Which of the following statements are correct about multi-tenancy of object storage?
Correct Answer: B,C,D
Multi-tenancy is used in object storage to allow different departments, services, or customers to share one physical storage system while remaining logically isolated. Option B is correct because multiple departments can use the same platform instead of deploying separate storage silos. Option C is correct because each tenant can be assigned independent capacity quotas and performance QoS policies, preventing one tenant from consuming excessive resources or affecting another tenant's service quality. Option D is also correct because tenants share the same backend storage pool, which improves overall resource utilization and reduces wasted capacity. Option A is incorrect because tenant isolation is a core purpose of multi-tenancy. One tenant should not be able to view or access another tenant's data unless explicit authorization is configured.
Question 42
OceanStor Dorado supports only SAS SSDs.
Correct Answer: B
OceanStor Dorado supports multiple types of SSDs, including NVMe and SAS SSDs. NVMe SSDs provide higher performance and lower latency compared to SAS SSDs, and OceanStor Dorado is designed to leverage these advanced SSD options for enhanced performance.
Question 43
Each LUN on OceanStor Dorado is owned by a specific controller.
Correct Answer: B
Unlike traditional storage architectures that use an Asymmetric Logical Unit Access (ALUA) model where a LUN is " owned " by a primary controller, Huawei OceanStor Dorado utilizes a Symmetric Active-Active architecture. In this design, LUNs do not have a specific owner. Instead, all controllers in a cluster can simultaneously receive and process I/O requests for the same LUN. This is made possible by the SmartMatrix full-mesh interconnect , which allows any interface module to communicate with any controller, and any controller to access any disk. Because there is no concept of " LUN ownership, " there is no need for time-consuming " LUN handovers " if a controller fails. This symmetry eliminates performance bottlenecks, ensures balanced load distribution across all hardware resources, and provides a smoother experience for host-side multipathing software. This architectural shift is a key differentiator for the Dorado series, enabling it to deliver consistent, high-speed performance even during controller maintenance or failure.
