The vExpert program is not a technical certification. VMware states: The judges selected people who were particularly** engaged with their community and …

When trying to upgrade our lab vcenter from 6.5 to 6.7 this week we encountered a strange error. Our lab environement is running vSphere 6.5 on VCSA and we are running with an external PSC. So when starting the upgrade of the PSC I got an error early in the process, while connecting to the source VCSA. Error when …

Following up on my last post on Limiting disk i/o in vSphere we will now see how to automate this. First off we need some way to identify what limit a specific disk should have. You can do this in multiple ways, you could use an external source, you can use Tags or as we've done, Storage Policies. All our VMs and VMDKs …

This will be a post following on the previous one on how to control disk i/o in vSphere That post showed how you set IOPS limits either through the UI or with PowerCLI. Even though you set the limit on individual disks you need to work through the VM. And when you retrieve the disk limits for a VM you'll get back …

As a Service provider we need to have some way of limiting individual VMs from utilizing too much of our shared resources. When it comes to CPU and Memory this is rarely an issue as we try to not over-committing these resources, at least not the Memory. For CPU we closely monitor counters like CPU Ready and Latency to …

This blog post will be building on a previous post where I built a small PXE server environment for ESXi installation. In this post we will enhance the PXE install with customized kickstart files specific for the hardware we want to install. There's two new components to discuss here. The kickstart file (ks.cfg) it …

I had the privilege of delivering 3 sessions at VMUG Norway this week in Oslo, Trondheim and Bergen. With the extremely nice weather in Norway this week in mind the attendance were great and as always the discussions were valuable. My session on vSphere Performance monitoring were the short version of the blog series I …

I'll be speaking at VMUG Norway's meetings this May. As always there will be "three sessions in three cities". Oslo, May 29th Trondheim, May 30th Bergen, May 31st The topic for my session will be how we have built our own vSphere Performance monitoring solution which I've also done a blog series about. The VMUG …

In my blog series on building a solution for monitoring vSphere Performance we have scripts for pulling VM and Host performance. I did some changes to those recently, mainly by adding some more metrics for instance for VDI hosts. This post will be about how we included our VSAN environments to the performance …

In our environment we run ESXi primarily on HPE Proliant servers. We use OneView for managing the hardware it self (i.e. monitoring, firmware), but for provisioning ESXi to the servers we have been doing some of it manually and some of it with HPE Insight Control Server Provisioning (ICsp). When preparing for …
