 Data planeIntroduction

In Part I of this series, we created the tenant virtual network and connecting two VMs to it using System Center Virtual Machine Manager, and then we validated that both VMs can route between each other.

In Part II, we created a public Virtual IP Address (VIP) on the Software Load Balancer (SLB) using VMM console and PowerShell through which we were able to access a website on the virtual network. We also created Site-to-site (S2S) VPN to a Remote site.

Introduction

In Part I of this series, we created the tenant virtual network and connecting two VMs to it using System Center Virtual Machine Manager, and then we validated they can route between each other.

In this blog post Part II, we will be creating a public Virtual IP Address (VIP) on the Software Load Balancer (SLB) MUX using SCVMM and PowerShell through which you can access a website on your virtual network. We will also create Site-to-site (S2S) VPN to a Remote site.

Please make sure to check Part I so you can have an overview of the infrastructure and the VMM Logical Network that we are using throughout this series.

Introduction

Software Defined Networking (SDN) in Windows Server 2016 provides a method to centrally configure and manage physical and virtual network devices such as routers, switches, load balancers and gateways in your datacenter. Virtual network elements such as Hyper-V Virtual Switch, Hyper-V Network Virtualization, and RAS Gateway are designed to be integral elements of your SDN infrastructure.

Please note that you must install Windows Server 2016 Datacenter edition for Hyper-V hosts and virtual machines (VMs) that run SDN infrastructure servers, such as Network Controller and Software Load Balancing nodes. However, you can run Windows Server 2016 Standard edition for Hyper-V hosts that contain only tenant workload virtual machines that are connected to SDN-controlled networks.

Software Defined Networking (SDN) Stack in the Windows Server 2016
Posted by Oksana Zybinskaya on November 3, 2016
5/5 (2)

Windows Server 2016 enables building a Software-Defined Data Center (SDDC) with new layers of security and Azure-related approach for hosting business applications and infrastructure. The new Software Defined Network (SDN) Stack  provides dynamic security and hybrid flexibility by enforcing network policy in the Hyper-V Virtual Switch using the Azure Virtual Filtering Platform (VFP) Switch Extension. Instead of programming network configurations into a physical switch,  the new Microsoft Network Controller delivers the network policy to the Hyper-V Hosts using the OVSDB protocol and is programmed into the VFP extension of the vSwitch by a Host Agent which enforces the policy.

You got SDN, now what

It has three years since VMware announced and showcased NSX to the world. Since then everyone and then some has announced their version of SDN. You have players such a Cisco, Cumulus Networks and of course VMware in this space. All doing SDN in their own unique way. Cisco being the biggest network player of course wants to move hardware to your datacenter. Therefore, their way to SDN is to buy new boxes. Another player is Cumulus Networks, again theirs another focus. Here the OS is king. Build on open source components Cumulus Networks deliver the OS for SDN, which run on any white box. If you do not want to build your own white box networks based on Cumulus Networks many vendors have, join Cumulus Networks. Vendors such as HPE, Dell and Supermicro amongst others are selling switches, which comes with Cumulus Networks OS baked in. Even Microsoft is entering the stage of SDN with Server 2016, though one could argue a bit late, but then better late than never.

How to Deploy Switch Embedded Teaming (SET) Using SCVMM 2016?

Windows Server 2016 - Switch Embedded Teaming with RDMA       Windows Server 2016 – Switch Embedded Teaming with RDMA [image credit: Microsoft]

Introduction

With the release of Windows Server 2016, Microsoft is introducing a new type of teaming approach called Switch Embedded Teaming (SET) which is a virtualization aware, how is that different from NIC Teaming (LBFO), the first part it is embedded into the Hyper-V virtual switch, that means a couple of things, the first one you don’t have any team interfaces anymore, you won’t be able to build anything extra on top of it, you can’t set property on the team because it’s part of the virtual switch, you set all the properties directly on the vSwitch. This is targeted to support Software Defined Networking (SDN) switch capabilities, it’s not a general purpose use everywhere teaming solution that NIC Teaming was intended to be. So this is specifically integrated with Packet Direct, Converged RDMA vNIC and SDN-QoS. It’s only supported when using the SDN-Extension.

HYPER-CONVERGENCE TAKES HOLD

Hyper-converged infrastructure, when we started to hear about it last year, was simply an “appliantization” of the architecture and technology of software-defined storage (SDS) technology running in concert with server virtualization technology. Appliantization means that the gear peddler was doing the heavy lift of pre-integrating server and storage hardware with hypervisor and SDS hardware so that the resulting kit would be pretty much plug-and-play.

Hyper-Converged Needs to Get Beyond the Hype
Posted by Jon Toigo on January 25, 2016
4.29/5 (7)

It used to be that, when you bought a server with a NIC card and some internal or direct attached storage, it was simply called a server. If it had some tiered storage – different media with different performance characteristics and different capacities – and some intelligence for moving data across “tiers,” we called it an “enterprise server”. If the server and storage kit were clustered, we called it a high availability enterprise server. Over the past year, though, we have gone through a collective terminology refresh.

Today, you cobble together a server with some software-defined storage software, a hypervisor, and some internal or external flash and/or disk and the result is called “hyper-converged infrastructure.” Given the lack of consistency in what people mean when they say “hyper-converged,” we may be talking about any collection of gear and software that a vendor has “pre-integrated” before marking up the kit and selling it for a huge profit. Having recently requested information from so-called hyper-converged infrastructure vendors, I was amazed at some of the inquiries I received from would-be participants.
