Why Cisco UCS Rocks #3: Simplicity
True simplicity is so much more than just the absence of clutter or the removal of decoration. It’s about offering up the right things, in the right place, right when you need them. It’s about bringing order to complexity. And it’s about making something that always seems to “just work.” When you pick something up for the first time and already know how to do the things you want to do, that’s simplicity. — Apple.com
And cabling it up couldn't be simpler: plug in the four power supplies, cable just two of the ports on each I/O Module (IOM) to the Fabric Interconnect and bam! Eight servers are cabled and ready to go.
We installed eight servers on Cisco UCS within 30 minutes of taking it out of the box.

Heil . . . estimates that his team saved one to two weeks [on installation time] for all sixteen servers and approximately $17,000 in cabling/port licensing expenses.

One source of the increased efficiency is simplified cabling. In the previous environment, each blade enclosure required ten Gigabit Ethernet cables and five Fibre Channel cables, each of which had to be painstakingly labeled. Now, all server blades in all Cisco UCS chassis connect to the data and storage networks through a single pair of Cisco 6100 Fabric Interconnects, wired with two Ethernet and two Fibre Channel cables. “We cabled the Cisco UCS once, and haven’t had to touch the cables since,” says Okuma.

SingleConnect technology combines three network layers into one: top of rack, blade chassis, and server hypervisor switching. It simultaneously unifies LAN, SAN, and server systems management networks on a single fabric.
The Cisco UCS not only accelerates server provisioning, it also decreases new server costs. “We’ll pay less to add compute capacity to the Cisco UCS, because we’ll only need to provision a new server blade, not additional cables, network interface cards, and host bus adapters."
