Cisco UCS Resource Pools - 642-999 DCUCI Study Guide

When it comes to certification exams, part of the process is going through the blueprint provided by Cisco and making a best guess at where to focus your time. Cisco provides a percentage to give an idea of where to focus your time. These notes fall into section four of the 642-999 Exam Blueprint - Provision Cisco UCS Compute Resources.

[alert-announce]This post is another in my series about the 642-999 DCUCI CCNP Data Center exam. It is not intended to be an all encompassing post, however a collection of the notes I have gathered during my studies. [/alert-announce]

Resource Pools

Resource pools come in two different flavors - physical pools and virtual pools. Physical pools are hardware related (a Server Pool for example), while virtual pools contain information. Virtual Pool examples include UUID Pools, MAC Pools, WWNN pools.

Server Pools

Server pools fall into the physical resource pool category. There are two types of server pools - server pools and dynamic server pools. A dynamic server pool allows hardware to join the pool based on a specified set of criteria, which is defined in the server pool qualification policy (more on this in a bit).

Create a Server Pool

To create a server pool we follow through the Server Pool Wizard located on the Servers Tab -> Pools -> Server Pools -> Click the Plus button. A server pool requires the following information:

  • Name
  • Description (optional, though strongly suggested)

After that screen, we add actual hardware to the pool. If we are creating a dynamic server pool, do not choose any hardware, just finish the wizard.

Create a Dynamic Server Pool

To create a dynamic server pool, we must first create an empty server pool. After that is completed, create a Server Pool Policy Qualification Policy. This is done from Servers Tab -> Policies -> Server Pool Policy Qualification -> Click the Plus button

This wizard will allow you to specify any criteria for the server pool. Things like processor type, number of cores, RAM amount or speed, etc are all selectable fields.

Once the that policy is created, a Server Pool Policy must be created. This policy ties your Server Pool Policy Qualification to the Server Pool created above.

Virtual Pools

Virtual pools give us the ability to create pools of MAC Addresses, WWNNs, and UUIDs that will be provisioned to our blade servers.

The UUID pool is created by going to the Servers Tab -> Pools -> UUID Suffix Pool -> Click the Plus button

From here we have several things to consider. The UUID is a 128 bit serial number, of which 64 bits are a derived prefix created by UCS. The 64bit suffix can be customized to specification. When creating the pool, it is best to leave room for growth. If you have 100 servers now, make the pool 150 in size.

MAC pools are created in the LAN tab, WWNN pools are created in the SAN tab. Similar to the UUID pool, we define our own addresses based on specifications.


Resource pools are a core part of the UCS system. By creating dynamic server pools, we can automate hardware allocation, and with virtual pools we can automate the deployment of vUUIDs, vMAC Addresses, and vWWNNs. These pools will eventually be tied to a Service Profile, to further automate deployment.
