Router Cisco Nexus 1000V - five years - News

Day August 16, 2008 was an important turning point in the history of the main products of Cisco, designed for data centers. On this day, there was a family of Cisco’s virtual network switches. Five years ago the Nexus 1000V virtual switch is a pioneer in this market. Since then, the Nexus 1000V installed more than 8,000 customers. An increasing number of implementations of this switch to other platforms, such as Microsoft Hyper-V. In the near future it will be compatible with the Linux / KVM. To date, the Nexus 1000V became the most popular in the industry software networking solution based on the controllers, that is the solution for software-defined networking SDN.

Each quarter, Cisco appear in hundreds of new customers who purchase the paid version of this product, even though the market it is available free Basic version with full functionality. Interest in the virtual network solutions is growing steadily since the early days of the appearance of SDN solutions on the market. In this situation, the virtual Cisco networking solutions have become a favorite target of the myths and unfounded rumors. It is time to expose these myths.

Myth 1: Nexus 1000V – only virtual switch

first Nexus 1000V distributed virtual switch was (vSwitch) for medium VMware vSphere. Today, it has become a better industry platform for cloud computing and services, allows you to scale (using VXLAN) virtualization solutions for multi-user networks operating with different gipervayzerami.

Nexus 1000V became the industry’s first platform with the functions of chaining services, call forwarding services and unloading services using technology vPath. Until now, Nexus 1000V is the only such platform available on the market. Version of the Nexus 1000V Advanced Edition includes a specially designed firewall Virtual Security Gateway, interacting with the attributes of the virtual machines. Range of virtual services Nexus 1000V built up with the help of solutions such as Cisco Cloud Services Router (router cloud services), Citrix NetScaler 1000V (application delivery controller), vWAAS (a means of accelerating the work of global networks), ASA 1000V Cloud Firewall (cloud firewall) and Cisco Prime vNAM (means of analysis and network monitoring).

Nexus 1000V allows in safe mode to expand the private cloud, or a physical data center, transferring some of their functions to external providers of cloud services through solutions Nexus 1000V InterCloud keeping all internal Policies and virtual services in a public cloud. The broad functionality, covering almost all network layers from the second to the seventh and including the integration of hybrid clouds, makes the statement that the Nexus 1000V, they say, no more than a virtual router, completely unfounded.

Myth 2: Nexus 1000V does not support virtualization of network

Cisco developed technology VXLAN and in August 2011, made it available to industry partners that allowed the development of an open standard IETF. The frame format L2-LISP has become the standard for frames VXLAN. Today technology VXLAN widespread in the industry and was the basis of the best solutions for network virtualization. Nexus 1000V has become the industry’s first platform to support the decision VXLAN (from January 2012). Now Cisco planiruen support solutions with technology NVGRE environment for Microsoft Hyper-V.

Nexus 1000V was the first platform to the gateway VXLAN-VLAN, supporting interoperability between the physical and VXLAN segments VLAN and full compatibility between the physical and virtual workloads and infrastructures.

Nexus 1000V first proposed improvements for the standard IETF VXLAN, including the ability to implement without multicast. Nexus 1000V is scalable and can support more than 16,000 segments VXLAN, thousands of renters and 32 thousands of virtual machines on each pair of virtual supervisor modules (Virtual Supervisor Module, VSM).

In June 2013 took place on a Orlando (Fla.) Cisco Live conference Nexus 1000V switch showed expansion VXLAN for couples VSM using the protocol BGP. This solution is highly scalable and can support thousands of hosts.

aforementioned record-breaking achievements show that the Nexus 1000V – the best available on the market of virtualization platforms, so the myth number two, too, has no basis.

Myth 3: Nexus 1000V is not intended for automation

first Nexus 1000V intended for network administrators, and so from day one supporting a familiar command-line interface NX-OS interfaces and XML / netconf. Some customers still use these interfaces to control the decisions of Nexus 1000V. But since then, the platform has undergone major changes, having included the interfaces REST API, designed for automation, as well as technology, Power Shell environment for Microsoft Hyper-V. In addition, Nexus 1000V integrates well with a variety of management platforms such as VMware vCloud Director, Microsoft SCVMM, OpenStack and Cisco UCS Director. Finally, Nexus 1000V integrates with the decision of Cisco Data Center Network Manager (DCNM), simplifying network management data center. Another myth burst like a soap bubble …

Myth 4: Nexus 1000V tightly bound to the hardware Cisco

Nexus 1000V is running Cisco NX-OS, one of the most popular operating systems for data center networks. As a result, the customer receives a consistent functionality and stability. A large installed base of Nexus 1000V shortens training, as this product is well-known to most modern network of professionals. Thus Nexus 1000V can be set independently from the physical Cisco Nexus switches and Cisco UCS servers in any infrastructure and network of any vendor. Architecture recently announced Dynamic Fabric Automation (DFA) and Application Centric Infrastructure (ACI) distinguish from normal Nexus 1000V virtual switch. Integration with solutions from other vendors makes Cisco the only supplier able to offer a truly integrated network solution for the data center, including both physical and virtual components.

Now let’s see why the Nexus 1000V is the best platform virtual switching for network services at the levels of L3-7.

First, Nexus 1000V – the only platform that truly works well in an environment with a lot of different gipervayzerov. Nexus 1000V supports a consistent functionality for all popular gipervayzerami, including ESX, Hyper-V and KVM / Xen.

Secondly, Nexus 1000V supports the most advanced functionality needed for enterprise customers and cloud operators, including VXLAN including advanced features and innovative technology connectivity services vPath;

Thirdly, it is the only cloud networking platform, providing seamless integration of physical and virtual services under a single operating model that supports the transparency of all network functions and a single diagnosis.

There are two versions of the switch Nexus 1000V. Free basic version (FREE Essential edition) includes all the features such as VXLAN and vPath, necessary for the cloud network environment of high level. Download this version here. An enhanced version (Advanced edition) includes additional security features, as well as free licenses for firewall and Virtual Security Gateway gateways VXLAN-VLAN.
