Windows Server 2012: An opportunity for customers to take advantage of VM Mobility and Multi-tenancy

NEC has been working closely with Microsoft to make full use of the Windows Server 2012 Hyper-V Extensible Switch to integrate and deliver an OpenFlow-based Software Defined Network. Some particularly impressive use-cases around automation, multi-tenancy, VM mobility, and security will be rolling out in conjunction with this new capability. This blog post looks at two of these.
ProgrammableFlow Fabric defines multi-tenant virtual networks in which tenants are isolated at the network level. With true traffic isolation between tenants, end systems belonging to one tenant network cannot reach end systems belonging to another tenant network. At the same time, each tenant can define its own customized layer-2 or layer-3 network and utilize inter-tenant isolation to effectively create a secured slice of the underlying physical network.
“ProgrammableFlow Network Suite unifies the physical and virtual network policy, creating the perfect complement to the Software-Defined Networking capabilities built into Windows Server 2012,” Microsoft’s Sandeep Singhal, General Manager, Windows Networking, tells us. "Built for the cloud, Windows Server 2012 Hyper-V provides rich multi-tenancy and isolation capabilities. The Hyper-V Extensible Switch enables NEC’s ProgrammableFlow Suite to provide an unified, end-to-end experience that is fully integrated into Windows.”
Windows Server 2012 Hyper-V Use Case 1: VM Mobility and consistent policy over Virtual & Physical Networks
Before September and the availability of Windows Server 2012, you had to configure your policy multiple times for both physical and virtual networks. In addition, if you wanted to move a virtual machine, it would typically require a network administrator to make those programming adjustments on the network. This is a time-consuming, expensive process, and often served as a bottleneck to your business.
In the new world of Windows Server 2012 and ProgrammableFlow® Networking, such moves and changes will be transparent, negating the programming requirement exists today —Valuable technical resources can focus on service delivery rather than configuration management. As VMs move, they will be instantly recognized by the OpenFlow-based ProgrammableFlow controller and the network topology will be automatically updated. And this is the really cool part: Using the extension provided by Windows Server 2012, NEC converts the Hyper-V Extensible Switch into an OpenFlow enabled virtual ProgrammableFlow switch. Enabling OpenFlow enables end to end network visibility and control. When you input your business policy into Windows Server 2012, ProgrammableFlow is able to read that policy and apply it – over both the virtual and the physical network.
With these capabilities, Windows 2012 Server users can roll out new applications, or make changes to your business priorities. Windows Server 2012 and ProgrammableFlow will be there to support you.
Windows Server 2012 Hyper-V Use Case 2: Granular Security Policy Administration
A second use case addresses the increased sprawl of network appliances. Using the flow control capabilities of ProgrammableFlow, network operators can redirect selected traffic flows into network appliances programmatically only as needed. The result is fewer firewalls are required. Even better, ProgrammableFlow works in tandem with Microsoft’s Hyper-V Network Virtualization to create a comprehensive Software-Defined Networking solution.
Faster processing. Fewer bottlenecks. More efficient use of resources. Granular policy administration and prioritization of your network traffic are hallmarks of ProgrammableFlow networking. We look forward to delivering it to you.
