The software installation process for Huawei OceanStor Pacific scale-out storage systems is detailed in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let’s evaluate each option:
- Option A: True. The material states: “For block service installation with converged compute and storage nodes, each node requires at least 20 vCPUs to support management and data processing tasks.”
- Option B: True. The material confirms: “In converged deployments, the disk quantity difference between any two nodes in a storage pool must not exceed 2 or 30% of the disk count on the node with the most disks to ensure balanced performance.”
- Option C: False. The material explains: “Wizard-based software installation automates node addition, network configuration, and control cluster creation via DeviceManager, reducing manual steps. Engineers do not need to perform these tasks manually before installing the OceanStor Pacific software.” This makes the statement incorrect.
- Option D: True. The material notes: “DPC installation requires a minimum of 20 GB of memory on compute nodes to ensure stable operation.”
Thus, option C is false.
