OceanStor Pacific 9550 High-Density, Large-Capacity Scale-out Storage

OceanStor Pacific 9550 storage system uses Hard Disk Drives (HDDs) as its primary storage to provide cost-effective data storage services. Each 5U chassis houses two storage nodes, providing a raw capacity range of 720 TB to 1920 TB, which reduces the cabinet physical footprint by 62.5% compared to general-purpose storage servers.

Purpose-designed for mass unstructured data storage, this storage system is compatible with OceanStor Pacific 9950 — a high-density performance model — to build a tiered storage solution, maximizing the Return On Investment (ROI).

Compared to conventional modes, the system's dual-layer air channel design and counter-rotating fans reduce the component failure rate by 50%, while carbon-fiber thermal pads and Vapor Chamber (VC) phase-change heat dissipation improve the heat dissipation capability of the entire system by 20%. In addition, 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 High-Performance Computing (HPC), Artificial Intelligence (AI) applications, big data analytics, and long-term backup and archiving of mass data.
