In the FusionSphere OpenStack environment, Nova provides lifecycle management for compute instances. On-demand response includes VM creation, scheduling, and reclamation.

Cinder provides persistent block storage for running instances. Its pluggable drives facilitate block storage device creation and management.

Keystone provides monitoring and measurement for FusionSphere OpenStack charging, baseline, scalability, and statistics.

Horizon provides a web-based self-service portal which interacts with FusionSphere OpenStack underlying services, such as starting an instance, allocating IP addresses, and configuring access control.

The group management of computing nodes classifies computing nodes with the same configuration policy to the same device group.

eSight detects and limits the resource usage of different computing nodes, ensuring the resource uniqueness.

A computing node can belong to either a device set or a device group.

A group can be associated with multiple group profiles. The member profile of a computing node is generated based on the group profile.

The computing resource scheduling automation technology can determine whether to migrate a VM based on the CPU usage, memory usage, or both the CPU and memory usage.

In power management, hosts can be powered on or powered off manually or automatically.

The VM migration rules include the keep-VMs-together, mutually-exclusive-VM, and the VM-to-host-group rules.

The IMC policy supports only live migration of Intel CPU series. CPUs from other vendors can be configured with this policy.

Cinder provides block storage to be attached to VMs to provide additional disk space for VMs.

Swift is used to store VM images.

In the FusionSphere environment, Glance backend storage is the Swift object storage by default.

In the FusionCompute environment, block storage contains only SAN storage and local storage.

Most of the cyber security systems cannot identify the traffic of the encrypted VMs.

Communication between VMs in a server is not perceived by physical security devices.

VM images use the tools that can enable communication between VMs to bypass firewalls.

The client operating system can activate the secret mode.

Services are migrated from traditional data centers to cloud data centers.

Traditional data centers are taken over by cloud data centers after being cloudified.

Services are migrated from the existing cloud data centers to other cloud data centers.

Services are migrated from cloud data centers to traditional data centers.

To create a snapshot, the current disk is set to read-only. The system automatically creates an incremental disk in the data store where the disk locates.

An incremental disk records the differences between the current state of the disk and the state of the disk in the last snapshot.

Multiple snapshots can be created for one VM. If a VM is being restored using a snapshot, other snapshots of the VM are not affected.

Snapshots can be automatically deleted.
