[St. Louis, USA, November 18, 2021] Huawei OceanStor Pacific Storage (Huawei HPDA Lab) took second place in the IO500 list,which is one of the world’s leading HPC storage performance rankings.

Huawei OceanStor Pacific storage is a next-gen intelligent distributed storage that has been put into large-scale commercial use worldwide thanks to its:

Strong support for hybrid workloads: Working with OceanFS, a Huawei-developed parallel file system, this distributed storage system uses a series of cutting-edge technologies such as directory DHT partitioning, large I/O passthrough and small I/O aggregation, and multi-granularity disk space management to provide high bandwidth for large files and high IOPS for small files. This meets different needs of different hybrid workloads.

Reliable data protection: OceanStor Pacific leverages Erasure Coding (EC) technology that implements N+M data protection, ensuring enterprise-grade data reliability and availability, while also offering more available capacity and higher resource utilization.

The IO500® is one of the world’s leading HPC storage performance rankings. It has been widely recognized by research institutions, including universities, national laboratories, and commercial companies. Since November 2017, the IO500 list has been released at the top HPC conferences (SC in the US and ISC in Germany). Against this backdrop, I/O performance has become an important indicator for measuring the efficiency of supercomputer applications. Specifically, it measures storage performance using two key indicators: data bandwidth (GB/s) and read/write speed (IOPS). Storage systems are evaluated by simulating different I/O models, from light to heavy workloads. Scores are obtained from the geometric mean of performance values across all scenarios. By limiting the benchmark to 10 nodes, the test challenges single-client performance from the storage system. The 10-node list is a good reference framework for users because it closely represents the scale that an actual parallel program can achieve and better reflects the I/O performance that the storage system can provide in real-world application.
