Nutanix at VMworld 2014

VMworld 2014 is the first VMworld as Nutanix employee. For me is something very new as Nutanix is well known as innovative company and its very well-recognized by attendees. First things first Nutanix at VMworld 2014 – Software YES !! Nutanix is a software company. Not hardware, not storage – like some people says (yes, we do replace legacy SAN storage) but software. On VMworld 2014 in US, Nutanix announced Cloud...

The ultimate VM batch deployment script.

The ultimate VM batch deployment script.

In my first blog post ever, almost three months ago I shared my good ol’ script for batch deployment of virtual machines.

PowerCLI report on storage paths (mis)configuration.

After drifting away into some niche topics in my previous post, I’m back to my “hobby@work” – PowerCLI scripting! Anybody who ever worked with block storage (so FC or iSCSI) sooner or later came across the task of “managing” storage path configuration in the environment.

Auto Deploy – bulk licensing and Authentication Proxy.

There are great many resources on vSphere Auto Deploy you can find on the Web. Artur wrote about it more than a year ago, I can also recommend step-by-step tutorial on Wojciech’s blog. In this post I would like to share my experience about two topics that are in fact fine-tuning of your Auto Deploy and make the whole deployment process almost completely “hands-off” (that’s a good thing!). 1.     First – bulk...

vSphere Web client and high DPI displays

I bought brand new DELL XPS 15 with High DPI screen – 3200 x 1800. Obviously, daily work with this resolution without changing size for icons and fonts and other items,would not be possible on a long distance :-). When I finished initial configuration of Dell XPS 15 I downloaded latest patches for Windows 8.1 – after few reboots laptop was ready to work. All apps works just fine and displays content correctly: web browsers...

PowerCLI script to report and change host NTP settings

The script I would like to share today is in a way supplementary to what I wrote about in my previous post. For those who don’t know it yet – last week I gave an example of completely turning off VMware Tools guest time synchronization via script that is able to set any of virtual machine “advanced settings”. Now I would like to look at subject of timekeeping from vSphere host perspective, I think we all agree...
