Wartungsfenster Podcast

Ausnahmsweise ein Blogpost in deutscher Sprache. Grund dafür ist, dass Claudia Kühn und ich seit Januar 2022 einen gemeinsamen Podcast rund um den Themenkomplex Datacenter, Cloud und IT ein. Eine lockere Kaminzimmerrunde in der wir entspannt über unseren Job, und alles was damit zu tun hat, plaudern.

On the road to... nowhere?

Its been four month since my last blog post, and the blog frequency was quite low before that. This blog is, to be honest, a giant pile of stuff that has not worked as expected. Okay, some random thoughts or howto’s, but most blog posts are about stuff that failed in some way. That’s a bit “depressing”. I should write more about the fun things in my life For a pretty long time my focus was on infrastructure.

Exam prep & experience: Citrix NetScaler Advanced Topics: Security, Management, and Optimization (1Y0-340)

In May 2018, Citrix released their new Citrix Certified Expert - Networking certification, which completet the networking certification path at the upper end (blog post on The track starts with the Associate (CCA-N), the lower-level certification is a requirement for achieving the higher-level certification, continues with the Professional (CCP-N), and ends with the Expert (CCE-N) certification. This is pretty cool, and I’m very happy that Citrix now offers the CCE-N, because the expert-level certification was missing all the time.

What is in the bag?

Michael White published the third release of his “What is in the bag” blog post. In reference to this, I would like to share the content of my bag. I used a RIMOWA Salsa business trolley for several years. Unfortunately, it broke in June 2017 and a repair was refused by RIMOWA. I was very disappointed of the product quality and the customer service experience with RIMOWA. I decided to switch to a backpack, which felt much more comfortable than carrying or pulling the RIMOWA trolley.

HPE Networking expert level certifications

A couple of days ago, I took the HP0-Y47 exam “Deploying HP FlexNetwork Core Technologies”. It was one of two required exams to achive the HPE ASE - Data Center Network Integrator V1, and the HP ASE - FlexNetwork Integrator V1 certification. It was a long planned upgrade to my HP ATP certification, and it is a necessary certification for the HPE partner status of my employer. You might find it confusing that I’m talking about an HP ASE and a HPE ASE.

My tool chain for 2018

Each of us has his or her personal tool chain. Depending on your job role, the tool chain will look different. My personal tool chain does not have changed much over the last few years, but if I added or removed a tool to my tool chain, this change was often influenced by other peoples tool chain. My primary work device is a Lenovo ThinkPad X250 (Intel i5 5200U, 8 GB RAM, 250 GB SSD) with Windows 10.

Continuity vs. change

Note: I trashed this blog post several times. But I would like to express my point of view (hey, this is my blog. :D ) Some weeks back, I had an interesting discussion with a HR consultant. Bottom line: You ruin your career, if you stay for more than 3 years at the same company. IMHO this is bullshit. I have started my IT career, right after school, with an apprenticeship at a local IT company.

Fight the chaos: Design your toolbox properly

You need tools and methods to accomplish your daily tasks. No one will deny this insight. I would like to give you an insight into my box of tools and methods. These tools and methods work for me, but they do not have to work for you. The design of your personal toolbox depends on your job. Depending on who you ask, my job role consists of several roles: Currently, I am working as a consultant, head of the business unit, pre-sales consultant and technical account manager.

Why VARs should rethink their business model

Okay, the headline of this blog post is a bit provocative. This blog post is not written from the vendor perspective. It’s the perspective of someone, who’s sitting between the vendor and the customer. A value-added reseller (VAR) is typically located between vendor and customer. And the business model of a VAR is typically based on selling hardware, software and service. Added value The typical customer doesn’t have the time, money and the know-how to transform business requirements into a bill of materials (BOM).

Solving problems: A structured approach

What is a problem? A problem is an obstacle, that has to be surmounted. Solving a problem is connected with obstacles. Or more general: Problem solving is a process to get from an unsatisfactory to a satisfactory situation. Most of us get paid for solving problems. It’s irrelevant if you are paid for solving technical problem (e.g. My computer doesn’t work), or if you are paid to create solutions for customers (e.
