vCloud Automation Center – vCAC 6.0 – Enabling Catalog Items

When we created a blueprint we had to publish the blueprint. Publishing the blueprint allows it to become available as a catalog item that we can assign to a service and later entitle a user to have access to. In this article we will be assigning the blueprint to a service and enabling it as a catalog item. This will not make it show up in the catalog just yet, but creates a relationship between the blueprint and the service for which it will be published under.

vCloud Automation Center – vCAC 6.0 – Creating a Service

vCAC 6.0 introduces us to a new Self-Service catalog and a new way of managing Catalog Items. In previous versions of vCAC Blueprints were assigned to groups within the Blueprint itself. In vCAC 6.0 Blueprints are published which enables them to be assigned to users and groups through the catalog management components of the vCAC Service Catalog.

To enable blueprints to be available in the catalog we first need a service that we can publish them to. A service is really just a container that will hold the object. If you look at the service catalog you can see the services listed down the left side. These services are the containers that hold the actual catalog items that can be requested.

We must have at least one service in the environment to enable our catalog items against. Below are the steps to create a service.

vCloud Automation Center – vCAC 6.0 Creating a Physical HP Blueprint

Physical blueprints are a bit different than Virtual Blueprints because you can’t give users the ability to define the exact makeup of the machine they want. They can’t decide they want to add additional storage to a physical machine like they can a virtual. They also can’t select which network they want the machine placed on (without customization) like a virtual machine.

What they can do however is tell you how many CPU’s and how much RAM they would like in the physical machine they are requesting. I know what do you mean they can tell me what they want? vCAC can’t magically add CPU’s or memory, but what it can do is look for a match, or the closest match to what they user needs. You have the ability to set a maximum and minimum number of CPU’s and amount of RAM a user can request from the blueprint. You can also determine how you want to allocate for each of them. You can have vCAC look for an exact match to the request, or look for an “At Least” match to find a server that meets the needs of the request.

* This tutorial is meant to show you the basics of creating a Physical HP server blueprint. I will be publishing a number of more complete physical provisioning tutorials and this article will be utilized as a reference.

vCloud Automation Center – vCAC 6.0 Creating a VCHS Reservation

VCHS reservations are very similar to creating a vSphere reservation as you may expect. You are going to assign it to a Tenant and business group, you are going to reserve memory and storage, and determine what networks are available just like you would do when creating a vSphere reservation. There is really on one minor difference. You don’t have to manage and maintain the underlying hardware. In my mind that is a huge plus.

Creating a VCHS reservation

  1. Start by going to Infrastructure -> Reservations -> Reservations and from the “New Reservations” menu select Cloud and then vApp(vCloud Director).

vCloud Automation Center – vCAC 6.0 Creating a vSphere Reservation

There are two types of vSphere reservation within vCAC. Reservations against a vSphere host and reservations against vSphere clusters. In order to create either a vCenter server is required. To make a reservation against a vSphere host it cannot be part of a vSphere cluster. Unlike physical reservations when creating a vSphere reservation you do not need to consume the entire vSphere host or Cluster in one reservation. You can create multiple reservations against a vSphere resoruce consuming parts of it in each reservation. You also have the ability to over subscribe the vSphere host or cluster.

When creating a vsphere reservation you have the ability to reserve memory, storage, and determine what networks are available within the reservation. vSphere reservation also give you the ability to determine how workloads can consume the resources. This is achieved in a number of ways. The first of which is a reservation priority. The reservation priority allows you some control over how you consume your resources. Let’s say you have two reservations assigned to a business group. If you wanted workloads to fully consume one before being placed against the other you would give the different priorities. The one you would want to fill first would be say a priority of 1,and the other would be a priority of 2. If you want to fill them equally you would give them the same priority. This will cause vCAC to round robin the placement of the workloads.

You can also implement the same types of placement priority for datastores within the reservation using the priorities you associate to each datastore.
