UCS Video: Service profiles creation

Continuing with the Unified Computing System posts I wanted to touch on the concept of Service Profiles in UCS. Service Profiles is a logical construct that makes the UCS stateless. In other words, servers are logical entities that reside in a hardware platform. These logical servers can be associated and dissociated from the physical hardware with the click of a mouse. With them, you can replace, provision, and enable a server in a matter of minutes.

Quoting the configuration guide: "Each service profile serves a specific purpose: ensuring that the associated server hardware has the configuration required to support the applications it will host. The service profile maintains configuration information about the server hardware, interfaces, fabric connectivity, and server and network identity. This information is stored in a format that you can manage through Cisco UCS Manager. All service profiles are centrally managed and stored in a database on the Fabric Interconnect."

Some important characteristics of Service Profiles:

  • It is a self-contained definition of server and connectivity configuration and identity.
  • It applies to compute resource via direct association or via pools.
  • It can be migrated with no local dependencies.
  • It can be created into a template and it can be cloned.
  • One server can host one and only one service profile at a time.
  • After you associate a service profile with a server, the server is ready to have an OS and applications.

The exact and official configuration guide can be found here

I tried to create a smooth illustrative video of how to configure Service Profile and apply them to hardware. Here's my attempt at that (my excuses in advance for the going back and forth in the video):
