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.

vCloud Automation Center – vCAC 6.0 Creating a Physical HP Reservation

Physical reservations are different in nature than a virtual reservation. Unlike virtual reservations we cannot dynamically assign Memory, CPU, Disks, or network adapters. We are stuck with what is in the physical machine. When we talk about self-service and automation it poses an interesting problem. How do we allow users to request a physical server that meets their needs.

The Physical Reservations combined with Physical Blueprints in vCAC help us solve this problem. In this article we are talking about Physical HP servers, and if we had a rack loaded full of servers it’s highly probable they wouldn’t be exactly the same. That’s fine we can add as many physical servers of varying configurations as we need to a reservation in vCAC. A physical Hp server reservation in vCAC is simply a collection of Physical HP servers managed through their iLo interfaces.

If you have reviewed Adding Physical HP iLo EndPoints you would have noticed that every physical server requires an endpoint. Once the endpoint is created vCAC does a discovery and learns about the physical specs of the server. A resource is then created for that server that can be added to a physical reservation.

vCloud Automation Center – vCAC 6.0 – Creating a Business Group

Business Groups are representations of your organizations logical groupings of users and managers. These can be business units or other groupings such as developers, windows users, etc. Business groups are very important within vCAC because these are the groups that you assign resources to. You can assign resources from the various types of supported infrastructure to these groups and the users are then able to provision workloads to those assigned resources.

Creating a Business Group

  1. From the Infrastructure menu select Group form the left menu.

vCloud Automation Center – Active Directory Computer Account Management Extension

Overview

A common extension requested for vCloud Automation Center is the ability to pre-create computer account objects in Active Directory in a specific Organizational Unit, and also to decommission the accounts in different ways along with the virtual machine. Without a custom workflow, you can have the computer join the domain during the customization phase, but this will only create the computer account in the default Computers container. Also, while there is an out-of-the box AD machine cleanup plugin which can be enabled, it will likely never support the multi-tenancy introduced in vCAC 6.0. vCO does not support it today either, but it is more likely to gain support in the near future.

This solution implements these functions using vCenter Orchestrator and its plugins for vCAC and Active Directory.

The rest of this article contains instructions on installing and configuring the vCAC AD Computer Account Management Extension. This extension allows administrators to model very specific OU structures for their AD machine accounts using vCAC custom properties, and supports dynamic OU Distinguished Name building based on combinations of properties derived from different areas of vCAC (compute resources, reservations, groups, blueprints, etc.).

This extension is Continue reading “vCloud Automation Center – Active Directory Computer Account Management Extension”

vCloud Automation Center – vCAC 5.2/6.0 – Custom Hostnaming Extension v3.1

Overview

One of the most frequent asks when using vCAC is, “How do I deploy machines using my company’s hostnaming standards automatically using vCAC?”  Since the out-of-the box hostnaming only provides a way to do prefix-suffix, the answer to this question usually is that it will require customization.

This solution is intended to provide a way to implement this functionality by using a small, highly versatile custom extension which can handle 95% of use cases without writing custom code.

The rest of this article contains instructions on installing and configuring the vCAC Custom Hostnaming Extension.  This extension allows administrators to model very specific custom hostnaming schemes for their vCAC virtual machines, multi-machine services, and vCloud Director vApps using vCAC custom properties, with dynamic creation of stock machine prefixes and index tracking for each unique hostname combination.

This extension is Continue reading “vCloud Automation Center – vCAC 5.2/6.0 – Custom Hostnaming Extension v3.1”

vCloud Automation Center – vCAC 6.0 – Creating a Fabric Group

Fabric groups are important in vCAC.  The Fabric groups are what enable you to provide access to resources from your physical infrastructure.  Within a fabric group you add users or groups that are responsible for managing infrastructure resources and add the resources they are responsible for.  For example you may select clusters that are managed from vCenter and assign the user/groups that are responsible for managing those resources.

Creating a Fabric Group

  1. From the Infrastructure menu select Group form the left menu.
