Much has been made of the emergence of Software Defined Networking and the programmable network. At its core, SDN involves opening up network interfaces in order to make the network programmable and allow for the development of applications. While some of those applications interact directly with the data plane, determining how individual packets are treated, many applications actually involve what can fundamentally be described as management functionality – automation of workflows, reaction to events, closing of control loops. A popular example concerns orchestration, in which resources are allocated and state modified so that collectively a service is provided – in many ways resembling a reincarnation of service provisioning in a new context and under a new name.
Of course, management applications and management interfaces have been around for a long time, so what is really new and different this time? Is SDN simply an exciting new label for a tired old concept? Does SDN obviate the need for traditional management? At the core of these questions are the concepts of programmability and manageability. Read More »

John Horrigan spends a lot of time worrying about the digital divide – the chasm that divides certain demographic sectors when it comes to accessing information, transacting business, and interacting with government.
I wrote about this last year in Broadband: Exploring The Demographic Patterns, but Horrigan has dug a little deeper, both in his former position with Pew Internet Research and his current position as vice-president and director of the Media and Technology Institute at Washington, D.C.’s Joint Center for Political and Economic Studies.

Domain 7 in our Cisco Domain TenSM framework for data center transformation is what we call “Platform”. More specifically, this term refers to the “software platform” upon which your business applications will run. In short, this area is where we examine operating systems, databases and other types of middleware and help you figure out your strategy, architectural decisions and implementation plans in these areas, to help you drive a more successful cloud or data center project. Let’s discuss this area in more detail.
First, though, if you are new to the Cisco Domain Ten, please check out my “Cisco Domain Ten: The Story So Far” summary blog I published recently. Additionally, earlier this week, we ran a public webinar, where some of my colleagues in the Cisco Data Center and Cloud Services team gave their perspectives on Cisco Domain Ten. If you missed this and their very practical insights, please do catch up on the Cisco Domain Ten webinar recording.

Organizations use Cisco UCS servers to gain the power, flexibility, and management simplicity needed to meet their Microsoft SQL Server workload demands while increasing their IT agility.
Starting with standalone servers for performance and bandwidth, or connecting servers through Cisco UCS for automated configuration, simplified management, and massive I/O flexibility which provide SAN and network-attached storage (NAS) access, the pairing of Microsoft SQL Server with Cisco UCS provides business intelligence and OLTP applications exceptional connectivity to your data.
Let’s not about record-setting performance with lower cost, too! In its inaugural TPC-H™ result, Cisco asserted industry leadership in partnership with Microsoft, establishing Cisco UCS as the fastest 4-socket Intel Xeon processor– powered platform for running Microsoft SQL Server at the 1,000 GB scale factor.
Table 1 below outlines the flexibility of SQL Server on UCS, describing various sized configurations to support your data management needs. Here you can see how our B series or C series UCS servers support small to medium organizations up to the largest of enterprises.
Table 1 -- UCS SQL Server Sample Configurations
Want to learn more about Microsoft applications on Cisco UCS? Then please feel free to download in this new Application Solutions Brochure and see how UCS provides an optimal platform for Microsoft SQL Server, SharePoint and other leading applications.

Network Management is dull. No excuses. Monitoring and interacting with the devices that move data from one location to another is a thankless undertaking that most of us building networks leave to an afterthought. Part of that is the complexity associated with managing networks. There are at least a dozen common methods for interacting with devices in the network including SNMP, CLI, AAA, Syslog, Netflow, and fancy XML/HTTP interfaces. So much variety breeds complexity so we tend to set our goals pretty low for interactivity with the network.
What if we had one common mechanism for interacting with the network? Different devices running different software would all speak a common language to the applications managing and monitoring them. Now what if that language was something the programmers writing those applications understood implicitly like an API library they could compile directly into their program? That would make interacting with the network as simple as making a procedure call within the application. That’s exactly what onePK – or the “one Platform Kit” – accomplishes.
