A quick look at ESXi rollback

vmware_view_pilot-5132020Last week I went on a vSphere Fast Track [v6]. One of the most interesting things that I learned was that a rollback feature exists within ESXi, which has been around since ESXi 3.5. It may be handy in some specific scenario’s, like when you experience driver issues after an update from ESXi 5.5 to ESXi 6.0.

My ITIL Foundation exam experience

PowerShell Basics: PowerShell cmdlets

This is my second post that is part of blog series called PowerShell Basics.

Announcement Blog series: PowerShell Basics

PowerShellWindows PowerShell is a utility that has been around for quite some time. In computer sciences terms, Windows PowerShell may be called a shell, which is a user interface that gives you access to an operating system and the various services that it runs. A shell can be fully command-line based or it can include a graphical user interface (GUI). PowerShell by itself is an advanced command-line based environment, that eventually tends to fully replace the good old Windows command-line utility. Microsoft designed the tool to help administrators easily automate and resolve management tasks. However, mastering PowerShell’s automation to it’s full potential is not quite as easy as it seems.
