1 Introduction to FusionSphere
1.2 FusionSphere Characteristics and Functions
Openness
Developed based on the native OpenStack architecture, FusionSphere is compatible with
mainstream computing, storage, and network devices, thereby avoiding vendor lock-in risks.
It also provides standard OpenStack application programming interfaces (APIs), facilitating
interconnection and integration with products from third-party vendors.
Flexibility
FusionSphere uses the service-oriented architecture (SOA), which allows users to flexibly add
and reduce functions based on service requirements.
High Reliability
FusionSphere improves system reliability to provide a carrier-class cloud computing platform
by employing the following methods:

All management services are deployed in active/standby or load sharing mode to prevent
single points of failure (SPOFs).

Management data is stored in active/standby mode and is periodically backed up, thereby
enhancing data reliability.

The physical network is divided into multiple logical network planes, which are isolated
by virtual local area network (VLAN), thereby ensuring data transmission reliability and
security.
Easy Maintenance
FusionSphere provides multiple automated operation and maintenance (O&M) functions,
such as automatic batch installation and deployment, automatic capacity expansion, system
upgrade and patching, system status monitoring and alarm reporting. All these functions
improve system O&M efficiency and reduce maintenance costs.

4.1 Converged Resource Pools
In cloud data center scenarios, FusionSphere uses the FusionCompute hypervisor to provide
high-performance, high-reliability VMs for users. It can also manage third-party virtualization
platforms, such as VMware's hypervisor, providing an interface for managing heterogeneous
virtual resources in a unified manner.

4 Key Features
4.2 Distributed Resource Scheduling and Automatic
Power Management
FusionCompute intelligently schedules virtual resources to balance system loads, thereby
ensuring high system reliability and availability, improving the resource utilization of the data
center, and optimizing user experience.
4.3 VM Migration
FusionSphere allows VMs to be migrated between different servers without interrupting user
services, if only the servers meet the service resource requirements.
4.4 VM Resource Adjustment
FusionSphere allows adjustment of VM resources, such as the numbers of VCPUs and virtual
network interface cards (NICs), and the memory and storage disk space. The adjustment of
some resources may require the VMs to stop first.
4.5 Network Resource Pools
FusionSphere allows flexible management of virtual network resources, such as subnet pools,
virtual local area network (VLAN) pools, MAC address pools, and security groups, based on
the service requirements.
4.6 Network Plane Bandwidth Control
FusionSphere supports network plane bandwidth control by allocating specified bandwidths
to the management plane, storage plane, and service plane based on the physical bandwidth
resources. This function ensures traffic isolation among these network planes and prevents
traffic congestion on one network plane from adversely affecting communication on other
network planes.
4.7 Distributed Virtual Switch
In the FusionSphere solution, each host is connected to a distributed virtual switch (DVS).
Such a DVS serves as a physical network switch to forward data among all hosts connected to
it and ensures that the VMs on these hosts have consistent network configurations after
migrating to other hosts.

4 Key Features
4.8 Virtual Storage Management
Storage virtualization helps the system better manage virtual infrastructure storage resources
with improved resource utilization and flexibility as well as increased application uptime.
FusionSphere supports various storage devices, including IP storage area network (IP SAN),
Fibre Channel storage area network (FC SAN), network-attached storage (NAS), and
FusionStorage.
4.9 Automatic Installation and Deployment
FusionSphere provides an automatic installation and deployment tool, which helps improve
the installation and deployment efficiency and avoid risks of system failures caused by
manual operations.
4.10 One-Click Upgrade and Patching
FusionSphere provides a one-click upgrade and patching tool, which reduces the system
maintenance workload and improves the maintenance efficiency.
4.11 Centralized Monitoring
FusionSphere provides a unified operation and maintenance (O&M) user interface (UI) to
implement centralized system monitoring and management. This unified UI provides the
following information:

All alarms generated in the system

All monitoring information about computing, storage, and network resources in the
system

Service scenario description and operation procedure guide
4.12 Multi-DC Management
FusionSphere uses the OpenStack cascading solution to support management of multiple data
centers. OpenStack cascading allows an OpenStack system to manage other OpenStack
systems and provide unified OpenStack application programming interfaces (APIs) for users
to manage multiple data centers.
The cascaded OpenStack systems can only use the FusionCompute hypervisor.
The OpenStack cascading solution has the following features:

Open architecture: FusionSphere provides standard northbound and southbound
OpenStack APIs to interconnect with other OpenStack-compliant components.

Reliable fault-isolated system: A single cascaded OpenStack system manages a
maximum of 1024 servers, limiting the server failure impact to a small scope. Even if the

FusionSphere
Solution Description (Cloud Data Center)
4 Key Features
cascading OpenStack system fails, the cascaded OpenStack systems can still manage
servers in the system.

Isolation during an upgrade: A single cascaded OpenStack system can be upgraded
without adversely affecting other systems, and different OpenStack versions can be used
in the same system. Upgrading a single OpenStack system will not lead to the upgrade of
the entire cloud environment that runs a million of VMs.

Horizontal expansion: FusionSphere enables expansion of both cascaded OpenStack
systems and servers in a single cascaded OpenStack system, allowing the entire
FusionSphere environment to host 10,000 servers and a million VMs.

About This Chapter

5.1 System Reliability
OpenStack HA
OpenStack reliability is determined by the reliability of the services provided by
FusionSphere OpenStack. FusionSphere OpenStack employs active/standby redundancy or
load balancing mode to ensure reliability of the services provided by its components.

Active/Standby redundancy mode: Generally, only the active node provides services.
The standby node provides only basic functions and periodically synchronizes data from
the active node. If the active node fails, one standby node takes over the services and
becomes the new active node, and the original active node changes into the standby one.

Load balancing mode: In normal cases, all nodes provide services at the same time. If
one node fails, services on this node are evenly distributed to other nodes that are
running properly, without interrupting services.
Data Consistency Audit
FusionSphere automatically audits and restores key resources. It also supports periodic audit
and manual audit of VMs, volumes, and images to ensure data and status consistency. When
detecting an exception, FusionSphere automatically generates an audit report and reports an
alarm. FusionSphere also provides maintenance instructions based on the audit report for the
maintenance personnel to make judgments and take recovery measures. This function ensures
consistency of various correlative data in the system and prevents residual resource data from
adversely affecting the system.
Management Data Backup and Restoration
FusionSphere periodically backs up configuration and service data on local and remote
devices. If any management node service fails and cannot be automatically restored,
FusionSphere allows users to rapidly restore the service using the local data backup. If a
catastrophic failure causes both the active and standby management nodes to become faulty

and not be restorable by a restart, FusionSphere allows users to restore these nodes using the
remote data backup, thereby shortening the service restoration duration.
Black Box
FusionSphere supports the black box function. After detecting a system exception, the black
box collects the fault information, saves the information in the non-volatile storage, and
notifies FusionSphere maintenance personnel of the exception. After restarting the system,
maintenance personnel can use interfaces to export exception information from the black box
to locate and rectify the fault.
