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.

Sinds de komst van o.a. Exchange 2007 is PowerShell in populariteit toegenomen. Ik ben zelf ook een enorme fan van PowerShell geworden omdat het mij gewoon erg veel tijd bespaard bij bijvoorbeeld het installeren en configureren van een Exchange 2007/ 2010 omgeving. Hoe langer je PowerShell gebruikt hoe handiger je er mee gaat worden. Zo ontdekte ik pas een effectieve manier om een bestaande configuratie van een Exchange Receive Connector aan te passen. Dit handigheidje wil ik door middel van deze blog post graag met jullie delen.
I had a discussion last week with a colleague about archiving messages in outlook. I have a 7GB mailbox on the server because I never delete mail. That may seem overdone but it has served me well a couple of times in discussions we had. Besides, I see absolutely no point in archiving mail away from the mail server to another store on some fileserver that eventually lands on the same central storage.
By default ConfigMgr 2007 Operating System Deployment (OSD) is deploying in Unicast. Every deployment or software distribution will be bit by bit transferred to the device. With ConfigMgr 2007 R2, and specific configuration, Multicast is also possible. Then you can deploy maybe 50 or 100 devices at a time, without the data (bits) being transferred to every device for itself. It's good to know that you have a few possibilities in Multicast, and it's only working in WinPE mode. So what's the advantage of it, with Software distribution in the Task Sequences?
A few blogs ago I explained some Troubleshooting issues in ConfigMgr 2007, especially foccussed on Windows Deployment Services (WDS). But what to do when the Task Sequence is running, and you get an error during deployment? This blog will help you troubleshooting on that part!

Last month I read at Twitter that someone didn't know that MDT could be integrated with ConfigMgr 2007. For me that was the reason for writing this blog about MDT and ConfigMgr. Yes, it's true that the intregation exists, and I will explain all the possibilities and benefits of it! When you are new with MDT or ConfigMgr, you can combine them for having the best of both worlds. Also with the knowledge you have (MDT and/or ConfigMgr) it will be a lot easier for using it.
