Wushan file system manages the underlying data as an object, simplifying management methods and metadata overhead

Wushan file system adopts object storage mode, and does not need to provide users with traditional file system tree structure for users to use.

The data object of the Wushan file system consists of a set of Stripes, and the strips have Erasure Code matrix operations.

Each object of the Wushan file system is a combination of data and data attribute sets. The data attributes can be set according to the needs of the application, including data distribution, quality of service, and so on.

If you do not need to distinguish users who restrict access to the shared directory, you can choose normal sharing.

If you do not need to distinguish users who restrict access to the shared directory, you can choose homeedir sharing.

In normal mode, the client can only access the share through one VIP.

The Oceanstor 9000 system can configure different data protection levels for different directories/files.

When writing data to the Oceanstor 9000 system, it will first divide the Chunk by size.

For every N chunks, the check block of M chunks is calculated according to the ErasureCode algorithm.

The utilization of the protected data space is about N/(N+M), and the reliability of the data is determined by the M value. The larger the M, the higher the reliability.
