Introducing Nexus 6000 Series – Industry’s Highest Density Layer 2/3 40 Gigabit Fixed Switch

The evolution of the applications environment is creating new demands on IT and in the data center. Broad adoption of scale-out application architectures (i.e. big data), workload virtualization and cloud deployments are demanding greater scalability across the fabric. The increase in east/west (i.e. server-to-server) traffic along with the higher adoption of 10GbE in the server access layer is driving higher bandwidth requirements in the upstream links.

Following up on the introduction of 40GE/100GE on the Nexus 7000 Series, today we unveil the new Nexus 6000 Series, expanding Cisco’s Unified Fabric data center switching portfolio in order to provide greater deployment flexibility through higher density and scalability in an energy efficient form factor.  

The Cisco Nexus 6000 Series is industry’s highest density full-featured Layer 2 / Layer 3 40 Gigabit data center fixed switch with Ethernet and Fiber Channel over Ethernet (FCoE) – an industry first!In addition to high scalability, Nexus 6000 Series offers operational efficiency, superior visibility and agility 

Some say “Nexus 6000 Series is a red carpet platform that will turn heads”. We agree! It’s because of …

Cisco VXLAN Innovations Overcoming IP Multicast Challenges

At Cisco Live! in London this week, Cisco is demonstrating some enhancements to its Nexus 1000V virtual switch that greatly ease some of the challenges in deploying VXLAN in large scale cloud networks. VXLAN was designed to solve the problem of setting up traditional virtual networks (VLANs) in large multi-tenant cloud environments: the limited ID range for VLAN tags was quickly exhausted and a larger ID pool was needed for larger shared infrastructures. VXLAN thus becomes the foundation for a virtual network tunnel or virtual network overlays on top of physical networks. And unlike VLANs, VXLANs are designed to act as L2 virtual networks over L3 physical networks. For a more in-depth refresher on VXLAN, start here.

While VXLANs have certainly enabled a whole new level of scalability for virtual networks, one of the challenges in deploying VXLAN is its use of IP Multicast to implement the L2 over L3 network capability. Why is this? VXLAN is a MAC-in-IP encapsulation protocol in a UDP frame. The virtual switch that acts as the VXLAN termination (in Cisco’s case, the Nexus 1000V virtual switch) takes the L2 packet from the VM, wraps it in a L3 IP header, and sends it out over UDP. But the challenge is that there’s no way to determine which IP address should be used for the destination host (VXLAN termination point) at which the desired MAC address can be found. In other protocols, this can be accomplished within the network control plane and some MAC to IP mapping protocol, but the VXLAN specification indicates there should be no reliance on a control plane or a physical to virtual mapping table.

Nexus 1000V Expands Cloud Network Services Ecosystem with vPath Integration in the Imperva Web Application Firewall

Nexus 1110 Imperva-2We are ramping up another news cycle around our Nexus 1000V and cloud network services portfolio this week at Cisco live! in London. Among the updates, business security solutions vendor Imperva is demonstrating integration of its SecureSphere Web Application Firewall (WAF) into the Nexus 1000V vPath service insertion architecture. This marks the first third party product to participate in the Cisco vPath architecture, which allows virtual services to be easily inserted and chained into Cisco virtual networks and virtual overlays.

Regular readers of our data center and cloud blog will probably recall the importance of vPath in enabling virtual services for virtualized multi-tenant cloud environments, and for allowing policy mobility along with VM mobility. The Cisco vPath architecture currently supports our own virtual services including Virtual Security Gateway (VSG), the ASA 1000V Cloud Firewall, and virtual WAAS for WAN optimization. vPath also boosts performance of service traffic paths and orchestrates service chaining so that VM traffic is processed in a ordered chain defined by policy.

Citrix NetScaler VPX gets going on the Cisco 1110 Virtual Network Services platform

 This week at Cisco live! in London, Citrix is demonstrating the Citrix NetScaler VPX virtual application delivery controller (vADC) on the Nexus 1110 Cloud Services Platform . NetScaler VPX is the industry-leading vADC and is further testimony to the expanding ecosystem for the Cisco Nexus 1000V virtual networking portfolio and the Cloud Network Services platform. The integrated Cisco-Citrix solution follows on the heels of last year’s agreement by the two companies that Cisco would reference sell the Citrix NetScaler portfolio, and Cisco’s demonstration of its Nexus 1000V virtual networking portfolio on Citrix XenServer.



The Nexus 1110 is the latest generation of appliances that started with the Nexus 1010. The Nexus 1110 helps customers that are virtualizing more of their application and security services and want to run them on a dedicated platform. For example, virtual firewalls, like our Virtual Security Gateway (VSG), complement physical firewall appliances to support virtual application deployments and VM mobility requirements. The Nexus 1110 appliance serves that need, running a range of virtual services on a platform that the networking and security teams can more directly control than the other application servers.

With Citrix NetScaler VPX integrated into the Nexus 1110 Cloud Services Platform, enterprise IT admins can scale-out deployments by enabling additional virtual NetScaler instances (VM’s) directly from the Nexus 1110. NetScaler VPX also provides feature and management consistency across physical and virtual ADC’s, as well as consistency across physical and virtual workloads that are being managed. The NetScaler portfolio includes two other physical appliances, MPX and SDX. The virtual VPX can also load balance across both physical and virtual servers, as well as multiple web servers, application servers and database servers.
