Marcel — Tue, 09 Aug 2011 18:15:11 +0000

As a more and more Server-, Storage- and virtualization engineer I’m more then exited to see that Cisco is evolving there Cisco UCS platform with 3 more new products which I received in a marketing e-mail from Cisco. New Fabric Interconnect (Cisco UCS 6248UP) that doubles the switching capacity of the data center fabric to [...]

DnsShell for Windows PowerShell

Marcel — Mon, 08 Aug 2011 12:03:00 +0000

A while ago I created a simple script to create some DNS records using dnscmd.exe. This because there where no DNS cmdlets for PowerShell available. Although it worked fine for me, I can imagine people would rather using PowerShell cmdlets. Nowadays they are available for download yet pretty hard to find. I haven’t used them [...]

My journey to the private cloud

Marcel — Fri, 13 May 2011 10:02:51 +0000

Well, it’s been a while since I wrote a new blogpost mostly due to the lack of time. If I look back at the last 6 months or so there where some heavily private issues, but also a lot of studying into new products. So what happened lately besides my personal problems….? Starting from the [...]

Don’t forget the RFC’s!

As one of the long term moderators at the Petri website I often see questions which could be easily found or answered. A lot of these questions are regarding protocols such as FTP, HTTP or DHCP. I know for sure that the vast majority of IT professionals are already aware of this and I’m sure [...]

Migrating FSMO Roles Within ISA or Forefront TMG

Marcel — Fri, 03 Dec 2010 22:45:21 +0000

Like Microsoft ISA server, the Configuration Storage Server (CSS) from TMG also uses ADAM to store the configuration. When creating a replica of the CSS, ADAM is also used to replicate the data. But what if the primary fails and you have to reinstall the server? Well, in that case you can still use the [...]

Firewall Clients Aren’t Balanced When Using NLB Array

Marcel — Thu, 02 Dec 2010 19:12:19 +0000

Recently I came across something interesting when building a new ISA environment where the Firewall Client will be mostly what is used. Almost all the traffic needs to be authenticated before being sent to its destination. Since the Firewall Client is designed for that (the traffic is not just HTTP(s) and FTP over HTTP) we [...]

Locking the iPad’s Screen Orientation in iOS 4.2

Marcel — Tue, 23 Nov 2010 22:09:24 +0000

This is something a bit different from my regular posts but since it annoyed me greatly I thought I should write about it. I’m using my iPad quite often, especially for browsing the internet, sending emails and reading a lot of my study books. Really it’s a lot of pages. Also I’m using it often [...]

Solving the Error “Could not format a VMFS volume” When Using Nested ESX in VMware Lab Manager

Marcel — Fri, 12 Nov 2010 13:58:38 +0000

While building some basic VMware Training I thought I needed a lab environment for my colleagues to test things out. For this I simply created an empty VMware Template in ESX and I imported this template into VMware Lab Manager (did I already said that I love this product?). So After creating a basic environment [...]

Cisco UCS Emulator

Marcel — Fri, 05 Nov 2010 22:42:17 +0000

A few months ago I was certified for Cisco UCS Implementation. In our lab environment we are currently busy connecting and setting up our test UCS environment. However, just a few minutes ago I found a tool that is incredibly useful and I only wish I knew about it earlier. I just found a Cisco [...]

VMware Project Onyx

Marcel — Wed, 03 Nov 2010 17:24:46 +0000

Today I heard something about Project Onyx from VMware. Although I just started playing with it today, I thought it was so interesting that I needed to write something about it. First of all, Project Onyx is a little tool which can help you to automate certain processes without having a large amount of PowerCLI [...]
