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.

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).

In a previous post I've talked about issues in the StoragePolicy and Tag cmdlets in PowerCLI. I found a workaround by ignoring certificate warnings and setting my date format to en-US. Today I tried to replicate some Storage Policies from one vCenter to another and I found that I got new errors... I can export the …

Following up on my last post on Automating DRS Groups with PowerCLI I found that we also need to automatically remove VMs and Hosts from a given DRS Group. Although I could have included this in the previous script which creates the groups and adds members I wanted to separate them. There could for instance be times …
