H13-531: HCIE-Cloud Computing V3.0 (Write)

The address conflict check validates address-segment separation across the security services’ DMZ and external O&M planes. It includes DMZ_ECMP2, DMZ_Service_Advance, External_OM, and DMZ_Service so overlapping network ranges are detected before deployment.

CCE uses SAS disks by default for data-plane VM creation. When no SAS disks are available in the data plane, cluster resources cannot be provisioned and cluster creation can fail, so SAS disks must be added.

SSD disks and SSD cards can serve as cache media. When a server has two cache media devices of the same type, the cache capacity is the combined capacity of both devices.

Backup nodes and backup storage are recommended to be deployed in the same cabinet so that backup components have a direct, simplified physical connection layout. Active and standby backup nodes should be separated across cabinets to preserve cabinet-level fault isolation.

HUAWEI CLOUD Stack supports heterogeneous deployment in which an x86 management AZ is paired with either an ARM or an x86 compute AZ. Independent Global deployment separates the Global layer from Region resource pools, while installing a compute AZ remains valid for a Region deployment. The compute-AZ option is turned off only when the deployment is limited to the management AZ. Huawei’s installation guidance identifies that disabling the compute-AZ option hides business-AZ and business-storage settings and limits installation to required services.
