I had the pleasure to present a session on “PowerCLI and vSPhere Performance and Capacity reporting” during the Dutch VMUG meeting of February 8th 2013. Although the meeting took place in the “Karnaval” weekend, there was a great turnout and, as always, a very attentive and interested audience. Thanks for attending the session guys !
In the session I tried to show how easy it is to produce decent performance and capacity reports about your vSphere environment with PowerCLI. During the session I did some demos to show some aspects of PowerCLI and statistics. This post contains the code, and some annotations, I used during these demos.

Continuing my Dutch VMUG Event 2011 presentation series with a post on the VMFS5 feature. This feature clocked in at position 8 in the Top 10.
With VMFS5 comes a bunch of new features. Just to name a few:
- 64TB VMFS Volumes in 1 extent
- 64TB physical RDM
- Unified block size of 1MB
- Support for more files (> 100000)
For a complete list of the features that VMFS5 introduces, have a look at Cormac‘s post, called vSphere 5.0 Storage Features Part 1 – VMFS-5.

Another post from our Dutch VMUG Event 2011 presentation. This time it’s about number 5 in the Top-10, Network I/O Control. This feature allows user-defined network resource pools and end-to-end QoS.
Note that this feature requires distributed Switches (dvSwitch). In fact I could have also written this post in my dvSwitch series with the title dvSwitch scripting – Part 10 – NetIOC.
The second post originating from our presentation at the Dutch VMUG Event 2011 is about HA. vSphere High Availability appeared in the 2nd place of the vSphere 5 features Top 10. For the HA feature we showed how you could find out the FDM master and slaves in your cluster, and how to find the heartbeat datastore.
During our presentation at the Dutch VMUG Event 2011, Alan and myself showed how several entries of the Top 10 vSphere 5 Features session could be automated with the help of PowerCLI. In the session we showed several demos.
This post is the first in a series, that will publish and document most of the scripts we used for the demos.
On the first position in the Top 10 we have Storage DRS. This feature brings intelligent placement of VMs and storage load balancing based on space usage and IO metrics. See part 4, part 5 and part 6 in Cormac‘s excellent series on vSphere 5 Storage Features.

During my Dutch VMUG event 2009 presentation there was a technical problem with some of the demo videos I prepared. Luckily an audience member came to the rescue by downloading the excellent VLC Video Player via his cell phone. Thanks again for the assistance 🙂
To make up for this technical mishap, the demo videos with a short explanation.
