intelligent cache algorithm improves cache hit ratio by 50%, and 3-layer intelligent data management and general-purpose cloud intelligence streamline O&M and management throughout the entire product lifecycle.

2. How does Huawei OceanStor Dorado All-Flash Storage break with conventional ideas or processes in its field?

Huawei’s next-generation all-flash storage goes one step further by delivering industry-leading performance for mission-critical services through:

1) NoF+ (NVMe over RoCE)
Huawei's industry-leading NoF+ technology uses native NVMe architecture to support E2E high concurrency and a shorter protocol path. This helps to unleash the power of flash memory and achieve ultra-high performance and ultra-low latency. The innovative hardware platform and E2E acceleration help to deliver 21 million SPC-1 IOPS and 0.05 ms latency — a performance increase of almost 30%. Meanwhile, the intelligent lossless Ethernet uses built-in algorithms to dynamically adjust the watermark, ensuring zero packet loss at 100% throughput and higher performance. Compared to the traditional Ethernet that achieves failover in 5 to 10 seconds, the FC network supports active/standby failover in seconds without affecting host services. Furthermore, the innovative device plug-and-play and all-IP data center network simplify O&M.

2) Fully interconnected architecture design
Using the brand-new fully-interconnected architecture, OceanStor Dorado All-Flash Storage implements a fully symmetric active-active solution. The front-end and back-end networks are all IP-interconnected and support 100GE RoCE interconnection. Compared with traditional high-end storage systems, Huawei all-flash storage systems are considerably more stable. Services will continue to run even if 7 out of 8 controllers fail; as long as one controller is running, services are always on. The fully interconnected architecture greatly improves the E2E reliability and achieves 99.9999% availability, making it particularly suitable for mission-critical applications in industries such as finance, manufacturing, and carriers.

3) Active-active solution for SAN and NAS
OceanStor Dorado All-Flash Storage implements the industry's only gateway-free active-active solution for SAN and NAS. This means one device system provides both SAN and NAS services, thus reducing the device quantity and improving overall performance. The unified arbitration mechanism ensures that the arbitration results are consistent, making it possible for SAN and NAS to run on the same device. OceanStor Dorado All-Flash Storage also supports automatic restoration of the active-active relationship and automatic O&M. It also allows for a smooth online upgrade to the active-active and geo-redundant 3DC solution featuring serial/parallel/DR star networking. This ensures zero service disruption and meets the key service requirements of databases and files in sectors like healthcare and finance.

3. How does it go beyond marginal improvements on something that already exists?

Employing a range of advanced technologies, Huawei OceanStor Dorado All-Flash Storage improves storage reliability and reduces data center costs and energy consumption:

1) Global SSD wear-leveling and Huawei-patented anti-wear leveling
These two technologies reduce the risk of multi-SSD failures, extend SSD lifespans, and improve system reliability. Global wear leveling uses Huawei RAID 2.0+ to evenly distribute data across all SSDs based on fingerprints and balance the wear degree. When multiple SSDs are close to the wear limit, the global anti-wear leveling technology selects an SSD and increases its service volume to prevent collective failures and enhance reliability.

2) Cross-enclosure RAID tolerating failure at the disk enclosure level
The cross-enclosure RAID tolerates the failure of a single disk enclosure without disrupting services. RAID-TP can lose one enclosure and tolerate the failure of one more SSD without disrupting services. This is in contrast to the typical industry-wide tolerance of only one disk enclosure.

3) Innovative Palm-sized disks and high-density disk enclosures
Compared to the traditional 25-disk slot enclosure, the innovative 36-slot high-density enclosure increases the disk quantity by 44% per unit space. Huawei's innovative Palm-sized disks are the industry's thinnest external SSDs, saving almost 37% more space. The patented horizontal backplane design reduces interference between the back-end disk connectors and mainboard connectors and improves heat dissipation by 25%. These help to reduce both device investment and energy consumption costs.
