The onePK Software Architecture

This post is about the onePK software architecture, and how it allows us to consistently expose network operating system (NOS) features to a wide variety of programming environments for IOS, IOS-XE, IOS-XR and NXOS.

For an overview of onePK in general, and some more context, see my October 2012 post and my slides in Slideshare.

What Is Cisco UNIFIED FABRIC? Why Should You Care?

Is your network ready to help you transform and be the strategic partner that you can be? Let’s face it… Today’s data centers are challenged with siloed resources and facilities… Limited scalability… Poor resource utilization… Growing complexity…Perhaps the biggest challenge is time.  When 80% of your resources are dedicated to “keeping the lights on” and managing all what you have, there is very little time left for innovation that benefits the business.

And the reality is that the role of IT has to change – from a cost center to a business strategic partner!  Why? Because there are increasing demands on IT to help your business differentiate in order to survive and grow in these rough economic conditions. And let’s not forget that the increasing cost pressures, technology changes, and the advent of game-changers like cloud are forcing IT executives to look at how to deliver IT differently.

NX-OS: Delivering Ongoing Value

When we talk about networks in the data center, there is often talk about bandwidth, 10Gigabit Ethernet, switch sizing, and the changes that have been wrought on the network since the inception of widespread server virtualization. The base operating system that the switch runs on, the networking software itself, is often only discussed in terms of how/when/why to do upgrades. Networking software has more relevance than that, especially from a strategic standpoint.

The strategic nature of networking software is easy to see. But the most important way networking software is important is in the flexibility it can provide over the lifetime of the product line. Poorly written or architected networking software can put a huge burden on the vendor when new features or when major changes to the networking industry occurs. As a customer that matters because the vendor may spend the time and money to accommodate those changes or has to charge an exorbitant amount. It all speaks to the investment protection a vendor can bring. Poor network software equals poor investment protection and a degraded upgrade path.
