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.
    NOTE:
    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).
    NOTE:
    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.
