The multi-tenant feature in Huawei’s flash storage systems, such as OceanStor Dorado, is designed to

isolate resources for different tenants to ensure data security and privacy. The *HCIP-Storage V5.5

Training Material (Module 2: Flash Storage Technologies)* explains: “The multi-tenant feature

isolates both block and file resources, ensuring that tenants cannot access each other’s LUNs or file

systems. This is achieved through logical partitioning and access control mechanisms.” The

statement in the question claims that tenants cannot access each other’s LUNs but can access each

other’s file systems, which contradicts the official documentation. The material emphasizes that file

systems, like LUNs, are isolated per tenant, and cross-tenant access is prevented unless explicitly

configured (e.g., through shared namespaces, which is not the default behavior). Therefore, the

statement is false.
