The most valuable features are the service profiles and the unified management of both network and storage. With UCS, it's quite easy to deploy. Whenever there's a failure of any component, it's very easy to swap because you just disassociate that profile, remove the faulty blade, connect the new blade, and associate that profile, maintaining the same MAC address and worldwide port name. Everything remains the same, and it's only the hardware that you're replacing. This makes it very easy for me to manage and troubleshoot.
