Enterprises face many challenges as they move forward with digital transformation. Windows Server 2016 brings Software Defined Networking (SDN) to help solve these problems. SDN makes networks easier to manage and change, helping them keep up with new app needs. Microsoft Azure shows how well SDN works by making daily thousands of network changes. With SDN, companies can make their networks better, more reliable, and more flexible. This makes their data centers more agile and efficient.
Key Takeaways
- Windows Server 2016 introduces Software Defined Networking (SDN) to address modern data center challenges.
- SDN provides centralized configuration and management of networks and network services, enabling dynamic creation, securing, and connection of networks.
- SDN is key for running big data center networks well, as shown by Microsoft Azure’s daily network changes.
- SDN helps companies make their networks better, more reliable, and more flexible. This makes their data centers more agile and efficient.
- Onlive Server, a leading cloud hosting solution provider, uses SDN to offer its customers reliable, scalable, and flexible network services.
Understanding Software-Defined Networking Infrastructure
Software Defined Networking (SDN) is changing how data centers manage their networks. It uses three main parts: the Network Controller, the Software Load Balancer, and the Gateway.
Key Benefits for Modern Data centers
SDN brings many benefits to data centers, including:
- More flexibility and speed in managing the network
- Ability to grow with infrastructure needs
- Better security through central control and monitoring
- Lower costs and less complexity
Integration with Existing Networks
SDN is great at working with existing networks. It uses SDN-compatible devices to link virtual and physical networks better. This improves performance and visibility across the whole system.
| Component | Description |
| Network Controller | Provides centralized automation and management for virtual network infrastructure, utilizing Microsoft’s Service Fabric for high availability and scalability. |
| Software Load Balancer | Evenly distributes customer network traffic among multiple virtual machines, ensuring efficient resource utilization and optimal performance. |
| Gateway | Enables traffic routing between virtual and external networks, facilitating seamless connectivity between the virtual and physical infrastructure. |
Network Controller Deployment Requirements
Setting up the Network Controller in your data center needs careful planning. You must configure security groups and enable dynamic DNS registration. These steps are key for the Network Controller to work well.
The Network Controller should run on its virtual machines. It manages network services like virtual networks and subnets. It also handles micro-segmentation and Quality of Service (QoS) policies. You can use SDN Express Power Shell scripts or Windows Admin Center for deployment.
Network Controller Deployment Considerations
- The Network Controller server role should not be deployed on physical hosts but in dedicated VMs.
- High availability is key, so use at least three VMs for the Network Controller application.
- The Network Controller uses Service Fabric for high availability and scalability.
Network Controller Features
- Virtual network management: Supports VLAN-based networks, NVGRE, and VXLAN.
- Firewall management: Configures allow/deny firewall Access Control rules for workload VMs.
- Software Load Balancer: Enables load balancing, inbound NAT, and outbound access to the Internet.
- Gateway management: Supports various types of gateway connectivity using VPN and Layer 3 forwarding.
- Virtual appliance chaining: Attaches virtual network appliances for advanced services.
API Interfaces
The Network Controller offers Southbound and Northbound APIs. These APIs manage network devices, services, and communication with management apps.
Deployment Flexibility
The Network Controller can be set up in different environments. This includes on-premises and cloud platforms like Onlive Server. It offers flexibility for network management.
Physical Network Prerequisites and Hardware Specifications
Setting up a strong software-defined networking (SDN) in your data center needs careful thought. Windows Server 2016 and its SDN features need specific hardware setups for the best performance and reliability.
Network Adapter Configurations
Each physical compute host in your data center needs one or more network adapters. Make sure they’re set up right, like NIC teaming and RDMA support, for the best performance and reliability.
Logical Network Configuration and Planning
A well-thought-out logical network plan is key to build a strong and growing software-defined networking (SDN) setup. Windows Server 2016 has great tools for managing and tweaking VIP logical networks. This makes it easy to fit into your current network setup.
Public VIP Network Setup
The public VIP network is for outside users to access your services. It uses IP addresses that can be routed. This network is a safe, easy way for people to access your cloud services and apps.
When setting up the public VIP network, pick IP address ranges and VLANs wisely. Make sure they don’t clash with your current network. This ensures everything works smoothly together.
Private VIP Network Implementation
The private VIP network is for inside use only. It doesn’t need to be seen by the outside world. This keeps your important data and apps safe from harm.
Choose the right IP addresses and VLAN IDs to set up the private VIP network. This makes it easy to work with your Windows Server setup.
GRE VIP Network Configuration
The GRE VIP network helps connect different places, like offices or branches. It uses GRE tunnels for safe, reliable links. This way, data moves well between your virtual and real networks.
Getting these network parts right is vital for a good SDN setup. You can make your network better by matching VIP logical networks, IP subnet prefixes, and VLAN IDs with your Windows Server setup. This leads to a fast, scalable solution for your business.
Gateway Solutions for Virtual Network Connectivity
Windows Server SDN gateways connect virtual and physical networks. They create secure IPsec connections between SDN networks and external networks over the internet. For non-encrypted links, GRE connections make connecting SDN networks to external ones easy.
The Layer 3 connectivity option lets SDN gateways act as routers. This helps virtual and physical network components in a data center talk to each other. They use Border Gateway Protocol (BGP) to find and share routes, making manual router setup less needed.
High Availability and Scalability
SDN gateways are set up in high-availability pools with M+N redundancy. This means “M” active VMs are backed by “N” standby ones. This setup keeps the network running even if a gateway fails.
Gateway pools can grow or shrink by adding or removing VMs. This lets organizations adjust to changing needs without service disruptions. Each gateway has its own Layer 3 connections and VLAN mappings, keeping different virtual networks separate.
Versatile Deployment Options
SDN gateways in Cheap Windows Server work in Azure Local instances. This makes it easy for cloud service providers to manage many tenants in their data centers. It helps integrate with existing infrastructure and manage virtual network connections smoothly.
