As I start to use more and more Photon OS for smaller workloads and test scenarios I thought it might be good to collect some quick commands etc. which I constantly use had to research first. This will include standard network setup, the usual tools etc. If you miss anything let me know, happy to add something to the list.

Designing and deploying a multi-tenant public cloud is no longer complex with VMware Cloud Provider Pod. Learn how you can modernize your cloud provider infrastructure with an automated design and deployment of the VMware Cloud Provider Platform.

As I wrote in a previous article I have to deal more and more with CentOS 7 and the use of the network manager and in special the network manager command line interface or short nmcli. I will use this blog page to create a little cheat sheet for myself with the most common commands I use and hope this can be helpfull for others as well.

It has been quite a while since I needed to create a CentOS based NAT router and with all the changes in network configuration with CentOS and RHEL 7 it took me a while. Normally most I deal with is either core router or NSX based (DLR or ESG). So I decided to do a little writeup...I used the CentOS 7 minimal installation to start as I want to also reduce the attach pattern.

For a project I currently work on we had to create a mobile rack with ESXi hosts. After some research I found that the SuperMicro E200-8D are actually a good choice for the case. They have 4 NICs (2 x 1GBe + 2 x 10GBe) plus a seperate ILO and support NVMe and SSD as a parallel disk option. If you choose these servers you need to be aware that the necessary intel drivers for the NICs do not come with the VMware base image. You need to download and install them.

It’s this time of the year again where a lot of us need to decide. Shall I go to this year’s VMworld?

Sometimes vSphere AutoDeploy is not possible, like for an initial deployment or other reasons. In this article I described how to setup a bootserver for generic ESXi install, but also how to autoinstall an individual host.

Two weeks ago I had the pleasure to spent 4 days on problematic Applications within an App Volumes environment of a customer. The best thing that can happen to me as an infrastructure guy is to work on building AppStack with guys who know how to package and therefore troubleshoot those applications

Over the last months I gathered more and more experience about VMware’s secure Linux appliance that allows secure access to a virtual Desktop (and more) over an unsecure network (e.g.) the Internet: Unified Access Gateway (UAG). Keep in mind the UAG is not just a replacement for the old Windows based Security Sever, it is also offering much more functionality (Edge Services for Airwatch / Workspace One, reverse proxy, 2nd-factor authentication integration, etc.).

I love the vCenter Server Appliance. The migration works pretty well. Still from time to time I stumble across minor problems (which until now were always quite easy to workaround/fix). One of this migration ‘issues’ I was faced with recently at a customers site.
