January 7th, 2010

As Alessandro Perilli has written in his article [1], parts of the IT industry expect 2010 to be the year of cloud computing (the other parts expect it to be the year of VDI ;-) [2]).So it is time to think about what cloud computing is right now, what it can be and what it is expected to be…

Cisco Nexus 1000v, SC-Ports, VMkernel-Ports and more

The biggest benefit is that you can give control of the network-ports, your VMs are plugged to, to your network administrators – They truly can handle all the VM-Ports as physical ones (but they have to know how to handle cisco switches). Furthermore you can let the vEth-Ports move with the VMs from host to host.

How-to setup a high-performance test-lab on a laptop…

September 26th, 2009

Therefor I’ve written a little how-to, which can be downloaded in the articles-section. The two good things about this kind of test-lab are:

  • it is generic and can be used for every Windows Server product
  • it uses only little space and combines the io-performance of two harddisks


Have fun…!
