Power of Open Choice in Hypervisor Virtual Switching

July 28, 2014 at 5:00 am PST

Customers gain great value from server virtualization in the form of virtual machines (VM) and more recently Linux Containers /Dockers in data centers, clouds and branches.  By some estimates, more than 60 % of the workloads are virtualized although less than 16% of the physical servers (IDC) are virtualized (running a hypervisor).  From a networking perspective, the hypervisor virtual switch on these virtualized servers plays a critical component in all current and future data center, cloud, and branch designs and solutions

As we count down to the annual VMworld conference and reflect on the introduction of the Cisco Nexus 1000V in vSphere 4.0 six years ago, we can feel proud of what we have achieved. We have to congratulate VMware for their partnership and success in opening vSphere networking to third party vendors. It was beneficial for our joint customers, and for both companies. VMware and Cisco could be considered visionaries in this sense. Recognizing this success, the industry has followed.

Similarly we praise Microsoft as well, for having also provided an open environment for third-party virtual switches within Hyper-V, which has continued gaining market share recently.  Cisco and Microsoft (along with other industry players) are leading the industry with the latest collaboration on submitting the OpFlex control protocol to the IETF. Microsoft’s intention to enable OpFlex support in their native Hyper-V virtual switch enables standards-based interaction with the virtual switches.  Another win for customers and the industry.

In KVM and Xen environments, many organizations have looked at Open vSwitch (OVS) as an open source alternative. There is an interest in having richer networking than the standard Linux Bridge provides, or using OVS as a component for implementing SDN-based solutions like network virtualization. We think that there is an appetite for OVS on other hypervisors as well.  Cisco is also committed to contributing and improving these open source efforts.  We are active contributors in the Open Virtual Switch project and diligently working to open source our OpFlex control protocol implementation for OVS in the OpenDaylight consortium.

To recap on the thoughts from above, Table 1 provides a quick glance at the options for virtual networking from multiple vendors as of today:

Table 1:  Hypervisors and Choices in Virtual Switches

Hypervisor

Native vSwitch

3-party or OpenSource  vSwitch

vSphere

•Standard vSwitch
•Distributed Virtual Switch
•Cisco Application Virtual Switch
•IBM DVS 5000V
•HP Virtual Switch 5900V

Hyper-V

Native Hyper-v Switching
•NEC
•Broadcom

KVM

Linux Bridge(some distributions include OVS natively)
•OVS

XEN

OVS -- open source project with multiple contributions from different vendors and individuals
•OVS

 

As an IT Professional, whether you are running workloads on Red Hat KVM, Microsoft Hyper-V or VMware vSphere, it is difficult to imagine not having a choice of virtual networking. For many customers, this choice still means using the hypervisor’s native vSwitch.  For others, it is about having an open source alternative, like OVS. And in many other cases, having the option of selecting an Enterprise-grade virtual switch has been key to increasing deployments of virtualization, since it enables consistent policies and network operations between virtual machines and bare metal workloads.

As can be seen in the table above, Cisco Nexus 1000V continues to be the industry’s only multi-hypervisor virtual switching solution that delivers enterprise class functionality and features across vSphere, Hyper-V and KVM. Currently, over 10,000 customers have selected this option with Cisco Nexus 1000V in either vSphere, Hyper-V, or KVM (or a combination of them).

Cisco is fully committed to the Nexus 1000V for vSphere, Hyper-V and KVM and also the Application Virtual Switch (AVS) for Application Centric Infrastructure (ACI), in addition to our open source contributions to OVS.  Cisco has a large R&D investment in virtual switching, with a lot of talented engineers dedicated to this area, inclusive of those working on open-source contributions.

Nexus 1000V 3.0 release for vSphere is slated for August 2014 (general availability). This release addresses scale requirements of our increasing customer base, as well as an easy installation tool in the form of Cisco Virtual Switch Update Manager.   The Cisco AVS for vSphere will bring the ACI policy framework to virtual servers.  With ACI, customers will for the first time benefit from a true end-to-end virtual + physical infrastructure being managed holistically to provide visibility and optimal performance for heterogeneous hypervisors and workloads (virtual or physical).  These innovations and choices are enabled by the availability of open choices in virtual switching within hypervisors.

As we look forward to VMworld next month, we are excited to continue the collaborative work with platform vendors VMware, Microsoft, Red Hat, Canonical, and the open source community to maintain and continue development of openness and choice for our customers.  We are fully committed to this vision at Cisco.

Availability of the Nexus 1000V Cloud Networking Platform for OpenStack Unveiled at Cisco live!

February 7, 2014 at 4:00 am PST

Last week at Cisco live! Milan, we announced another milestone in our OpenStack strategy with the availability this quarter of the Nexus 1000V virtual networking platform for Linux Kernel Virtual Machine (KVM) hypervisor and integration with the commercial OpenStack distribution from Canonical (Ubuntu Linux and OpenStack). I had a chance to sit down in Milan with John Zannos, VP of Global Alliances at Canonical, to talk about the Cisco-Canonical partnership, and what the integration of Nexus 1000V into their OpenStack architecture means for customers.

The Nexus 1000V on KVM brings to the OpenStack cloud a fully integrated network virtualization solution. The solution provides a full layer-2 feature set, feature-rich Layer-3 IOS router, security and QoS policies, VXLAN virtual overlays, vPath-enabled virtual services, and full monitoring and management capabilities.  Enterprises and service providers may now deploy a full-featured virtual network infrastructure consistently across VMware, Microsoft, and Linux-based software platforms.

Nexus 1000V for Ubuntu Linux with OpenStack support is now available with full automation and orchestration of enablement of the solution via Juju/Charms. Juju provides both a command-line interface and an intuitive web app to design, build, configure, deploy and manage your infrastructure. Charms give Juju its power. They encapsulate application configurations, define how services are deployed, how they connect to other services and are scaled. Nexus 1000V support for Red Hat KVM and OpenStack is planned for later this year.

Additional details and data sheets can be found here.

And on a related note, if you are interested in Nexus 1000V-related items, we recently recorded a technical podcast with Greg Ferro and Ethan Banks of packetpushers.net on the Microsoft Hyper-V version of our virtual switch, which you can find here.

Red Hat Summit, Nexus 1000V and All Things Open

June 11, 2013 at 1:20 pm PST

Red Hat SummitThis week kicked off with a trip to Boston and Red Hat Summit where Cisco is talking about our partnership with Red Hat on open source projects including OpenStack, and the Kernel-based Virtual Machine (KVM) hypervisor. I’m here to highlight some of our Nexus 1000V virtual networking innovations that involve Red Hat open source distributions of red Hat Enterprise Linux (RHEL), KVM and OpenStack.

Best of Tech Ed AwardAs you probably know, Cisco started shipping the Nexus 1000V virtual switch for Microsoft Hyper-V this month (and it won a Best of TechEd Show award at Microsoft’s TechEd conference). But open source virtualization and cloud infrastructure platforms continue to be an important strategy for our entire data center portfolio here at Cisco. KVM will be the next hypervisor that we’ll ship our Nexus 1000V virtual switch on, and the rest of the Red Hat open source cloud infrastructure will be an important part of our open strategy, and that includes Red Hat Linux and their Red Hat OpenStack distribution.
