Recently there are many confusion about these new terms VN-Link & Cisco nexus 1000V which been widely communicated to the IT user groups. Where were the confusion come from? Most of the time, we are getting confuse about what is VN-Link meant by Cisco. Below is some short description you may want to refer to.
Cisco Nexus 1000V is a enhance virtual distributed virtual switch which integrate to the VMware vSphere 4. With Cisco Nexus 1000V, you will contain VSM and VEM, which VSM will be the virtual appliances that host the management of Nexus 1000V, and VEM will be installed on each ESX host that been connected to the Nexus 1000V. I will not go in too details about Nexus 1000V in this post as my intention is to clear up the confusion on the VN-Link meant by Cisco.
VMware had done the best job since they introduced vmotion and cold migration which allow us to move the state of the virtual machine from 1 Host to another with or without down time. In virtualization, it encapsulated the entire Server into the virtual machine format and it is hardware independent. Therefore you can always move from 1 host to another without having re-install or reconfigure your operating system or application.
Well, since we had achieved this in virtual environment, what about physical environment?
If you had previously installed, configured or an existing users of Cisco UCS, you may be excited with the latest firmware release from Cisco for the Unified Computing System. I had personally upgraded the firmware and tested with all the functionality, it looks much more better compare to the version 1.0. I will encourage most of you to consider the firmware upgrade which it significant enhance the interfaces and functionality for the Unified Computing System.
The new interface for the KVM also included the button to boot, reset and shutdown the server.
Today I was setting up the Nexus 1000V with Cisco UCS, and this was my 2nd time of experiencing the nexus 1000V. Previous experience when I did the 1st installation and configuration on Nexus 1000V, it take me few days to get it done, but it only took us 1 few hours to do so with a help from my colleague who are the networking expert. I was using the Nexus 1000V version 1.2 which is greatly enhance and simplify VS the version 1.
