OceanStor Pacific 9550 High-Density, Large-Capacity Distributed Storage

OceanStor Pacific 9550 is a high-density, large-capacity storage system that provides cost-effective data storage services. Each 5 U chassis houses 2 storage nodes and uses HDDs as large-capacity primary storage. Each chassis provides a raw capacity ranging from 720 TB to 1680 TB, reducing the cabinet footprint by 62.5% compared to general-purpose storage servers. It is suitable for mass unstructured data storage and can work with OceanStor Pacific 9950 (a high-density performance model) to build a tiered storage solution, maximizing the return on investment. Its key features are as follows:

• The dual-layer air channel design and counter-rotating fans reduce the component failure rate by 50% compared to the conventional mode.
• Carbon-fiber thermal pads and VC phase-change heat dissipation improve the heat dissipation capability of the entire system by 20% compared to the conventional mode.
• A full field replaceable unit (FRU) design is adopted to allow 24/7 non-disruptive maintenance.

With an industry-leading capacity density, OceanStor Pacific 9550 provides high-availability data access services for scenarios such as HPC, AI applications, big data analytics, and long-term backup and archiving of mass data.
