As IT Pros we’re often told to “Be flexible” and to “Do more with less”. Nothing is more true than when we’re talking about hardware, software licensing and the placement of network-critical services. While I agree with the above phrases, and Hyper-V allows us to do both with relative ease, there are still some guidelines [...]
Hyper-V Network Virtualization technology, sometimes referred as HNV, is primarily designed to be used by the hosting providers, but every SMB should know the benefits offered by HNV.
Did your software vendor indicate that you can virtualize their application, but only if you dedicate one or more CPU cores to it? Not clear on what happens when you assign CPUs to a virtual machine? You are far from alone.
With the responses to our article series on virtualized domain controllers, it seemed natural to tackle another related topic. Unfortunately, it’s a little too common for administrators to try to solve the physical vs. virtual dilemma by installing the domain controller role and the Hyper-V role in the same physical instance of Windows Serer. This [...]
In the first part of this series, we looked at the myths that scare people away from virtualizing their domain controllers. In this installment, you’ll see some of the ways that domain controllers can be successfully virtualized.
Using domain controllers in a virtual environment is a contentious and confusing issue. I’m going to start this subject by saying that there is no single correct answer. No one piece of advice is going to work for everyone in every environment. The purpose of this article series is to explain the facts so that [...]
In Part 1 and Part 2 of this article series, we focused on the various conditions which might cause Hyper-V Replication to fail. In the final part of this article series, we’ll tackle the remaining issues I’ve listed which may cause issues in Hyper-V replication.
Starting with Windows Server 2012 R2, it is possible to re-size a Virtual Hard Disk for a running Virtual Machine on Hyper-V! It was not possible to do so before for an online Virtual Machine running on Windows Server 2012 and earlier Hyper-V versions. Let’s have a look at some of the benefits this feature offers and [...]
In the previous parts of this series, our focus was on the basic concepts and theory involved with storage. With this installment, we’ll look at some of the ways you can approach your own storage challenges.
In Part 1 of this series, we learned about the different possibilities which may cause communication issues between Primary and Replica Server. In this part, we continue to focus on other possibilities and also explain a mechanism which can be used to rule out network port or firewall issues.
Now that Hyper-V Server 2012 R2 is finally available to all, the very big question of “should we upgrade” is on a lot of people’s minds. Some will tell you it’s a “no-brainer” and that you should just do it unquestioningly. In the real world of business, the true “no-brainer” decision is a very rare [...]
Ever wonder why your virtual machines report that their network speed is 10 Gbps, even if you haven’t got a 10 Gbps adapter in the physical box? If so, you’re certainly not alone. Knowing why depends on an understanding of the Hyper-V virtual switch.
Troubleshooting issues with the Hyper-V Replica requires extensive knowledge of the technology. Not only you need to have knowledge but you must also be able to follow a troubleshooting approach which helps you fix the issues and also benefits in finding the root cause. This is what I intend to explain throughout the articles of [...]
