Storage space usage of OceanStor 9000 when erasure coding technology is used
When the erasure coding (EC) technology is used, OceanStor 9000 calculates the storage space usage based on the following principles: 1. The system security space is 90%. 2. When small files are stored, file metadata takes up about 8% space of OceanStor 9000. When large files are stored, file metadata takes up insignificant space. For example, in 4+2 redundancy mode, the maximum storage space usage is calculated as follows: (1) Small file storage space usage = 90% x (1 �?8%) x 66.7% = 55% (2) Large file storage space usage = 90% x 66.7% = 60%
