Next-generation network solutions

Dan Vargas | March 14, 2013
From a data center perspective, the last five years have been very interesting. We've seen a huge push by customers of all sizes to reduce costs and improve data center performance and resiliency.

Next-generation solutions also support innovation with their advanced features. Moving to a solution like Nexus 7000 can remedy real-world challenges attributed in large part to virtualization and consolidation in rapidly growing and evolving data centers, with features like:

  • Virtual Device Context (VDC), which enables organizations to virtualize their switch for Collapsed Core/Aggregation, R&D, DMZ deployments. The Nexus 7000, for example, supports true chassis virtualization. Essentially, you can allocate memory to each virtual device context, in addition to CPU shares and configuration files -- all while maintaining flexible separation/distribution of hardware resources and software components, data plane and control plane separation, software fault isolation and, very importantly, securely delineated administrative contexts.
  • Overlay Transport Virtualization (OTV) with Locator/ID Separation Protocol (LISP) are other advanced features that can solve workload mobility issues. Though easy to deploy, planning is important, since OTV-LISP enables customers to extend mission-critical applications across any transport between data centers. The planning is key when considering which applications are mission critical and on which VLANs to extend. Once OTV and LISP are running, organizations can benefit from dynamic real time workload mobility and disaster recovery across multiple data centers.

The list of advanced features for next-generation solutions such as Cisco's Unified Data Center and the Nexus 7000 is longer than we can discuss in this article, but again, it is all about your organization's unique needs. Today's data center solutions are dramatically different from what was available five years ago, and they are designed to address specific data center challenges faced by organizations of all sizes. Take some time to consider what they might do for yours.
