When customers talk about why they like UCS they often sum it up in very concise terms. "It makes things a lot easier," is a common refrain. But if you ask a Cisco technologist what's good about UCS you'll get a much more lengthy reply, probably more than you wanted to hear. That's because when anyone fully describes all of the innovations in the solution, "under the covers," so to speak, which conspire to bring about UCS benefits, they quickly find themselves reciting a rather long list of complex advancements. As I spend time in our booth at VMworld this week I hear both of these accounts of UCS. The long (how it rocks) and the short (why it rocks.)  As luck would have it, some intrepid UCS product marketers have taken it upon themselves to bridge this yawning gap in the UCS lexicon.

First, remember that UCS is an outcome of starting with a clean sheet of paper and designing a system to rectify all the random acts of system architecture that had come before it. It's also an outcome of a completely revolutionary way of approaching computing: not from the perspective of the constituent technologies but from the perspective of fusing them all together. UCS was expressly designed to eliminate the DIY integration that customers have been faced with for years. It was designed for a world of virtualization, automation and cloud. Fundamentally, UCS was designed to connect all the dots.

With the connections in mind, we're introducing a technology ingredient brand into the UCS lexicon: Cisco SingleConnect Technology.

SingleConnect is a term intended to encapsulate the aggregated benefits of several key UCS technology components as they relate to server connectivity: Cisco Fabric Interconnects, Fabric Extenders, Virtual Interface Cards and Virtual Machine Fabric Extender Technology (VM-FEX.) Related technologies like the Nexus 1000v suite and Cisco's virtualized network services also come into view when we talk about connecting physical and virtual servers in the data center.

Each of these deeply sophisticated products plays a specific role, but taken altogether they create an elegant result: a simplified, uniform and extremely powerful connectivity model for servers andvirtual machines. SingleConnect is way for us to describe how all of these together result inone connectionfor:

? LAN, SAN,andsystems management

? Rack serversandblade servers

? Physical serversand virtual machines

SingleConnect, very simply, is the easiest, most intelligent and efficient way to connect and manage computing in the data center.

SingleConnect is Easy:UCS is a "wire once and walk away" solution that eliminates many of the traditional time-consuming, manual and error-prone tasks required to connect servers and virtual machines in the data center. UCS with SingleConnect is self-integrating, with automated and dynamic configuration of server I/O and networking components over a common connection. UCS centralizes administration, eliminating dozens of switching and server management points found in traditional environments while radically reducing cable management complexity.

SingleConnect is Efficient:SingleConnect Technology combines three network layers into one: top of rack, blade chassis and hypervisor switching. It also combines LAN, SAN and server systems management networks on a single fabric. Modular fabric extenders deliver capacity from a centralized fabric interconnect (single point of management) to as many as 160 servers, replacing all the Ethernet and FibreChannel switches typically deployed in much smaller server increments. Server I/O adapters (NICs, and HBA's) are consolidated onto a single Virtual Interface Card, eliminating cost and simplifying administration.

SingleConnect is Intelligent:SingleConnect technology creates a virtualization-aware system, providing seamless VM mobility and advanced security capabilities for multi-tenant environments. I/O capacity is dynamically allocated across physical and virtual machines in the system in accordance with QOS policies, eliminating the need for manual administrator intervention and simplifying troubleshooting. Deterministic, low latency switching delivers industry leading bare metal and virtualized performance for traditional multi-tier application environments and cloud workloads alike.

Cisco SingleConnect Technology is not a specific product or feature, it is a way to describe how a deliberate roadmap of innovation solves against one of the oldest computing problems in the data center: "how do I connect all this stuff together?"

With SingleConnect!

If you're at VMworld in San Francisco this week, stop by the Cisco booth and we can give you demo of how SingleConnect brings it all together.
