Software Architecture

Software Architecture

The OceanStor 9000 combines all physical storage nodes (storage nodes or nodes for short) into a cluster. It provides various services in a cluster mode, including the Object Storage Service.

Figure 1-1 shows the software architecture of the OceanStor 9000.

Figure 1-1  Software architecture

The OceanStor 9000 software architecture in Figure 1-1 is described as follows:

  • The object storage service runs on all storage nodes that enable it, and metadata is evenly distributed to avoid performance bottlenecks caused by a concentration of the metadata in one node. Storage nodes can be flexibly added and a single system can be up to 100 PB.
  • The OceanStor 9000 cluster employs one master node and one slave node as management nodes to manage accounts and users of the object storage service.
    Management nodes can only be viewed on DeviceManager. The nodes whose Role is management are management nodes.
  • The object storage service supports RESTful APIs, clients can access the OceanStor 9000 and store data by the object storage RESTful APIs (compatible with Amazon S3 APIs).
    These clients can be regarded as the Internet-based object storage applications and are provided or developed by users of OceanStor 9000. The clients can be application software or visual websites.
  • Administrators can securely access DeviceManager and SystemReporter through HTTPS to manage system resources and monitor system status and performance. Besides, the DeviceManager supports RESTful APIs.
  • The OceanStor 9000 can be connected to external NMSs that are based on the SNMP protocol and the SMI-S protocol.
