Cisco Nexus 1000V

Brad Hedlund из Cisco Systems в своем блоге опубликовал некоторые подробности о новом продукте, замене стандартного vSwitch на ESX 4.0. Nexus 1000V пока из беты не вышел, но было бы странно его зарелизить раньше, чем VI4. Скорее всего это будет сделано одновременно.

А пока схема работы Nexus 1000V

• The Nexus 1000V software on the physical server acts like a line card of a modular switch, described as a VEM (virtual ethernet module)


• The Nexus 1000V VEM is a direct replacement of the VMWare vSwitch function


• The Nexus 1000V VSM (virtual supervisor module) acts like the supervisor engine of a modular switch


• One Nexus 1000V VSM instance manages a single ESX cluster of up to 64 physical servers


• The form factor of Nexus 1000V VSM can be a physical appliance or a virtual machine


• The network administrator manages the Cisco Nexus 1000V (from the VSM) as a single distributed virtual switch for the entire ESX cluster


• Each virtual machine connects to its own Virtual Ethernet (vEthernet) port on the Nexus 1000V providing the network administrator traffic visibility and policy control on a per virtual machine basis. Virtual machines can now be managed like physical servers in terms of their network connectivity.


• The network administrator defines Port Profiles which are a collection of network configuration settings such as the VLAN, any access lists, QoS policies, or traffic monitoring such as NetFlow or SPAN.
