To build upon my recent post for virtualization networking, Harold Wong, explains the details behind NIC Teaming, as well as some PowerShell cmdlets on the subject. Take a look here:
Virtualization Experts Series continues with Live Storage Migration explained by Brian Lewis. This step by step article shows the how, why, and what of moving virtual machine disks from one physical location to another, and the Powershell command is thrown in as well for you scripters out there. Take a look:

It seems that Yung Chou not only helps mentor IT Pros around the world, but 5th graders too? There is no stopping this guy. I bet his kids do their homework on Azure VMs as well! Great stuff take a look:
Our blog series on virtualization has gotten off to a good start. For today’s article we discuss network virtualization in Windows Server 2012 Hyper-V. For the basics, virtual machines need to be presented with a network port in order to gain access to the physical network. Since the host has a small number of physical network adapters the hypervisor(Hyper-V) needs to split up the network traffic on to virtual network switches. These virtual switches contain virtual ports, and the virtual ports show up in each virtual machine for which they are assigned as a traditional network adapter. The diagram below Read more
Here’s a little snippet from the great article Keith Mayer just published in the series:
New-IscsiTargetPortal –TargetPortalAddress <IP_Address or FQDN of storage array>
$target = Get-IscsiTarget
Connect-IscsiTarget –NodeAddress $target.NodeAddress“ Read more here:
Virtualization Experts Series – Part 4 arrives today. I originally wrote this article in answer to many requests during my Pro Camp events, but felt it needed added to our series this month.
During my Pro Camp events I often get asked about Hyper-V “Datastores,” in that VMware administrators want to know how to access them, search through the contents, and move files around. Since Hyper-V doesn’t really use the term “Datastores” I will often take a tangent at this point in the conversation to discuss the differences, as well as point out some of the similarities.
So for sake of this article I will use the term “Datastores” rather loosely. Datastores hold not only the virtual disk files that a VM utilizes as virtual hard drives, but also the configuration file for the virtual machine itself(in VMware: the VMX file). Sometimes the configuration files are held on different datastores than the virtual hard drives(in VMware: the VMDK files). So there are definitely occasions where the disk files and config file may not reside Read more
Dan Stolts brings us the latest installment in our series where he breaks down the importance of dynamic memory, and then compares it to the way that other Hypervisors might perform similar functions.
His comments on ballooning I don’t necessarily agree with fully(except for from a security perspective which I think was his main point). Ballooning maybe ok in some cases where you have tremendous disk speed but disk speed comes at a high premium and is not a resource I like to allocate toward something that could be fixed with proper configuration of the virtual environment. All in all, just stay away from paging, ballooning, and swapping if at all possible or you will eventually find yourself at the bad end of help desk ticket. I wrote an article on the topic some time ago, which can be found here:
In this article I show the questions we should be asking ourselves or our VMware admins. Part II gets into the next steps of the process.
Kevin Remde discusses the topic of Hot-Add in Hyper-V in today’s server virtualization blog series article. This is a great reference for those looking to get certified as well, since the article quickly identifies what can be added to a running VM in Hyper-V, as well as what cannot be added and why. Give it a read here:
Hosted by CITPG as the biggest IT Pro community event every year in the Charlotte area, this year promises to be bigger and better than ever. We will have presentations from some of the nation’s top technology professionals (MVP’s and Microsoft Evangelists) on a variety of topics ranging from What’s New in Windows 8, Windows Server 2012, and System Center 2012 SP1 and a hands-on lab will catch and hold your attention while providing you with the very latest in information related to the hottest topics in the IT world today!
Special presentations will be offered by:
Mark Minasi, Rhonda Layfield, Amy Babinchak, Jim Christopher, Larry Struckmeyer and Kevin Royalty, just to name a few. I will be hosting the hands-on-lab breakout where you will be able to deploy your own lab in the cloud. A full day of learning, collaborating, and networking. You don’t want to miss it!

It’s March already??? Our new series is kicking off and this month we dig into server virtualization. The first installment details out what all is coming this month. As always, if you would like to contribute to one of these articles or have any tips you would like to share please give us a shout, it’s all about sharing information folks. Now without further delay, here is the first post in the series:
