Announcing Cisco Nexus 1000V for VMware vSphere 6 Release (Cisco Blog Repost)

Source: Cisco Blog

The Cisco Nexus 1000V has been supported in VMware vSphere hypervisor since 4.0 release (August 2009) up to the current vSphere release 5.5 update 2.  We are happy to announce that the Nexus 1000V will continue to be supported in the latest vSphere 6 release which VMware recently announced. Customers who are currently running Nexus 1000V will be able to upgrade to the vSphere 6 release and the new vSphere 6 customers will have the Nexus 1000V as part of their choices for virtual networking.

Cisco is fully committed to support the Nexus 1000V product for our 10,000+ Advanced Edition customers and the thousands more using the Essential Edition software in all future releases of VMware vSphere. Cisco has a significant virtual switching R&D investment with hundreds of engineers dedicated to the Nexus 1000V platform.  The Nexus 1000V has been the industry’s leading virtual switching platform with innovations on VXLAN (industry’s first shipping VXLAN platform), and distributed zone firewall (via Virtual Security Gateway released in Jan 2011).

The Nexus 1000V also 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.

In the last major release of the Nexus 1000V for vSphere, version 3.1 (August 2014) we added significant scaling and security features and we continue to provide subsequent updates (December 2014) with the next release planned for March 2015. The recently released capabilities include:

  • Increased scale per Nexus 1000V:
    • 250 hosts
    • 10,000 virtual ports
    • 1,000 virtual ports per host
    • 6,000 VXLAN segments with ability to scale out via BGP
  • Increased security and visibility
    • Seamless security policy from campus and WAN to datacenter with Cisco TrustSec tagging/enforcement capabilities
    • Distributed port-security for scalable anti-spoofing deployment
    • Enhanced L2 security and loop prevention with BPDU Guard
    • Protection against broadcast storms and or attacks with Storm control
    • Scalable flow accounting and statistics with Distributed Netflow
  • Ease of management via Virtual Switch Update Manager (VSUM) – a vSphere web-client plug-in

One of the common questions coming from our customers is whether VMware is still re-selling and supporting the Nexus 1000V via VMware support?

VMware has decided to no longer offer Nexus 1000V through VMware sales or sell support for the Nexus 1000V through the VMware support organization as of Feb 2nd 2015.  We want to reiterate that this has NO IMPACT on the availability and associated support from Cisco for the Nexus 1000V running in a vSphere environment.  Cisco will continue to sell Nexus 1000V and offer support contracts. Cisco encourages customers who are currently using VMware support for the Nexus 1000V to migrate their support contracts to Cisco by contacting their local Cisco Sales team to aide in this transition.

New Cisco Validated Design for XenDesktop on VNX for 5000 users

This new 5000-user CVD joins the VSPEX CVDs for both VMware View and Citrix XenDesktop in smaller increments – and also CVDs for general purpose cloud use cases based on Hyper-V and VMware.

BTW – you can of course use this to scale up even further in building blocks.

Mike Brennan, the Cisco guy who was one the folks leading this effort comments on his findings through the experience in his blog here.  It’s pretty amazing.   5000 users, up and running in 30 minutes.  The EMC VNX7500 in the test was used in a “unified way” – using block storage for UCS boot, and as part of a large pool for PVS boot vDisks, but also using NFS for PVS Write Caching.   EMC FAST Cache was used liberally to ensure a nice low-latency envelope all the way up to 39 UCS B230 M2 blades for the full 5000 user ramp up test.
