PowerShell Compare-Hash Function

Quite some time ago I created a PowerShell function which allowed one to compare a given cryptographic hash against one locally generated to see if they match.

Set Cluster Log Size and Verbosity in Microsoft Server 2008 R2

Recently a critical cluster system had a bit of a hiccup wherein the SQL resource failed between nodes a few times and then gave up. Most of my clusters run on Microsoft Server 2012 R2 so I tend to use PowerShell for everything, in this case the cluster is an older one running Server 2008 … Read moreSet Cluster Log Size and Verbosity in Microsoft Server 2008 R2

Why I’m Using VMware ESXi In My Home Lab

A question came to me recently concerning my use of VMware ESXi on my home lab servers rather than Microsoft Hyper-V. I should of course acknowledge there are other options such as Linux and various other hypervisors but let’s stay on point for now.
