Components of a UCS System
- Servers – These are our blades
- Service Profile Templates – This is a summary of configs such as VLAN, etc being pushed out to all blades.
- Boot Policy – This determines what’s the type of boot you prefer and here we specify the SAN boot order such as boot luns.

- IOM – IO Module provides uplink from chassis to Fabric interconnect.
- UCS Blade I/O Adapter Overview ( Cisco VIC Cards) – These cards are responsible for adapter virtualization. Up to 256 vnic can be assigned to ESXi.
