Why DRS Should Run Rules are better than anti-affinity rules in small clusters

The Distributed Resource Scheduler (DRS) allows vSphere Administrators to use rules to enforce virtual machine placement on cluster nodes. An example of such a rule is in the image below with a rule to reparate two domain controllers so that they won't run on the same vSphere host.

DRS Anti Affinity Rule

Configure Permissions for vRealize Orchestrator with AD

vRealize Orchestrator allows you to configure permissions for users in your authentication domain to access your vRO deployment with different types of access. While you might want administrators to access your workflows from the vSphere Web Client sometimes there will still be users that need access with the vRO client. One example is a group of developers that you only want to allow access to one or just a few folders in your vRO environment.

VCAP6 Deployment Exam Interface Tips & Tricks

Are you planning to take one of the four available VMware Certified Advanced Professional Deployment Exams? Then I suggest that you access the following web page and familiarize yourself with how the exam interface works. This prevents you from losing precious time during the exam. Dave Davis has done a very good job demonstrating how the interface works.

Configure Syslog server for NSX Controller with HTTP REST and vRealize Orchestrator

For many NSX components you can easily configure a syslog server, such as vRealize Log Insight. This however is not simple and straightforward for the NSX Controller Nodes. For those components this setting has to be configured via the NSX API via HTTP REST. In this article I explain how to use vRealize Orchestrator to accomplish this task.

The syntax and procedure are described in two locations:

vCenter 6.5 Appliance Backup and Restore

With the release of vSphere 6.5 VMware has introduced a new method for creating a backup of the vCenter Appliance. This method is available from the vCenter Appliance web management interface on port 5480 (https://applianceaddress:5480). In this article I will explain how to create a backup and what the restore procedure is.

Running VMware vSphere 6 vCenter Appliance on Ravello Systems

Running the VMware vSphere 6 vCenter Appliance on the Ravello Systems cloud is not supported in its native format. If you have created a local working copy of the appliance then you can import it into the Ravello Systems cloud environment. When you then want to Edit and Verify the imported virtual machine an error message will be generated that Ravello Systems only supports 7 virtual disks but the appliance was created by VMware with 11 virtual disks.

In this image you can see disks 10 and 11 of the imported appliance:

OVA/OVF Import tips for Ravello Systems

Bottom line of this article: use .OVF format for your VMs

When importing OVA's from my local system to Ravello Systems I ran into an error. Which was strange because I had imported similar machines just a few days before. The error message was the following: 

Referenced disk/s do not exist:
'[u'/var/folders/yv/g8hl5r3n6518yf3w6d95kbj00000gn/T/tmpQ_Z7y8ravello/vSphere6-ICM-v2-ESXi01-disk1.vmdk']s'

vRealize Automation 7 External Approval Policy with vRealize Orchestrator Workflow

With vRealize Automation 7 an Approval Policy can be linked to an event subscription that in turn can trigger a vRealize Orchestator workflow to perform an external approval process. In this article I describe how to setup the Workflow, the Approval Policy and the Event Subscription.

Workflow as downloadable package

Workflow to use for vRO Cluster Demonstrations

This simple workflow can be used to demonstrate the failover behavior in case of a vRealize Orchestrator node failure. It creates the number of VMs that your specify. I suggest 30. During the execution of the workflow power off one node of the cluster and you will be able to demonstrate that the execution continues on another node.

The workflow is available as a downloadable package:

com.vmwarebits.clustertest.zip

Process a text file from a Resource Element through an Array

This example workflow shows how you can use a ResourceElement containing a list of virtual machine names and execute a workflow for each of the VMs in the list. The workflows and actions are available as a package here: com.vmwarebits.vmlistExample.zip.

To use the workflow yoi create a ResourceElement and import a text file that contains the virtual machine names, such as in the next image.

Preparing SQL Server Express for a vRealize Automation 7 Proof of Concept Setup

For a vRealize Automation 7 deployment including Infrastructure As A Service (IAAS) a Microsoft SQL database server is a requirement. Not everyone has access to that software and when setting up a Proof of Concept environment it is not always justifiable to purchase a SQL Server license. Therefor in the case of a PoC it's a viable solution to use SQL Express.
