VMware NSX integrates networking into the virtual world. It also brings networking services to the in a distributed and much simpler fashion. One of those network services is load balancing. Using NSX, you can create virtual IP addresses which routes incoming network traffic to multiple real servers.
It works just like your regular hardware load balancer (F5, A10 Networks, etc), but in a distributed way and grouped by real servers on your computing hardware.
Making these network services virtual, means being able to deploy it very rapidly and easy. So easy, you can create a web load balancing cluster in … Read more
VMware has released a design guide for a network with NSX, Cisco Nexus 7000 and Cisco UCS computing. Perhaps it’s a small glueing attempt from VMware to Cisco, maybe it’s nothing. The thing is, I’m really happy about this design guide, there’ll be a FlexPod for NSX yet! 😉
One of the good guys, Hany Michael over at hypervizor.com, has made a few videos showing the installation ease of VMware NSX. Unfortunately us normal peasant people do not have access to NSX yet, but you can see how the installation goes. Check these out:
This article is number two of a series about the upcoming network virtualization spree, specifically the one coming from VMware. Check out the other articles.
Traditional network services have evolved over the last years. Introducing more advanced firewalling, loadbalancing and remote access services. Typically, datacenter networks architecture these days look somewhat look this:
The routers can be virtualized inside a physical box, using either VRFs or vendor proprietary router virtual routers, such as Cisco VDC. However, the external and internal firewalls are usually separate monolithic hardware firewalls, which puts a large dent into the network budget.

I spent 14 to 17 October at VMworld 2013 in Barcelona, basically getting my mind blown by the futuristic possibilities of network flexibility. Things are changing for the network, flattening the entire stack, distributing network services throughout the virtual network (instead of the monolithic central hardware), lowering network costs and making it more flexible and simple to manage.
In this post, I will go over the basics of the components that are used to form the VMware NSX virtual network.… Read more
Today I had the need to remove the VLAN ID from 60 ESXi 5.1 hosts. Instead of doing it 60 times manually through the KVM, PowerCLI was enlisted for the job. That wasn’t the hard part, the one-liner is quite simple..For those interested:
When using the “Simple Install” to install a new vCenter setup, you might encounter the following error when trying to register the vCenter server to the Web interface:
The vSphere Web Client Administration Tool only supports registration of vCenter Server version 5.0. For newer versions, the vCenter Server system must be registered with the Lookup Service to allow the vSphere Web Client to discover the system.
To resolve this, follow these steps:
Log in to the vSphere Web client as the admin account (admin@System-Domain) you created during the vCenter server installation
