OceanStor N8500

Huawei OceanStor N8500 clustered NAS storage system is a leading higher performance NAS storage. It meets the service requirements of governmental, educational and scientific research, digital media and telecom carriers for high performance, high expansion, effective data management and unified storage.

With rapid progress in information industry, data witnesses a sharp growth, and the growth speed of unstructured data far exceeds the expectation. Unified & centralized storage and effective & simple management for mass storage is required to better support the sustainable growth of services. Markets pose new challenges to the performance, scalability, efficiency, and application scenarios of the storage system. Huawei OceanStor N8500 clustered NAS storage system is a leading higher performance NAS storage. It provides high performance, high expansion, effective data management, and unified storage.

High Performance

  • Leading performance: The storage system provides top performance in the SPECsfs2008 benchmark. When the NFS protocol is used, performance reaches 3,064,602 OPS.
  • Cluster architecture: Multi-node Active-Active cluster technology is used. In the cluster, all nodes work in a cooperative manner to implement concurrent data access.
  • Globally shared storage: All nodes can access the same storage at the same time. Through the intelligent DNS it can balance load to each node, improving node resource utilization
  • Highly reliable architecture: Redundant components prevent single points of failure. Software technologies such as data coffer and file system mirror further improve system reliability.


  • Expansible engine node: Engine nodes can be smoothly expanded online to 24 nodes. System performance improves with the addition of engine nodes.
  • Expansible storage capacity: Storage capacity can be expanded to 15 PB.


  • Dynamic Storage Tiering (DST): Bidirectional dynamic migration is implemented between different storage media based on file access frequency and time policy. It is transparent to applications and reduces enterprise CAPEX.
  • Smartcache: By using flash drivers to extend the cache and cooperating with the dynamic data cache technology, improve the system performance
  • File system mirror : In certain storage systems, a file system mirror can be set to store multiple data file systems and improve online data reliability.
  • Soft/hard quota management: This implements flexible user space allocation and use.
  • Domain management: AD/NIS/LDAP is supported.
  • Multiple protection technologies: Provide multiple value-added features such as snapshot, copy, remote replication


  • Unified protocols: Unified storage refers to unified storage of the SAN or NAS storage protocol. Certain storage systems support structured and unstructured data storage. Multiple storage network protocols such as iSCSI, FC, FCoE, NFS, CIFS, HTTP, and FTP are supported.
  • Unified management: A simple graphical interface provides a unified way to manage files and block data services. A wizard configuration mode helps complete configurations easily.
  • Device monitoring: The graphical management interface provides real-time/historical performance measurement and supports multiple alarm modes such as audible alarms, visual alarms, and email alarms. A device’s operating status can be monitored at any time.
