I have worked in the information technology field since 1998. I have designed, deployed, and maintained server, desktop, network, and storage systems. I provided all levels of support for businesses ranging from single-user through enterprises with thousands of seats. Along the way, I have achieved a number of Microsoft certifications and was a Microsoft Certified Trainer for four years. In 2010, I deployed a Hyper-V Server 2008 R2 system and began writing about my experiences. Since then, I have been writing regular blogs and contributing what I can to the Hyper-V community through forum participation and free scripts.

Hyper-V and PowerShell: Get Hyper-V VM MAC Address

Hyper-V and PowerShell: Get Hyper-V VM MAC Address

16 Dec by Eric Siron    0

While not common, there are times when you might need to know the MAC address for a virtual machine. This is a quick script to help you quickly retrieve that information. This article is part of the “Hyper-V and PowerShell” series. This script is meant to be as much a matter of teaching as functionality,…

Hyper-V and PowerShell: Get Hyper-V VM IP Addresses

Hyper-V and PowerShell: Get Hyper-V VM IP Addresses

11 Dec by Eric Siron    6

Retrieving a virtual machine’s IP addresses isn’t an especially difficult process, but it’s still something you might do often enough that it would be convenient to have a quicker way. For me, I don’t do it often, but I still like to have a single function. I’ve improved the one I use to make it…

Hyper-V and PowerShell: A Deep Dive into Get-VM

Hyper-V and PowerShell: A Deep Dive into Get-VM

09 Dec by Eric Siron    0

In the introductory article of this series, we talked about objects in PowerShell and how the large and grandiose uses of PowerShell are difficult to explain. While reflecting on that article, I realized that out of all the programming languages that I know, PowerShell’s verb-noun convention is probably the best way there is. This article will…

Monthly Round-Up: November 2014

04 Dec by Eric Siron    0

Our monthly commentary and link round-up for November 2014. Don’t Underestimate the Sniff Test If you read very much of what I write, you’ll know that I don’t put a lot of stock in fancy titles or credentials and I certainly pay little attention to self-anointed experts, regardless of how many popularity contests they’ve won….

Hyper-V and PowerShell: Part 1 of However Many It Takes

Hyper-V and PowerShell: Part 1 of However Many It Takes

25 Nov by Eric Siron    1

I, and a lot of other authors, have been cheerleading for PowerShell for quite some time. I think that a major problem with the most common approach is that it highlights all the wonderful things about PowerShell as a technology. I have my doubt that very many IT professionals decide to adopt new things based…

If you’ve had very much virtual machine churn in your environment, it’s almost inevitable that you’ve wound up with a few disconnected virtual machine files here and there. This free script will help you to locate orphaned Hyper-V VM files. For fellow infrastructure scripters, there is a special bonus script included as well. The worst…

Free Script: Gracefully Restart Virtual Machines on Hyper-V

Free Script: Gracefully Restart Virtual Machines on Hyper-V

18 Nov by Eric Siron    2

There is one function whose absence in all official Hyper-V tools is blatantly obvious, and that is the ability to gracefully restart virtual machines. A Restart-VM function was introduced in 2012, but it just hard stops the VM before turning it back on. I suppose it has uses, but I’ve never found a good one….

12 Common Hyper-V Deployment Mistakes

12 Common Hyper-V Deployment Mistakes

13 Nov by Eric Siron    3

I’ve seen a lot of questions from those who have recently deployed Hyper-V for the first time. Some just need a few pointers to iron some minor glitches, but some are in really bad shape. Here are some of the common deployment mistakes and their solutions. 1. Mis-Provisioning Resources in Hyper-V There are a lot…

Quorum in Microsoft Failover Clusters

Quorum in Microsoft Failover Clusters

06 Nov by Eric Siron    0

The topic of quorum in Microsoft Failover Clustering often gets very little mention. Quorum guides the actions of surviving nodes when there are system-level failures. This technology has evolved substantially over the last few versions of Windows/Hyper-V Server and many are not aware of the changes. The Purpose and Function of Quorum Quorum has one…

Monthly Round-Up: October 2014

04 Nov by Eric Siron    0

Our monthly commentary and link round-up for October 2014. Think in Tiers In the world of computer systems, you often see tiered designs. Software developers talk about “n-tier applications”, in which you have a “data layer” and a “business logic layer” and a “presentation layer” and whatever other layers make sense for that application. Storage…

Live Backup Changes in Hyper-V Server 2012 R2

Live Backup Changes in Hyper-V Server 2012 R2

29 Oct by Eric Siron    0

Quite some time ago, we wrote a post about taking live backups in Hyper-V. Hyper-V Server 2012 R2 really changed the mechanics of backup. This post examines how those changes have affected live, or hot, backups. Until 2012 R2, backup was strictly based on VSS (Volume Shadow Copy Service) operations. Backup applications trigger VSS in…

Choosing a Management OS for Hyper-V: Windows Server

Choosing a Management OS for Hyper-V: Windows Server

16 Oct by Eric Siron    5

In the sister article to this piece, we talked about choosing Hyper-V Server over Windows Server as the management operating system. In this one, we’re going to go down the other road and make the case for Windows Server instead. A Clear Definition of Hyper-V Terms The earlier article had a section devoted to clearing…

Choosing a Management OS for Hyper-V: Hyper-V Server

Choosing a Management OS for Hyper-V: Hyper-V Server

14 Oct by Eric Siron    2

For the server edition of Hyper-V, you have a choice in management operating systems. You can use the free, no-GUI Hyper-V Server or you can use the full-fledged Windows Server. This will be the first of two articles in which I will argue both sides of the debate. In this installment, I’ll take the position…

Hyper-V and Networking Part 8: Load-Balancing Algorithms

Hyper-V and Networking Part 8: Load-Balancing Algorithms

09 Oct by Eric Siron    2

We’ve had a long run of articles in this series that mostly looked at general networking technologies. Now we’re going to look at a technology that gets us closer to Hyper-V. Load-balancing algorithms are a feature of the network team, which can be used with any Windows Server installation, but is especially useful for balancing…
