SDN with SCVMM

You can use Virtual Machine Manager (VMM) to manage your physical and virtualized network infrastructure. In VMM, the foundations of the network configuration are networks—the underlying logical networks and the VM networks—and switches. Switches can be configured as standard virtual switches, but this set of topics describes logical switches, which help you configure switch settings consistently across multiple hosts. To configure these network elements in VMM, use the following overviews and procedures :

Configuring logical networks, VM networks, and logical switches in SCVMM

You can use Virtual Machine Manager (VMM) to manage your physical and virtualized network infrastructure. Logical networks form the foundation of your network configuration in VMM. You create and name logical networks based on the function they serve in your environment, for example, the “Management,” “Cluster,” “Storage,” or “Tenant” networks. Within each logical network, you create one or more network sites that specify IP subnets, virtual local area networks (VLANs), or subnet/VLAN pairs that represent your environment.

In a logical network, you can provide static IP addressing by creating static IP address pools for the logical network. Dynamic Host Configuration Protocol (DHCP) is also an option.

plan logical networks, network sites, and IP address pools in VMM by doing the following :

  • Plan your logical networks, network sites, and IP address pools
  • Logical networks created by default
  • Guidelines for network sites: VLAN and IP subnet settings
  • Guidelines for IP address pools

VM Network

VM networks for VLAN configuration

In Virtual Machine Manager (VMM), after you complete the planning described in Overview: plan logical networks, network sites, and IP address pools in VMM, you can plan your VM networks. Use this table for more information:

Purpose of VM network Description
For VLANs: see Plan VM networks for a VLAN-based configuration in this topic You can use familiar virtual local area network (VLAN) technology for network isolation, and manage your configuration in VMM.
For Hyper-V network virtualization: see Plan VM networks for Hyper-V network virtualization in this topic You can support multiple tenants (also called clients or customers) with their own networks, isolated from the networks of others, by using VM networks configured for network virtualization.
Direct access to the logical network (“no isolation”): described in this table A VM network can provide direct access to a logical network. No planning is needed, other than to identify the logical network to give access to. This is the type of VM network typically used for management networks (for example, the network used for managing a host).

Logical Switch

Logical Switch

In Virtual Machine Manager (VMM), you can use logical switches (and the port profiles inside them) to help you configure switch settings consistently across multiple hosts. A logical switch is like a template for a virtual switch—it acts as a container for the switch settings and capabilities that you want to use. Instead of configuring switch settings individually for each network adapter, you can specify settings and capabilities in a logical switch, and then use the logical switch to apply those settings consistently across network adapters on multiple hosts.
