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.

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