Kubernetes with Mixed CPU Architecture

Creating a Raspberry Pi Kubernetes cluster is straight forward, however it becomes more complicated when you want to mix and match kubernetes nodes of different CPU architectures.

Pipedrive and Zendesk Integration

If your Customer Service System and your Sales CRM are separated it is important to integrate the systems. Without a proper integration either your Sales or Customer Service team might be missing important informations. This free Pipedrive and Zendesk integration will help you solve this issue.

Datrium DVX 101 – Adding Hosts

After covering the NetShelf setup in Datrium DVX 101 – NetShelf Setup a few weeks back, it is time to cover the host setup.

In order to add an ESXi host to a Datrium DVX, it has to meet the following requirements:

  • ESXi 5.5 U2 or later
  • Minimum of 2 cores for the Datrium Hyperdriver
  • Minimum of 7.5 GiB memory for the Datrium Hyperdriver
    • ~2.5 GiB memory for each additional terabyte of flash
  • At least one 800 GB SSD or 2x 400 GB SSDs

The actual process of adding a host to the Datrium DVX is easy and only a few mouse-clicks away.

  1. Open the Datrium GUI within the vSphere Web-Client
  2. Browse to Hosts and Clusters and select the host you would like to set up
  3. Go to Monitor -> Datrium DVX and hit Install
