SCVMM 2012 review - Part 3: Logical networks, storage integration

In this part we see how Systems Center Virtual Machine Manager 2012 will make it a LOT easier to manage networks with new automation features, how it integrates with hardware load balancers and SAN storage.

One hassle in Systems Center Virtual Machine Manager 2008 and Hyper-V today is the restriction of having to manage networks on a per NIC basis; SCVMM comes to the rescue with new networking features.


Logical networks in Systems Center Virtual Machine Manager 2012
A logical network with one or more logical network definitions groups together IP subnets and VLANs to simplify network management in SCVMM 2012. Typical networks would be backend, frontend, management or backup. When you provision a host or VM you associate it with a logical network and it automatically receives a fixed IP address and mac address. Logical networks can span geographies with one or more logical network definitions for each location. You can also use DHCP instead of controlling IP address allocation through SCVMM if you so desire. Each NIC on a host needs to be associated with a logical network in either trunk or access mode. In the latter only a single VLAN ID is allowed whereas in trunk mode multiple VLAN IDs can be used in different VMs that share the NIC.
