In my post on sizing up the storage for block size usage, I wrote a script to get the data into a manageable form. This script runs fine from the command line but you probably want to have some sort of trend to analyze.
In ConfigMgr 2007 it is difficult to have a true High Availability (HA) solution. This because it isn't supported yet in ConfigMgr 2007; we must wait for ConfigMgr 2012 for that. There are possibilities however with dividing roles on multiple servers, or install it on a Virtual Machine. Then there will be possibilities with VMware ESX (VMotion) or Microsoft Hyper-V (Live Migration) to create a HA environment. ConfigMgr 2007 is not HA then, but the platform on which it's running is.

vscsiStats is a new VMware tool that helps give insight in disk IOs and latency and stuff like that. It’s a very useful tool but it dumps data in histograms. Using these in Excel is quite a pain because Excel knows histograms (with add-ins) but only one at a time. If you want a graph a whole LUN or other lower level part of the storage over time, you need to reformat the data. And luckily, ESX, like most Linux versions nowadays, comes with a python interpreter. Now I know a lot of different scripting languages but python wasn’t one of them. So I decided to write a small python script to do the reformatting for me to allow me to draw nice 3D graphics of block size over time.
This is part 2 of a quick guide to importing a VM into Lab Manager using Orchestrator. In case you missed it, part 1 is available on http://virtuall.eu/blog/import-a-vm-in-lab-manager-using-orchestrator.
There are a lot of things you can automate in a virtual infrastructure. One of the tools that can help automate the more complex workflows is Orchestrator. It’s free when you have a vCenter and it’s very powerful.
This post is a quick gathering of a few small scripts I wrote with my IT-life's motto: "Never do anything twice"
