The Dirty Secrets of Server Power

Power efficiency remains a top decision point for many customers looking to modernize their data center. Customers searching for an accurate way to compare server power among vendors are often directed to use power calculators without taking into account the many factors that drive power utilization. This notion preys on the simplistic nature of the power beast – lower number is better… but are we missing the (power) bus entirely?

The dirty little secret is that there is no industry standard for power calculators, and vendors can essentially publish a calculator around whatever workload they like (or no actual workload at all). Read More »

OpenDaylight: Building an Open Source Community around SDN

It’s great to see Cisco and many companies across the industry make a major change in the use of Open Source via the newly form project hosted by the Linux Foundation called OpenDaylight. This consortium is an industry-wide, open and transparent effort to catalyze innovation and accelerate an application ecosystem for software-defined networking. With all the partners involved we are working to not only further development and adoption of SDN but also to foster a new developer community. A consortium like this has been long overdue and it’s great to finally see it come to fruition.

We are incredibly pleased to partner with Arista, Big Switch Networks, Brocade, Citrix, Dell, Ericsson, Fujitsu, HP, IBM, Intel, Juniper Networks, Microsoft, NEC, Nuage Networks, PLUMgrid, RedHat and VMware on the Project. This is the largest effort to date to drive Software-Defined Networking across the industry and into new markets.  While the initial goal is to build a common, industry backed SDN Platform, the broader objective is to give rise to an entire ecosystem of developers that can freely utilize the code, contribute to the project and commercialize the offerings. I further expect the ecosystem to expand into areas like tools and services.

Cisco has donated our core “Cisco ONE” controller code to the project and has officially open sourced the code under the Eclipse Public License. The community has come together around this code to form the architecture (see below) for the Open SDN Framework. Beyond donations of code, Project members are supporting the project via both financial investment and via developers we are committing to work full-time on the project overall. Donations from other members of the Project can be seen here and we expect this list to only grow.

As Open Source increasingly becomes a standard for customers and developers, we look at this as a new way to meet our customer needs and also help developers innovate in new ways without the barriers of vendor lock-in. Open Source is increasingly important for our customers and developers as well and as they evolve, we evolve. Cisco to date has supported Open Source through efforts such as OpenStack and now OpenDaylight and we look at Open Source as a critical pillar in our software strategy moving forward. By allowing developers to freely use these solutions we hope to enable a new developer ecosystem for software-defined networking and more. We are fully committed to enabling developers, both current and new, to deliver innovating applications and services that will help customers across the board realize the value of SDN faster than before.

The OpenDaylight architecture and code offering to date includes a modular southbound plugin architecture for multi-vendor environments. In addition, OpenDaylight offers an extensible northbound framework with both Java & REST APIs to ensure multiple developer skill-sets can build applications to the platform. We are also planning to build a onePK plugin for OpenDaylight to enable multiple users to drive network intelligence into their SDN applications. As you can see from below we will also be supporting key standards with this effort, including OpenFlow.

 

OpenDaylight

 

It’s important to note that you don’t launch a community; you build one. By investing in OpenDaylight we hope that our customers, partners and developers across multiple industries will now have the ability to build applications that frankly make the network easier to use and more automated. As an industry we are moving in a new direction and further up the stack and OpenDaylight offers new opportunities for application creation and monetization beyond the networking layer.

It’s a true rarity when you see both partners and competitors come together for the good of the community, and contribute code for the universal good of the customer. All OpenDaylight participants have committed to open source guidelines that include open communication, ethical and honest behavior, code and roadmap transparency and more. An Open Source project is only as successful as the community of developers and the level of code quality, and OpenDaylight’s Board of Directors (which includes multiple parties cross-industry) will be ensuring that partners, code contributors and project committers all abide by the same guidelines for the success of the project over the success of their own company’s offerings.

For more information, please see www.opendaylight.org. Code will be available for download soon, and we are looking for interested individuals for commitments across the board – from technical offerings to application development, and we welcome contributions from both individuals and other organizations. All ideas are welcome, and we look forward to multiple new innovative solutions coming from this.

Congratulations to all our partners and individuals who helped to make this happen, including the hard work done by the Linux Foundation. It’s truly an amazing accomplishment and we expect to see much more in the near future.

Judge for yourself: Taking Dell to task on “holistic” security claims

In case you missed it, Network World’s Ellen Messmer published a rather surprising article on how Dell was going to “trump” Cisco in the information security market as a result of some recent acquisitions. Now certainly Dell is entitled to their beliefs. They’re in a difficult position right now, as Michael Dell and Silver Lake maneuver the company through a very complex set of buy-out related transactions. They need to give their customers assurance that they won’t be distracted through this process. And if you want to set a big impression with your customers, you might as well go after the market leader in security.  Be it as it may, we can’t just sit back and let these blatant statements go unchecked. So, in the spirit of “fair and balanced” reporting, we thought we’d issue our own little fact check and let you conclude for yourself.

  • “Cisco is a great competitor but they don’t have our holistic view” – Acquiring assets and bundling them together doesn’t constitute a “holistic” approach.  Those assets must be closely integrated, which is the approach Cisco is delivering with its next generation security architecture. This architecture will be built on top of a multi-function security platform with deep network integration. There are many proof points today that demonstrate we are delivering against this strategy and architecture. Today our customers are deploying Cloud Web Security with their Cisco ISR G2 and ASA Next Generation Firewall through connectors built from Cloud Web Security. In addition we’ve brought market leading application, visibility and control to ASA, embedded deep in the firewall.  But it doesn’t stop here.
  • Now what about Dell’s comment that Cisco “doesn’t have an identity business“?  Cisco’s Identity Services Engine provides the backbone of Cisco’s secure Unified Access solution. The real network security action is in delivering access privileges based on more than just user identity and group which is all Dell can do today with Quest. In the BYOD world customers also require action based on the type of device, posture of the device, and location. Cisco’s Identity Services Engine is the industry leading platform to deliver context based policy controls and then leveraging the network for distributed enforcement consistently across wired, wireless, and VPN access. This is a game-changer for the enterprise and our next generation end-to-end security architecture. Enterprises can now implement context-based policy from the access layer through the data center switching fabric without using brittle and costly network segmentation methods tied to VLANs and ACLs. This is real synergy, and it is delivering a holistic solution as opposed to a holistic press sound bite.  But don’t just take our word for it; check out Gartner’s latest Magic Quadrant for NAC.  Cisco’s ISE combines identity, device, and network with a market leading platform deployed in over 3000 customers.
  • Just weeks ago we announced another key milestone with the introduction of ISE 1.2.  With this latest release we also became the first vendor in the industry to offer automated profiling feeds making us better and faster at identifying new devices and operating systems.  We’ve increased the speed and scalability of ISE to address the increasing demands brought on by the “Internet of Everything”.  And we’ve added a new set of partner APIs enabling integration into key MDM partners – SAP, AirWatch, Citrix, Mobile Iron and Good.  This expands the reach of ISE and enables customers to drive common context and identity management from the network all the way to the end point.  Dell talk’s about their direction to advance the “concept” of embedded security to virtually any type of device.  We’re not just talking about it, we’re doing it.
