Virtual Networking 101: Understanding VMware Networking

Virtual Networking 101: Understanding VMware Networking
May 30, 2012By Petra Jorgenson On a basic, structural level, virtual networks in VMware aren’t that different from physical networks; vSphere is designed to mimic the functions of a physical network, so a lot of the network hardware you’ll find in the real world, you’ll find virtualized in VMware. If you understand how physical networks operate, then understanding virtual networking shouldn’t be too difficult. Before jumping into an explanation of how VMware handles virtual networking, I’ll first provide a quick refresher of the basic equipment that makes up a physical network. If you already have a firm understanding of how networking works, then you can skip the following paragraph. To connect to a network, a computer must be network-capable, meaning that it must have a working network interface controller (NIC), also known as a network card or network adapter, installed. In VMware, switches are used to establish a connection between the virtual network and the physical network.

Using VMware: Understanding the Virtual Switch Introduction In this article we will explore the VMware ‘Virtual Switch’. The Virtual Switch is nothing more than a logical switching fabric built into your VMware infrastructure (ESX) so that you can network your Virtual Machines (VMs) however you need them.

Understanding Virtual Networking in VMware Workstation 9 Introduction In my opinion, VMware Workstation is the premier and ideal platform for virtualizing desktops on your local Windows or Linux laptop or desktop computer. This is because Workstation offers the most maturity and functionality out of any of the desktop-based hypervisors. Workstation has a strong snapshot manager, the greatest list of supported guest operating systems, remote virtual machine management/control with the new WSX (see my article – Managing VMware Workstation VMs Remotely with WSX), connectivity to vSphere in the datacenter for VM management and import/export and, finally, the most mature virtual networking. What I’ll be focusing on in this article is how virtual networking works in VMware Workstation and what’s new related to virtual networking in Workstation version 9.

VMware NSX: Game Changer for Data Center Networks VMware's network virtualization product, NSX, may upend data center networks the same way the hypervisor changed servers. Now that VMware has conquered data center computing via server virtualization, the company is opening a beachhead on the network via its NSX product, which is being officially launched today at VMworld in San Francisco. VMware NSX is a software-defined network (SDN) that uses controllers and overlay networking. I'll examine just a few of the key aspects of the announcement and how they apply to your data center strategy. Overlay networking refers to the use of protocols such as VXLAN and STT to create a virtual network between hypervisors. VMware vSphere Storage Appliance (VSA) for Shared Storage End of Availability VMware is announcing the End of Availability of all vSphere Storage Appliance versions, effective April 1, 2014. After this date you will no longer be able to purchase this product. All support and maintenance for vSphere Storage Appliance 5.5 will be unaffected and will continue to follow the Enterprise Infrastructure Support Policy. The End of General Support life date for customers with vSphere Storage Appliance 5.5 remains September 19, 2018.

Connect to VMWare virtual machines using Remote Desktop Had a short training on VMWare on Tuesday, the software development department finally got the official permission (read: get a license) to use VMWare Workstation. I’m no stranger to Virtual Machines (VMs) – started playing with Virtual PC 2005 a fwe years back and I understood the general concepts of hardware virtualization. The biggest problem I have with VMs in general is the slowness; I’d rather develop directly on my PC, which is faster. Can’t say I’ve delved deep into it, but I know enough to utilize it and be dangerous Configuring a Virtual Network Features | Documentation | Knowledge Base | Discussion Forums Prev Contents Last Next The first topics in this section give you a quick look at the virtual networking components that VMware Workstation provides and show how you can use them with your virtual machine. The rest of the section provides more detail on some networking capabilities and specialized configurations.

VMware vSphere 5 Host NIC Network Design Layout and vSwitch Configuration [Major Update] This is an update to an older post and I wanted to overhaul it for the Indy VMUG... This was also another VMworld submission that didn't get the votes. See what you guys are missing out on? :) As vSphere has progressed, my current 6, 10, and 12 NIC designs have slowly depreciated. In an effort to update these to VMware vSphere 5, I took the 2 most popular configurations of 6 and 10 NICs and updated the Visios to make them a bit more pretty. New User’s Guide to Configuring VMware ESX Networking via CLI 23 June 2009 A lot of the content on this site is oriented toward VMware ESX/ESXi users who have a pretty fair amount of experience. As I was working with some customers today, though, I realized that there really isn’t much content on this site for new users. That’s about to change. As the first in a series of posts, here’s some new user information on creating vSwitches and port groups in VMware ESX using the command-line interface (CLI).

Virtual Blocks For those of you have been following this thread for a while, you know we’re in the midst of head-to-head performance testing on two identical clusters: one running VSAN, the other running Nutanix. Recently, we’ve updated the Nutanix cluster to vSphere 6 and 4.1.3 — however, no differences have been observed performance since the change. Up to now, we’ve only been able to share our VSAN results.
