Yet another role added to my Job description, Now I am managing our Virtual Servers. So true to form I’ve dived headfirst into powershell / powercli to see what I can do. Some of the posts coming up on this will likely be similar to others around the web as I reinvent the wheel while I learn. But you never know one of you might find me 1st or I might do it in a way that suits you better.
First up is a simple script to read data from an xml file and then update custom attributes on the vmhosts.
Small shell script that returns the details in /proc/cpuinfo in a more human readable and relevant way.
Sample output
Processor seems to be quite old guessing number.

This section contains the scripts I use to quickly redeploy the nodes. The “Post Script” could be improved a lot and also made more generic, however I’ll leave that as a task to the user, I may update it at some point if I have a need.
Welcome to part 2 of the series. We will cover sett ing up 3 vlans for the tcp/ip network and then we will ensure all the packages for infiniband are installed. Read More
To facilitate testing of our software and so that support can model possible customer environments I was tasked with setting up a cluster with infiniband. I was excited as the system was a Dell PowerEdge blade cluster (our 1st blade system) and we have never used or deployed infiniband (this would be our 1st infiniband system), in fact other than a basic “we have heard of this and know (very) roughly what it is” no-one in the group had any real knowledge of it. After a few hours of searching the deepest recesses of the Internet I had a limited understanding of how to setup the system. I know how irritating it is to have to read the crud in order to find that wee gem of info so from here on I’ll mark the paragraphs of the article so those of you wanting to “just get it done” can skip them.
