Today marks the general availability of the eagerly-awaited Microsoft Windows Server 2012 platform. According to Microsoft, “Windows Server 2012 redefines the server category, delivering hundreds of new features and enhancements spanning virtualization, networking, storage, user experience, cloud computing, automation, and more.” Earlier Cisco blog posts discussed how Cisco has collaborated with Microsoft to achieve Windows 2012 certification for our UCS servers, as well as integrating our management tools into Microsoft System Center and PowerShell.
In this post, I’d like to highlight the integration of the Nexus 1000V virtual switch into the Windows Server 2012 platform, and particularly the Hyper-V hypervisor. We have been working closely with the Windows Server 2012 team for the past few years towards this goal, and announced Nexus 1000V and VM-FEX support for it at the Microsoft BUILD conference last year.

Nothing sits around and gets stale for long at Cisco (outside the break rooms anyway). On the heels of shipping our Nexus 1000V 1.5.2 release earlier this week (which you can download from here), we are ramping up to show the upcoming generation of the virtual switch next week at VMworld in San Francisco. This new major release 2.1 will be going into beta in October, and will represent a quantum leap in ease of deployment and management, as well as greater security for cloud environments.
vCenter Plug-in – Provides a holistic view of the virtual network to the server administrator from within VMware vCenter. A Nexus 1000V dashboard in vCenter shows the virtual supervisor module (VSM) and virtual ethernet module (VEM) details, such as VSM health status, license information, PNIC information, connected VM’s, et al.
Support for Cisco TrustSec -- Extends Cisco TrustSec security solutions for network-based segmentation of users and physical workloads to virtual workloads, leveraging Security Group Tags (SGT) for defining security segments. Data center segmentation and consistent security policy enforcement can now be implemented across physical and virtual workloads.
Cross Data Center High-availability – Supports split Active and Standby Nexus 1000V Virtual Supervisor Modules (VSMs) across two data centers to implement cross-DC clusters and VM mobility while ensuring high availability. In addition, VSM’s in the data center can support VEM’s at remote branch offices. Read More »
Today Cisco made a new version of its Nexus 1000V virtual switch available for immediate download. The newly available Nexus 1000V 1.5.2 release can be downloaded for a 60 day free trial from here. As most of you know because you’ve been reading all my blog posts over the last year, the Nexus 1000V is the edge switch for virtual environments, bringing the network edge right up to the virtual machine, by residing in the hypervisors and connecting virtual ports to the physical network and beyond. The Nexus 1000V is the foundation for our entire virtual network overlay portfolio, including all of our virtual L4-7 application and security services, our cloud orchestration software, VXLANs and more.
The new release supports the latest version of VMware’s vSphere hypervisor, and includes vPath 2.0 with service chaining between virtual services. I wrote a blog post a couple of weeks ago about the importance of vPath in inserting virtual services into data center networks, and now we also have a great new white paper available on vPath service insertion technology. The most important enhancement in vPath 2.0 is that you can now insert multiple services in the path between the source and destination addresses in your virtual network. Read More »
VMworld 2012 is around the corner, and like the past years , Cisco as a key player in the word of network, virtualization and now servers with the Unified Computing Systems, is a sponsor .
In the following days you will read on this blogs a series of information on our participation . But I encourage you to check today the following website to have a good overview of what we will present in terms of demos on our booth (#1213) , but also what are the key sessions we are leading .

Amongst the numerous solutions, I know for a fact (based on the numbers of readers of our blogs), that VXLAN is a very compelling topic. So I invited Han Yang to introduce his session:
Best Practice for deploying VXLAN with Cisco Nexus 1000V and VMware Cloud Director INF–NET2373, Tuesday August 28 5:00 pm – 6:00 pm
If you want to know more about VXLAN, please check the recent blogs on this topic by Gary Kinghorn and Omar Sultan:
The lack of programmability in existing networking hardware is certainly a problem, but VMware’s acquisition of Nicira does not mean that Cisco and its ilk will be marginalized… It does mean the role and management of the physical network is changing, and I think Cisco is further ahead than most of its competitors in creating a vision for the next phase of networking.
My take here was that the VMware-Nicira acquisition did not portend a strategic break with Cisco, and while there are some obvious overlaps in our product lines, there are still a number of areas of collaboration, cooperation and interoperability. The virtual network infrastructure is just one piece of a larger software stack and the differentiation will likely be decided in the orchestration, management and applications built on top of the newly programmable infrastructures sometime down the road.
