Architecture
FusionSphere OpenStack: The latest version (6.1), based on the community's Mitaka release, includes the Nova, Glance, Ironic, Swift, Cinder, Neutron, Keystone, Ceilometer, and Heat core services.
CPS: A boot and provisioning module responsible for installing OSs on hosts, deploying service modules, monitoring service status, and arbitrating between active and standby services.
FusionSphere OpenStack OM: This unifies the management of resources that are visible to users in the cloud system and provides integrated resource management experience and virtual data centers (VDCs). Automatic resource provisioning is to implement automatic VM deployment, including infrastructure deployment, automatic service deployment, and service monitoring. The O&M system also provides reports, rights, user management, maintenance, and fault management functions.

Extended VM HA: This high availability enhancement was added to meet the elevated reliability requirements of NFV VMs.
VM faults: VM HA is based on the results of VM monitoring. Faults include abnormalities, such as a system panic in the VM GuestOS or an infinite kernel loop.
Server faults: When local VMs cannot be restarted, or when physical servers become faulty, VMs are rebuilt on other physical hosts that meet their requirements.

Shared volumes:
Logical volumes are attached to at least two VMs as shared volumes. Data can be read from or written to one or multiple volumes at the same time.
Scenarios
In consistent data access and hot standby scenarios, failover time is reduced and system availability is improved.

8. Extended flavor APIs define VM bandwidth resources to meet the requirements of virtualized network functions (VNFs). Bandwidth is a core competition resource for products with high bandwidth requirements, such as media servers and gateways. The community natives provide unified management and scheduling for general resources, such as memory and CPUs, but it cannot pre-schedule bandwidth resources, leading to bandwidth preemption. Huawei's release uses nova-compute to update the bandwidth information on each node, extend flavor APIs, define VM bandwidth requirements, and add filters to screen nodes with efficient bandwidth resources in the scheduling phase, so that the high-bandwidth requirements of VNFs can be met.
2. Configure NIC requirements in a flavor
and use the flavor to provision VMs.
1. Update NIC resources on each node.
3. Screen required hosts meeting the bandwidth requirements.

9. Enterprise-Level Enhancements
EVS-supported user-mode high-speed forwarding meets the high performance and low latency requirements of NFV data-plane NEs.
Huawei high-performance user-mode EVS is seamlessly connected to the FusionSphere OpenStack network virtualization service based on ML2 plug-ins in the standard of FusionSphere OpenStack Neutron, and this user-mode EVS provides tenants with high-performance, low-latency virtual switching. It uses the high-performance Data Plane Development Kit (DPDK) user-mode forwarding framework to bypass data packets from physical NICs to the tenant plane. VMM employs the vhost-user technology to ensure the high-performance, low-latency packet processing between VMs and hosts, or among VMs.

Automatic network orchestration by the SDN controller
FusionSphere OpenStack cloud platform builds a multi-virtualization platform (ESXi and Huawei XEN and KVM) and converged resource pools with automatic Bare Metal Server provisioning. It coordinates with Huawei SDN controller to automatically orchestrate end-to-end overlay network services, which are based on hardware and software SDNs.

11. Enterprise-Level Enhancements
Huawei FusionSphere OpenStack matches E2E O&M tool systems (used for development and test, project delivery, and O&M) to meet the O&M requirements of production-oriented E2E processes.
