Huawei OceanStor Pacific Series Storage Application
1. What, exactly, is novel about the product or innovation?
Based on a unified data platform, the OceanStor Pacific series provides four types of services: block, file, object, and HDFS. With remarkable achievements in technological innovation and upgrade, it delivers superior application performance, high process efficiency, and low storage costs.
1） Hybrid workloads-oriented
Based on next-gen storage architecture, the OceanStor Pacific series employs innovative techniques such as metadata layout optimization, separate processing of large and small I/Os, intelligent disk granularity management, CPU partitioning, and CPU core allocation. One storage system provides both high bandwidth and IOPS to easily handle ever-increasing application workloads. A maximum of 32 GB/s bandwidth and 400,000 IOPS per U deliver industry-leading performance.
The OceanStor Pacific series provides POSIX and MPI-IO access capabilities through Distributed Parallel Client (DPC). DPC can connect to multiple storage nodes at the same time, breaking single-thread and single-client performance bottlenecks. The single-thread bandwidth of up to 8 GB/s is also industry-leading.
Workloads generated in different phases of an application process usually have different characteristics. As a result, a customer may need to use storage products from different vendors to cope with these workloads, incurring various problems such as multiple data copies, complex management, and imbalanced storage utilization. The hybrid workloads-oriented capability of the OceanStor Pacific series can effectively solve these problems to improve resource efficiency.
2） High-density design
OceanStor Pacific 9950 is a high-density NVMe all-flash storage model. Each 5 U chassis can house a maximum of 8 storage nodes, totaling up to 80 NVMe SSDs, 614.4 TB raw capacity, 160 GB/s bandwidth, and 2 million IOPS for ultra-fast data access. Typically, one 5 U chassis can meet most customers' performance needs.
OceanStor Pacific 9550 is a high-density capacity storage model. Each 5 U chassis accommodates 2 storage nodes and 120 x 3.5-inch large-capacity HDDs, offering a raw capacity of up to 1680 TB. It reduces the cabinet footprint by 62.5% compared to general-purpose storage servers. It is the perfect choice for handling mass data.
With the 22+2 high-ratio EC capability, the OceanStor Pacific series provides up to 91.6% storage utilization. OceanStor Pacific 9950 and OceanStor Pacific 9550 can form an intelligent tiered storage solution to further reduce the cost of mass data storage.
The OceanStor Pacific series can provide file, object, and HDFS services at the same time. This enables the same data to be accessed over different protocols without data migration, greatly improving data utilization and reducing storage space occupation in emerging scenarios such as data lakes and high-performance data analytics (HPDA).
Thanks to the unified unstructured data platform, the multi-protocol interworking feature enables file, object, and HDFS storage services to inherit their own semantics and share diverse enterprise-grade features while improving performance. It does not require any additional gateways or plug-ins. This series is the first in the industry to implement multi-protocol interworking without compromising performance or protocol semantics.
2. How does the product break with conventional ideas or processes in its field?
Huawei OceanStor Pacific storage uses the following advanced innovations to improve the efficiency in storing and transferring mass data. Seamless multi-protocol interworking
1）Multi-protocol interworking implemented by most competitors in the industry is typically based on file or object storage, where other protocols are implemented through gateways or plug-ins. The performance and semantics are limited by the file or object storage platform. As a result, the semantics of other protocols cannot be fully implemented, delivering much lower performance than the native semantics. Moreover, applications need to be modified for adaptation.
By contrast, OceanStor Pacific's multi-protocol interworking capability is based on a unified unstructured data platform. File, object and HDFS services share unified metadata and data, and all of the services can provide native, full semantics without performance loss. It's worth mentioning that OceanStor Pacific implements multi-protocol interworking without using additional gateways or plug-ins, and upper-layer applications do not need to be modified either. What's more, multiple protocols can share various enterprise-grade features of the storage platform to achieve better data protection.
2） High bandwidth and IOPS
Some of the mainstream storage products in the industry are good at handling bandwidth-intensive workloads, such as DDN EXAScaler and EMC PowerScaler, while some others are good at dealing with IOPS-intensive workloads, such as NetApp FAS and PureStorage FlashBlade. However, very few can provide high bandwidth and IOPS at the same time. As a result, customers in need of both high bandwidth and IOPS have no alternative but to purchase different storage products.
The OceanStor Pacific is designed for both bandwidth- and IOPS-intensive workloads. Powered by DPC, NVMe all-flash media, and innovative techniques such as metadata layout optimization, separate processing of large and small I/Os, intelligent disk granularity management, CPU partitioning, and CPU core allocation, the OceanStor Pacific provides up to 160 GB/s bandwidth and 2 million IOPS within merely 5 U space to ensure ultra-fast data access. One storage system is sufficient to handle complex workloads.
3. How does it go beyond marginal improvement on something that already exists?
Huawei OceanStor Pacific 9550 features a range of innovative technologies that help overcome the challenges of mass data:
1） High-density capacity hardware
Some high-density storage systems in the industry use controllers and high-density JBODs (90/106 disks in 4 U) to increase their capacity density; however, they encounter difficulties in capacity expansion and O&M. Others use a fully symmetric distributed architecture for easy management and O&M but achieve low density (60/80 disks in 4 U).
OceanStor Pacific 9550's high-density capacity hardware stands out from the competition by using a fully symmetric distributed architecture to increase the hardware density to 24 disks per U (120 disks in 5 U). To improve heat dissipation and simplify O&M for high-density hardware, OceanStor Pacific 9550 adopts a series of innovative designs:
− A tank chain + bidirectional drawer enables a 75% lower center of gravity shift compared to the normal structure of one-way drawers. This allows for easy O&M.
− No holding rails + concealed cabling allow the system to be placed in a 1.1 m deep cabinet to reduce space occupation.
− Dual-layer air channels (disks on the top and the main control board on the bottom) prevent the main components from affecting each other, doubling reliability.
− A carbon fiber pad + VC heat spreader enhances heat dissipation by 20% and decreases the CPU temperature by 11°C.
2） Innovative half-palm NVMe SSD
Compared with the traditional 2.5-inch SSD, the Huawei-developed half-palm NVMe SSD reduces the thickness of a single disk by 37% and allows 33% more disks in each U (from 12 to 16 disks), making high-density storage design possible. The half-palm NVMe SSD uses a full metal case with a thermal conductivity coefficient of over 200 W/mK, reducing the operating temperature of flash chips by 5ºC compared to other materials.
4. How do customers benefit from the product or innovation?
Huawei's next-gen OceanStor Pacific storage helps customers unleash the business value. One device provides multi-protocol interworking and high performance for hybrid workloads. In typical scenarios, the processing efficiency is improved by 30+%. Compared with general-purpose servers, the high-density design adopted by the OceanStor Pacific reduces the cabinet footprint by 62.5% and the TCO by 20+%. The OceanStor Pacific has been used in a wide range of scenarios such as HPC, big data analytics, backup, archiving, and virtual resource pools. For instance, Lundin Energy Norway Embraces a New Era of Deep-Sea Exploration with Huawei OceanStor Pacific Storage. Lundin Energy Norway is the largest independent European exploration and production company, with a market value of more than $7.6 billion. One OceanStor Pacific storage system provides both high bandwidth and IOPS, and supports Lundin's seismic data processing, interpretation, and simulation analytics, improving data processing efficiency by 28%. Moreover, intelligent tiering of hot and cold data saves 73% physical storage space and slashes the overall TCO by 35%.
