The last and first week of the year I normally reserve for some jobs around the house, some time with wife and kid and some studying. This time the VCP5 exam was the goal. I combined this with the update of my vSphere4 administration and advanced administration course I give for Ictivity Training. This way [...]
While preparing for my VCP5 exam I was reading a lot of material including the upgrade guide. As with all upgrade, not all upgrade paths are supported. That’s why I thought to make a list with some upgrade considerations. vSphere5 only comes with the ESXi hypervisor architecture. The main distinction is that ESX comes with [...]
“The server has poor performance because the server is running virtual.” “Virtual server are always slower than physical servers.” “My vSphere server has 60% CPU utilization but the performance of my Virtual Server is poor.” When you are a VMware administrator you constantly have to defend your self that it doesn’t matter if a server [...]
Even do vSphere is telling you that the overall CPU utilization is no more than 60%, this doesn’t indicated that your VM isn’t running low on CPU resources. In this part where going to deepdive in troubleshooting CPU performance related issues on your vSphere environment. Although I’m using vSphere 5.0 for my screenshot, most of [...]
Just a quick post about something I noticed while configuring a new vSphere5 host with a Broadcom iSCSI Adapter. This is not a real iSCSI HBA but a vmnic with TCP/IP offloading. This offloading feature benefits the performance of iSCSI because the vmkernel doesn’t have to do as must work as with a normal vmnic [...]
One more day of work and than after the weekend I’m flying to Copenhagen. Off to VMworld 2011. I’m really excited this year. A lot of great new stuff has been released (vSphere5 and all of its features, View5 etc). So I’m expecting a lot of great session and meet-ups with some people in the [...]

It has been a while when I wrote part 2 but I’ve been really busy with vSphere5 that I didn’t had the time to complete my series. But now part 3 of upgrading my home vSphere 4 cluster to a vSphere 5 cluster. In this part where going to upgrade my 2 ESXi 4.1 server [...]
Although I’m not the biggest fan of programming and there fore PowerCLI, with vSphere5 you cannot do without it. So, if you want to create a small PowerCLI script for daily tasks this reference card can come in handy. Want to know more about PowerCLI? Follow @alanrenouf
