Huawei OceanStor N8500
Huawei’s OceanStor N8500 clustered NAS storage system is a leading unified storage platform oriented to high-end and medium-range applications. It meets the service requirements of telecommunications operators, digital media, high-performance computing, governmental entities, and educational and scientific research industries. It provides 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. The OceanStor N8500 clustered NAS storage system is a leading unified storage platform oriented to high-end and medium-range applications, offering mutilates features including high performance, high expansibility, high reliability, efficient management data and so on.
- 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: Multinode 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. The engine node provides the load balancing function. After load balancing is implemented, the load caused by hot-spot data access is evenly distributed to all nodes. This improves access efficiency of hot-spot data.
- 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.
- File system capability: Maximum file system space is 256 TB. Each file system supports up to 1,000,000,000 files.
- 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.
- File system mirror function: 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.
- Backup solution: The Symantec NetBackup Client can be embedded in the NAS engine node to optimize backup performance and shorten the backup window.
- 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.
- File-level data protection technology: Snapshot, snapshot recovery, and remote replication functions at the file system level provide multilevel data protection.
- Block-level data protection technology: Smart Cache dynamic data cache technology and value-added features such as LUN-based snapshot, copy, and synchronous/asynchronous remote replication are provided for block-level data
