VCAP-CIA objective 3.3 – Manage Organization VDCs

September 9th, 2013 Leave a comment Go to comments

The blueprint states the following skills needed to cover this objective.

  • Configure storage tiers
  • Create, manage and delete org VDCs

As I already covered how to add more storage to a Provider VDC we will concentrate on how to change attached storage profiles for a Organization VDC. As every Organization can consist of several Organization VDCs you will be able to assign different storage profiles, which need to be pre-existent in your vSphere environment, to these VDCs so that your Dev&Test VDC is not eating up all your precious space and performance for your production workloads.

The assigning process can be done either directly during the creation process of an Organization VDC which will be described in the second part of this post or at any later stage by opening the Organization VDC and choosing the “Storage Profiles” tab.

In the same menu you can also disable a storage profile, delete it, change the default profile to be used or changing the size limit for the Organization VDC in the properties option.

Fast provisioning and thin provisioning settings can also be changed after creation an Organization VDC using the “Manage & Monitor” tab and right clicking the Organization VDC choosing the “Properties” option.

The second goal of this objective is to create, manage and delete Organization VDCs.  The process is described as well in the following kb article and in the English version of the vCloud Director Administrator’s Guide on pages 32 – 40.

As Organization VDCs are created using a specific allocation model with different use cases for each model some more information can be found using the following resources.

So let’s start by creating one. This can be done by choosing option 6 on the quick start page.

orgvdc1

You will then need to choose an organization and a Provider VDC to host the Organization VDC.

orgvdc3

The next step is to choose an appropriate allocation model.

orgvdc4

You then will be able to configure the resource settings, limits and reservation for CPU, memory and the maximum number of VMs that can be deployed in that Organization VDC. This screen differs a bit between the different allocation models. You will only be able to choose a specific vCPU speed in the PAYG model and you won’t be able to set any reservations in the Reservation Pool model. There will also be a rough estimation on how many VMs this Organization VDC will be able to host scaled in 3 different VM instances; “small”, “medium” and “large”.

orgvdc6

orgvdc7

Next up will be the storage configuration. Here you can add the storage profiles and thereby the datastores available to the Organization VDC as well as setting the default instantiation storage profile. An upper limit on how much space can be used for each storage profile can be configured as well. You can also choose the options for thin and fast provisioning in this screen.

orgvdc8

This leaves the network pools to set. You will be able to choose 1 network pool from which the vApp networks will be created. If you already pre-configured a vShield Edge device in that network pool you will see a list of all the configured services that Edge device offers.

orgvdc9

On the next screen you will be able to choose if you want to deploy a new Edge device and also configure it on the spot even though you may choose to do the configuration part later as well. Advanced settings like IP settings, IP Pools and rate limits can also be configured on the spot.

orgvdc10

If you choose to deploy an Edge Gateway you will need to select the external networks that gateway can provide access to.

orgvdc11

If needed you can create a routed organization network and also share it across the whole organization.

orgvdc12

The last step will be to name and enable the organization VDC.

orgvdc13

The different options for managing the Organization VDC are described on page 52 – 63 in the English version of the vCloud Administrator’s Guide.

These include the following tasks:

  • Enable or disable an Organization VDC
  • Delete an Organization VDC
  • Add a storage profile to an Organization VDC
  • Modify the Organization VDC name and description
  • Edit the Allocation Model settings
  • Edit storage settings
  • Edit network settings

All these tasks can be done by using the “Manage & Monitor” tab. To enable or disable the VDC just right click on it and choose the according option. You can also delete the VDC this way as long as it is disabled and all vApps, Templates and media was deleted or removed as well.

orgvdc14

The process to add a storage profile to the Oganization VDC was described in the beginning of this post.

To change the name and description of the VDC select the “Properties” option when right clicking the VDC and choose the “General” tab.

orgvdc15

You will not be able to change the actual allocation model for an Organization VDC but you can change the settings of the current model, e.g. the CPU reservation by selecting the “Allocation” tab.

orgvdc16

If you want to enable or disable thin and fast provisioning you will need to select the “Storage” tab.

orgvdc17

The “Network Pool & Services” tab will let you change the network pool backing the Organization VDC as well as the actual number of networks provisioned for this VDC.
