There are a number of trends that are impacting data centers today, many of which will have a profound impact on how businesses consume data center resources. These can provide a variety of challenges. Perhaps most obvious, is the fact that people and businesses are more connected than ever with the proliferation of mobile devices and tablets. These new devices are driving more applications, more users, and an insatiable appetite for network bandwidth. This blog will discuss a few of these trends and how Cisco is shaping its data center strategy to enable customers to meet these rapidly changing demands.
Another major data center trend that is driving change in the data center is the continued adoption of virtualization technologies. What’s interesting is that although server spending has remained relatively flat for over a decade, there is still a great deal of “head room” for companies to further adopt virtualization.
In fact, IDC studies show that many applications are yet to be virtualized as the chart to the right indicates. However, virtualization is driving complexity elsewhere including the network, software and storage. So what has created a more agile server, has not necessarily created a more agile system.
The next major trend is that of Cloud Computing, with more business leveraging private, public or potentially even hybrid cloud models. Some actually forecast that there could eventually be a small number of mega data centers and companies will all leverage capacity exclusively from these since they can offer extreme efficiencies. The truth is, there are two ends of the spectrum, some customers will prefer to host their own infrastructure and others may choose to use Cloud providers exclusively. We are finding today that many customers are somewhere in the middle and choose their model based on the application needs.

Maybe you’re like me, looking for any excuse to hop on a plane to Boston! In this case, I happen to have a good one, Red Hat Summit, which kicks off on June 11th.
Cisco is proud to be a Platinum Sponsor for the event and we’re showing up in full force with a larger booth, more demos, a Cisco keynote, breakout, and a number of new solution areas that we plan to showcase. We’ll have a number of product and solution experts available to share our view on how Cisco Solutions, hosted on UCS infrastructure, are building a better data center.
One presentation you should be sure not to miss is the Cisco Keynote on Wednesday, June 12th at 9:30 AM with Ram Appalaraju, Vice President of Technology, Products and Solutions Engineering at Cisco. It’s safe to say, Ram has an important role at Cisco. He is essentially responsible for delivering Cisco’s Unified Data Center strategy in the form of products and solutions. This will certainly prove to be a presentation not to be missed!
In addition, Han Yang, Product Manager for Cisco Nexus 1000V, will discuss the Nexus 1000V on KVM with OpenStack Integration. Since Han was one of the original Engineers developing the Nexus 1000V, this makes him uniquely qualified to present this breakout. This session will be held in room 312 on Thursday, June 13th at 1:20 pm.
Please see below for the four key solutions that Cisco is showcasing at the Partner Pavillion:

In the last fiscal quarter Cisco UCS reached another milestone with 20,000 (87% Y/Y growth) customers. The (no longer) new data center paradigm of fabric based computing must be resulting in unique customer benefits, and hence the market traction. Gartner defines Fabric based computing as follows:
Fabric-based computing (FBC) is a modular form of computing in which a system can be aggregated from separate (or disaggregated) building-block modules connected over a fabric or switched backplane. Fabric-based infrastructure (FBI) differs from FBC by enabling existing technology elements to be grouped and packaged in a fabric-enabled environment, while the technology elements of an FBC solution will be designed solely around the fabric implementation model.
In this video Gartner analyst Donna Scott and Cisco CTO Paul Perez discuss the adoption of Fabric-based computing and the benefits that customers experience with it.
I will dive deeper into why customers experience benefits with the Cisco Unified Computing System. So lets start with the term “Fabric”. A Lippis report helps us understand the data center fabric. In this tech target article by Michael Brandenburg we get some more background.
Legacy three-tiered data center architecture was designed to service the heavy north-south traffic of client-server applications, while enabling network administrators to manage the flow of traffic. Engineers adopted spanning tree protocol (STP) in these architectures to optimize the path from the client to server and allow for link redundancy. STP worked well to support client-server applications and its traffic flows, but proved inefficient for server-to-server or east-west communications associated with distributed application architecture.
…Server virtualization compounds the problem with spanning tree and the three-tiered architecture.
… data center fabric, a network where traffic from any port can reach any other node with as few latency-inducing hops as possible.
This is eye opening for those of us who live in the server and application world. Bottom line – the data center fabric will result in fewer hops and lower latency for servers communicating with each other in the data center.
So how is this achieved within the Cisco Unified Computing System? This is done with the Fabric Interconnect, which is the I/O hub and the very soul of the system. The Fabric interconnect consolidates three separate networks: LANs, SANs, and high-performance computing networks. The Fabric Interconnect provides consolidated access to both SAN storage and network attached storage (NAS) over the fabric. This means the Cisco Unified Computing System servers can access storage over Ethernet, Fibre Channel, Fibre Channel over Ethernet (FCoE), and iSCSI. It also lowers costs by reducing the number of network adapters, switches, and cables.
The Cisco UCS Manager, which is the embedded device manger software in the Fabric Interconnect, gives users the ability to slice and dice this big chunk of physical network capacity of the system into much smaller subunits, with the ability to do it flexibly and to change the decisions with software configuration. With Cisco UCS, IT organizations can now deliver dynamic network infrastructure or network services across all types of applications—from applications like Oracle, SAP, three tier J2EEE, and Microsoft to virtualized applications from VMware, Microsoft, and Citrix.
In his blog John McCool ,Cisco SVP and CTO, defines Fabric as “… a highly available, high performance shared infrastructure built with integrated, intelligent compute, storage and network nodes that can be rapidly and simply organized around the requirements of a given workload.” In part 2 of this blog I will detail the automation and management of the fabric-based compute nodes (upto 160) connected to a single pair of UCS Fabric Interconnects.
