vcloud director map vcloud automation center

How vCloud Director constructs map to vCloud Automation Center

By admin on September 30, 2013 in Cloud Computing

As most people know, I have been working with vCloud Director since its beta days. My mind thinks of cloud in easy bite site chunks of Virtual Data Centre and Organisations. I have now been spending a lot of my time and focus on vCloud Automation Center, but still always find myself thinking about the vCloud Director constructs and how they map over to vCloud Automation Center. In vCloud Director I have listed the most common constructs that are seen every day. Provider VDC Organisation VDC Organisation vApp Catalog vCenter Server Cluster or Resource Pool We all know and love these constructs, and know how they fit together. I created the diagram below to help me understand where I need to go in vCAC to create the same object. For example, if I wanted to essentially create an Organisation in vCloud Automation Center, where would I create this? The organisation […]

Affected by the Allocation Pool changes in VCD 5.1.x? Change it back

By admin on May 16, 2013 in Cloud Computing

Have you been affected by the Allocation Pool changes in VCD 5.1 when you upgraded? If you have been, and are looking for a way to make this allocation model the same as in VCD 1.5, VMware has included a feature in VCD 5.1.2 that allows you to change it back to the original way it was conceived. First lets look at the changes in the Allocation Pool. Massimo ReFerre has written a great article showing the differences between the two versions of the allocation model http://it20.info/2012/10/vcloud-director-5-1-1-changes-in-resource-entitlements/ In this article he provides a comparison chart for you to easily see the differences, and gives a nice review of allocation models at the end of the article. OK but what does all this mean for me? As I am sure you are more confused than when you started reading this post… perhaps it makes sense to put a stake in the ground […]

vCloud Director and SE Sparse Disks

By admin on April 2, 2013 in Cloud Computing

So the other day, a bunch of us were asked the question: “A customer of ours has asked if the partial writes issue with linked clones that was found in View and fixed in 5.2 with SE sparse disks has also been fixed in vCloud Director Fast Provisioning with SE sparse disks” Cormac Hogan wrote a really great article on SE Sparse Disks, which can be read by clicking here. This is possibly the most exciting new storage feature in the vSphere 5.1 release. Space Efficient Sparse Virtual Disks (or SE Sparse Disks for short) were designed to alleviate two issues. Let’s describe these issues first of all. Problem Statement #1 – Let’s take a Guest OS running on a linked clone (View desktop if you will), and this Guest OS issues a 4KB write. vmfsSparse disk (which is the format used by traditional linked clones) has a block allocation […]
