Infrastructure

Infrastructure includes servers, storage devices, and network devices required by data centers. This layer provides multiple types of hardware deployment architecture based on different service requirements.

Resource pools

Resource pools are built upon the physical infrastructure, which are classified into computing, storage, and network resource pools.

FusionSphere OpenStack provides the resource pooling and management capabilities for virtual computing, virtual storage, and virtual networks, and provides management capabilities of resource pools.

• Virtualization pool
• Bare metal server pool
• Block storage pool
• File storage pool
• Network resource pool
• DR storage pool
• Backup storage pool
• SAP Cloud resource pool
• FusionStage pool (invoked by the ServiceStage cloud service)
• Resource pool - hybrid cloud pool

Other resource pools:

• Object storage pool: OBS services directly invoke object storage pools (without passing through FusionSphere OpenStack).
• Big data pool: HDS and ADS services directly invoke the big data pool (without passing through FusionSphere OpenStack).
• Database pool: RDS and Oracle Database Service directly invoke the database pool (without passing through FusionSphere OpenStack).
• Two-level cloud resource pool: In Region Type I, Region Type II, and Region Type III scenarios, the peer FusionCloud resource pool can be interconnected with the local resource pool.
• Resource pool of the management plane hybrid cloud: In Region Type I, Region Type II, and Region Type III scenarios, public cloud resources are connected to the FusionCloud through the API adaptation.
• Resource pool of VMware inventory management: In Region Type I, Region Type II, and Region Type III scenarios, VMware services directly invoke the resource pool of VMware inventory management (without passing through FusionSphere OpenStack).
• Resource pool of Hyper-V inventory management: In Region Type I, Region Type II, and Region Type III scenarios, Hyper-V services directly invoke the resource pool of Hyper-V inventory management (without passing through FusionSphere OpenStack).
• Resource pool of Power inventory management: In Region Type I, Region Type II, and Region Type III scenarios, Power service directly invokes the resource pool of Power inventory management (without passing through FusionSphere OpenStack).
• Virtual resource pool: In Region Type I, Region Type II, and Region Type III scenarios, virtual resource pools are centrally managed by FusionManager in FusionCloud, and cloud service resources, such as ECSs and EVS disks, in virtual resource pools managed by FusionManager are synchronized.

Management domain

Uses ManageOne to provide unified management and scheduling of multiple cloud DCs.

• Operation management: The ManageOne operation plane provides unified operation management for cloud services to improve the service operation agility and efficiency.
• O&M management: The ManageOne OM plane provides unified O&M management for virtual resources and physical resources to improve O&M efficiency.

Cloud services

Centrally manage resources provided by the resource pool layer of multiple DCs. Table 1-1 in Cloud Services and Common Components provides details about each cloud service and common component. Common components provide common capabilities for cloud services, for example, providing a unified operating system EulerOS.

Application domain

Applications are provided by the third party. Based on cloud services provided in FusionCloud, this layer customizes service systems to meet users' service requirements.
