H3C Application-Driven Data Center (AD-DC) Solution is a data center solution based on SDN architecture. It accelerates deployment of network infrastructure, simplifies network operation and maintenance, and optimizes network with higher efficiency.
AD-DC solution adopts MP-BGP EVPN as control plane and VXLAN as data plane to build an overlay network. It decouples the business from the physical network. AD-DC solution integrates cloud platform, SDN network, and security to deliver a resilient, secure, visible and automated data center.
H3C Virtual Converged Framework (VCF) controller is a SDN-based controller for AD-DC solution. As one of the key components in the solution, VCF controller provides standard Restful API northbound interfaces for H3C CloudOS or third party cloud platform and southbound interface to manage network equipment. VCF controller provides centralized GUI-based network operation and management to customers.
AD-DC solution provides end-to-end automation from underlay and overlay network deployment to service provision that shortens the deployment time by almost 80%.
To perform underlay network deployment, customer only need to plan the network and configure automation parameters. The underlay network will be deployed automatically and the whole process is visible.
Regarding overlay network, VXLAN network establishment and table entries synchronization at Layer 2 and Layer 3 are worked out automatically. Provide comprehensive automated services of the tenant networks, security resources, VM deployment and the network connections to the cloud.
● Flexible Security Service
AD-DC solution supports north-south and east-west security protection. Virtualize security devices into a unified service chain resource pool to provide flexible service chain orchestration and granular security service for tenants. Each tenant can create their own security service instance independently.
● On-demand Security Protection
Unified management for network and virtualized security resources. Tenants can apply for virtualized security resources on demand and orchestrate traffic forwarding paths with service chains.
Unified fabric management and service orchestration for single or multi data centers. VCF controller manages network resources through southbound interfaces and integrated northbound Neutron plug-in to interoperate with OpenStack-based cloud platform, such as H3C CloudOS.
H3C CloudOS platform provides unified orchestration and O&M for network and compute resource.
● Agile Load Balance
Adopts ECMP to provide fast load balancing between spine and leaf devices in an underlay network, ensuring reliable transmission even if only one spine device is working. Support multi Border to achieve load balance at the egress of tenant networks to ensure high reliability.
● Controller Cluster
Supports maximum 128 controllers cluster. The master controller will be taken over by the other controllers in case of the master controller failure and make sure the constant service. The master controller takes charge of the management of the controller cluster.
● Controller Survivability
VCF controller provides centralized management for the network. Even if all VCF controller fail, the already running service will not be affected.
● Comprehensive Visibility
Comprehensive visibility from underlay network and overlay network to compute resource and network status, such as network prediction, historical data, log file, alert and heath score etc. It simplified network management and improve the maintenance efficiency.
● Intelligent Prediction
Support heath score and health status alarming for customers to understand the network conditions in real time. Detections of physical, virtual, and table entry resources and alarm thresholds can be customized. Radar ping and other troubleshooting methods are available to help customers to discover and locate faults in time.
● Cloud Platform
VCF controller not only interoperates with H3C CloudOS but also OpenStack-based third-party cloud platforms.
● OpenStack and Open API
Compatible with OpenStack Version K, L, M, O, P, V and standard restful API interface to integrate with third-party management system.
Three scenarios in AD-DC solution:
● Single Fabric.
● Multi Fabrics.
● Data Center Interconnection.
