Huawei's OceanStor hybrid flash storage system can not only provide high-performance storage services for application servers, but also support various advanced data preparation and disaster recovery technologies to ensure profitable and safe operation of data services.

A company purchased a set of Huawei hybrid flash storage equipment to provide NAS (Network Attached Storage) services for the three departments of finance, personnel and technology. The current network environment is as follows:
1) The clients are all Windows operating systems and join the same AD (Active Directory) domain;
2) The clients and storage systems of the three departments are in the same local area network.

1) Each of the three departments uses 1TB of dedicated storage space;
2) Each employee can read and write to their own private directory;
3) Private directories between employees are invisible to each other.
