Introduction
It was typical to use the derived values (burned−in values) for UUID and adapter identities when you
deployed (installed, booted, or accessed) the Cisco Unified Computing System (UCS) Blade with the
Rack−Mounted (traditional server) paradigm. In the full Logical Server paradigm deployment, you need to
have identities defined with the logical service profile that will then be applied to the Cisco UCS blade. A
Logical Server is defined with identity (UUID, MAC/WWN addresses, and VLAN/VSAN requirements). The
profile can be associated with only one blade at a time, but the association can be changed if there is a
problem with a particular blade, or hardware maintenance is required on a particular blade.
The Mobile (Relocatable) Logical Server concept allows the same logical server to be booted on different
blades at different times. When a blade is associated with a server profile, it inherits all its identity and boot
information from the profile. This model works best when the OS is booted off a SAN LUN. This document
shows you how to create pools of identity information defined within the Logical Server Profile to facilitate
the Mobile Logical Server concept:
Create UUID Pools
• 
Create MAC Pools
• 
Create WWN Pools
• 
Once these pools are created, it simplifies blade management within the Cisco UCS environment.
The Cisco UCS leverages itself to a model where server farms can be easily allocated and deployed, without
the need to pre−associate specific hardware to specific server roles. Server pools lend themselves to the server
farm model. Note that you still need a separate logical server profile for each server that is booted
simultaneously. If you want to deploy a farm of 50 web servers, you need 50 separate (but hopefully very
similar) profiles. This Server Pool feature facilitates easy deployment of the sever farm model within the
Cisco UCS. This document shows you how to create Server Pools that provide a method to use multiple
