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. As data flows from the guest VMs and into the network, the Ethernet frames are encapsulated. I've written previously about the value of overlay networking, but the following are the key points to note about VMware's approach: Networks Agents as Software Controller-Based Networking Next page: Software Defined Data Centers 1 of 2.

VMware Training and Certification: Studying for the VCP5 exam. Even though the VCP5 exam is only 5 weeks old at the time of writing, there are some amazing resources already available to help with those preparing for the exam. I've always been an advocate of trying to prepare yourself using the official resources that VMware make available - the exam blueprint tells you what aspects of vSphere 5 you will get tested on, the exam format, number of questions, time limit, and the scoring system.
The exam blueprint makes references to the official vSphere 5 documentation, which VMware validate the exam items against, and the mock exam gives a decent indication of the exam format. The VCP community forum is an excellent way of asking VCP5-related questions and getting furter information.

By Massimo, on April 17th, 2012 There have been a lot of discussions lately about SDN (Software Defined Networking). Arguably SDN may mean a lot of different things to a lot of different people. If you ask the like of Facebook, Google and academic researchers they will probably tell you that SDN is all about gaining full visibility (and control) on how packets flow on the network. People and organizations that are closer to the commercial world may tell you that SDN is all about creating an abstraction layer (virtualization anyone?) In the network – from layer 2 all the way to layer 7. I’d like to focus on the latter definition of SDN.
A few weeks ago Cisco’s Lauren Cooney asked a question on twitter on the line of “how would you define SDN?”. Look at the picture. SDN purists may very well argue that this PDF was not including important aspects of SDN such as self-service capabilities and a proper API to access these functionalities. Massimo. 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 Regardless, virtual machines provide a way to simulate multiple computers and I’ve done 3-tier software testing (client to app server using WCF and app server to SQL 2005 backend) to verify our framework can support both 2-tier (client –> DB) and 3-tier deployments. Rarely used it for development, again due to speed. . Now, nothing wrong with running the VM within VMWare, but I always find that it is a bit sluggish unless I go to full screen mode. . VMware vSphere 5 Host NIC Network Design Layout and vSwitch Configuration [Major Update] | Tech Blog | Blog.
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. The assumption of these physical NIC designs is that these hosts are going to be configured with Enterprise Plus Licensing so all the vSphere features can be used. They key to any design is discovering requirements.

Rackmount servers have the same compute potential as blade servers but you also get a greater failure domain. Depending on the amount of VMs your host can hold, should be an indicator of 1GB vs 10GB.

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. Introduction to Virtual Networking in VMware Workstation It’s the virtual network, as created by VMware Workstation, which connects your virtual machines to the physical network.

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). For new users who are seeking a thorough explanation of how VMware ESX networking functions, I’ll recommend a series of articles by Ken Cline titled The Great vSwitch Debate. Ken goes into a great level of detail. Go read that, then you can come back here. Before I get started it’s important to understand that, for the most part, the information in this article applies only to VMware ESX. The majority of all the networking configuration you will need to perform on VMware ESX boils down to just a couple commands: To create a vSwitch, use this command: VMware ESX network redundancy via Fibre Channel multipathing. VMware ESX has built-in support for Fibre Channel multipathing, which enables network redundancy.
VMware vCenter Server comes in two versions: Standard and Foundation. vCenter Server performs the following three key functions: How to Install VMware Workstation and Create a Virtual Machine on Your PC. Edit Article Two Parts:Install VMware WorkstationAdd Virtual MachinesCommunity Q&A VMware Workstation is a computer emulator. It allows you to create virtual machines in which you can install operating systems as if they were physical machines. You might want to emulate an operating system because you want to run a program that isn't compatible with the host operating system (the operating system that you are installing VMware Workstation on), or because you want to test malware without putting an actual computer at risk. This article shows you how to install VMware Workstation 11 and create or open a virtual machine.

To help you get a better understanding and expand your knowledge of virtualization, get to know these useful terms and how they apply to virtualization and its process: Bare metal: Virtualized servers in which the virtualization software is installed directly on the machine rather than on an operating system. Because it installs on the machine, it is said to reside on “bare metal.” Client virtualization: Using virtualization to enable a client device (like a laptop) to support isolated operating environments. Client virtualization is often used to move workloads into isolated environments to reduce system administration requirements. P2V: Shorthand for “physical to virtual.”
P2V stands for the process of migrating systems from the physical hardware they originally ran on to virtual operating environments running in a virtualized environment. Storage virtualization: Using shared storage located on individual servers so that multiple servers can share a single storage device. Introduction to Virtualization.
