To meet the customer's requirement for departmental isolation and resource control, Huawei recommends the combination of Multi-tenancy (Option C) and Quotas (Option D).12

Multi-tenancyis the foundational feature for iso3lation in Huawei object storage. It allows the physical storage system to be logically partitioned into multip4le "Tenants". Each department can be assigned its own tenant environment with its own set of users, access keys, and buckets. Data is logically isolated, meaning one department cannot see or access the data of another unless explicitly permitted.

Quotamanagement is then used to limit the capacity consumed by each department. In Huawei OceanStor Pacific, quotas can be applied at the Tenant level or the Bucket level. By setting a Tenant Quota, the administrator ensures that a specific department does not exceed its allocated budget of storage space, preventing one department from exhausting the resources of the entire system. While Replication (Option A) and WORM (Option B) are valuable for data protection, they do not address the specific needs of departmental isolation and capacity limiting.
