Backup Space

N/A

When using the backup function, the storage quota occupied by the tenant needs to provide the corresponding storage quota when applying for the tenant quota or when the administrator allocates the quota.

CDP

Continuous Data Protection

Continuous data protection is an advanced backup technology at the IO second level, which can record every data change and optimally achieve RPO=1s to protect data. Sangfor Cloud Platform adopts optimized CDP technology and provides customers with low-cost, easy-to-deploy, and high-value data protection solutions using the CDP module at the file layer.

Super Administrator

The super administrator (also known as the admin user) has all the operation and operation and maintenance management permissions. It is the role with the most permissions in the multi-tenant model of the entire Sangfor cloud platform.

DRS

Distributed Resource Scheduler

Dynamic resource scheduling technology. Sangfor Cloud Platform continuously and dynamically balances resources through the introduced automation mechanism, migrates virtual machines to hosts with more available resources, ensures that each virtual machine can call corresponding resources in a timely manner, and guarantees business systems performance.

Allocation

N/A

Platform administrators can assign virtual machines in the administrator's root directory to corresponding virtual machine groups or tenants, and tenants can also allocate virtual machines under their directories to corresponding virtual machine groups or tenant sub-accounts.

HA

High Available

A high-availability cluster usually requires two or more nodes to form a cluster. When an accident occurs on the node where the virtual machine with the HA function is enabled (the host is powered off, the network is disconnected, etc.) Select a node with sufficient resources to automatically restart the virtual machine to achieve uninterrupted or short business interruption. Sangfor cloud platform provides high-availability node services. When an abnormality is found, and the duration reaches the fault detection sensitivity set by the customer (for example, 5 minutes), the HA virtual machine will be switched to run on another node.

Deallocate

N/A

The platform administrator can deallocate the virtual machine whose permissions belong to the tenant to the administrator's root directory, and the tenant loses the use permission of the corresponding virtual machine. Tenants can also reclaim virtual machine corresponding to tenant sub-accounts.

Recycle Bin

N/A

It temporarily stores the deleted platform administrators, tenants, and other VM resources, network resources, and backup resources. In addition, the deleted resources can be recycled.

Work Order

N/A

The multi-tenant, self-service IaaS service provided by Sangfor Cloud Platform is a brand-new infrastructure delivery and usage model, which can abstract IT physical resources into elastic virtual resource pools provided on demand, including virtual machine, storage, network, Network security, providing external services in the form of consumer units (i.e., tenants or virtual data centers) and providing users with these consumer units and other infrastructure including virtual machine and operating system images through fully automated self-service access Schema and application service templates.

Cluster

N/A

The physical hosts with the HCI virtualization software installed are uniformly added to a management platform for maintenance, which is convenient for business deployment and can also improve the effective utilization of resources. Generally, it is used in conjunction with virtual storage. Sangfor cloud platform can add multiple clusters to perform unified resource management in the form of resource pools.

Role

N/A

Sangfor cloud platform built-in user types, different roles have different permissions and functions. The platform preset roles are divided into admin, tenant, and tenant user.

Image

N/A

An elastic server template that includes software and necessary configuration, at least the operating system, and can also include application software (such as database software, development tools, etc.) and proprietary software. Sangfor SCP images can be divided into Public VM Images, Private VM Images, and Network Device Images.

Clone

N/A

Generate an identical virtual machine through cloning to improve business deployment efficiency.

Snapshot

N/A

The status record of a certain moment of data storage, Sangfor cloud platform records the status of qcow2 at the snapshot moment by taking a snapshot of qcow2, that is, the data location described by the qcow2 file at that time. The data recovery of the virtual machine can be performed through the snapshot at this moment.

Template

N/A

Take a current virtual machine as the main body, convert it into a template (shutdown and locked state), and then derive N virtual machines consistent with the current template status. The image file of the derived virtual machine refers to the template image file and its incremental image and can configure the data disk.

NFV

Network Function Virtualization

Network function virtualization. Sangfor cloud platform realizes various network function resources required in the network through NFV, allocates and flexibly schedules on demand to realize network function virtualization in cloud architecture.

Quota

N/A

The usage and allocation of basic resources (computing, network, storage resources) and NFV resources in the Sangfor cloud platform. Tenants can apply to the administrator to use related resources. Administrators can also learn about the resource usage of the entire cloud platform through quota usage.

Direct line

N/A

The virtual machine in the VPC needs to communicate with the tenant's local data center under the cloud or the equipment hosted in the equipment room. Two different parts of the network.

SCP

Sangfor Cloud Platform

Sangfor cloud computing platform is the general term for the entire cloud platform management architecture.

Private Image Repository

N/A

The storage quota occupied by cloud platform tenants for uploading images or creating images needs to be provided when applying for tenant quotas or when assigning quotas by administrators.

Elastic IP

N/A

For the IP addresses that can be accessed outside the Sangfor cloud platform, you can bind the elastic IP to the corresponding virtual machine in the tenant or the VPC egress router to access resources outside the VPC.

VPC

Virtual Private Cloud

For the IP addresses that can be accessed outside the Sangfor cloud platform, you can bind the elastic IP to the corresponding virtual machine in the tenant or the VPC egress router to access resources outside the VPC.

VXLAN

Virtual Extensible LAN

A network virtualization technology. An extension of VLAN technology can penetrate the third-layer network to expand the second layer. The central two-tier virtual migration and multi-tenancy requirements.

Tenant

N/A

The tenant administrator has the management rights of all resources and tenant sub-accounts in the tenant and is the second-level management role in the Sangfor multi-tenancy model.

Tenant User

N/A

Tenant users have administrative rights to the virtual machine resources associated with them. The tenant user is the third-level role in Sangfor's multi-tenancy model.

Resource Pool

N/A

The collection of cluster resources on the Sangfor cloud platform can associate clusters that have been added to the cloud platform to different resource pools, manage resource pool resources through the cloud platform, and allocate resources to tenants for use.

Resource Reservation

N/A

Reserve a certain resource space on some nodes. The system or other virtual machines will not use this part of the resources. When a node fails or is switched for disaster recovery, the reserved node resources can immediately restore the virtual machine, reducing the risk of business failure recovery due to insufficient resources. Risk of failback failure.

Create Image

N/A

The platform administrator can select a virtual machine configured according to requirements and use it as a template to create an image. The image created by this method will retain all the software and data of the virtual machine system disk.
