VMware vCloud Director 101 – Concepts – Part 2

By admin on March 1, 2012 in Cloud Computing, Featured

This is part 2 of the VMware vCloud Director 101 blog posts I am writing. In Part 1 I explained some of the basic principles of vCloud director, this can be read by clicking here. Within Part 2 and Part 3 we are going to discuss the concepts and constructs within vCloud Director. This will cover definitions you may already have heard of, like Virtual Data Centers (vDCs) or Allocation Models. Part 3 will discuss vCloud Director Allocation Models, and then Part 4 will talk about Networking Concepts. (These really do need articles all by themselves). What is a vCloud? vCloud Director itself does not constitute a vCloud. A vCloud is made up of a number of components including vCloud Director. I have written a number of articles in the past discussing the vCloud Eco-System and its components and how they fit together from a design and integration perspective. For the […]

VMware vCloud Director 101 – Overview – Part 1

By admin on February 29, 2012 in Cloud Computing, Featured

Quite a few people have been asking me to write this article for a while. vCloud Director has been around a while now, but it appears that it is only now gathering momentum and it is being looked at seriously. This multi-part article will cover all the basic concepts of vCloud Director and what the different terminology means. First of all, lets talk about what VMware vCloud Directors actual purpose is: A quote from the VMware vCloud Director page on VMware.com explains: Manage resources more efficiently by logically pooling infrastructure capacity into policy-based virtual datacenters. VMware vCloud Director integrates with existing VMware vSphere deployments and extends capabilities like Distributed Resource Scheduler (DRS) and vNetwork Distributed Switch, to provide elastic compute, storage and networking interfaces across multiple clusters. Using virtual datacenters built on top of vSphere, VMware vCloud Director enable resources to be provisioned without the need for repeated configuration or significant maintenance. The […]

vCloud Director PAY-AS-GO vCPU default setting – Gotcha

By admin on February 23, 2012 in Cloud Computing

During Partner Exchange I had quite a few discussions with people about the default vCPU setting when creating an Org vDC with a Pay-As-You-Go allocation model. Now this is nothing new however this is still causing quite a few performance issues out in the field. When creating a new Org vDC through the wizard, after selecting the allocation model Pay-As-You-Go, you are shown the configure window. This window allows configure the compute requirements for this Org vDC. This is where the gotcha comes in. The default setting vCPU is configured at 0.26 Ghz. I will repeat this as I know I have missed it in the past. The default setting for vCPU is 0.26GHz. You can see in the screenshot below the default setting. So how does this actually relate to the objects in vCenter? By leaving this set to the default, this will configure every VM you create with a […]

Screen flicker in VMware Fusion 4.x

By admin on February 22, 2012 in General, MAC OS X

Lately I have been having issues with the screen in my VM running under Fusion flickering. This is particularly annoying when working in Visio and trying to draw up a diagram. It is not good for the eyes 🙂 The below screenshot shows the issue I have been experiencing: To stop the flicker enter the VM settings and turn off 3D Acceleration under the Display configuration. You will need to Power off the VM before you can make this change. Once the VM is powered on the screen will no longer flicker, therefore saving your eyesight 🙂
