Linux Foundation Certified Systems Administrator (LFCS) Exam Review #LinuxFoundation @linuxfoundation #Linux #CentOS @sandervanvugt @tecmint #vExpert

December 18, 2017 Bilal Ahmed 0

So I spent a good few months brushing up on my Linux skills for this exam. Where I work there is a big proportion of VMs that run CentOS 6/7 and with all the other studying I had been doing, I had never had the time to improve my Linux skill set and it has always been an area that I was lacking in. The reason I went with the Linux Foundation is because they had a black Friday sale on last year where you could get the course and the exam (with a free retake) pretty cheap. My company paid for it and all, but it just seemed like a no brainer . You can pick from multiple distributions, […]

Resizing VMDKs with vSphere Replication #vExpert #vSphereReplication

December 12, 2017 Bilal Ahmed 0

*picture from VMware docs Now then, everyone that has used VR knows that resizing VMDKs for replicated VMs isn’t the easiest thing to do. But I have come across people who seem to believe that the only way to resize the VMDKs is via the CLI on a host….this is one of the options BUT IS NOT the only one. Resizing via the CLI: https://kb.vmware.com/s/article/2052883 > No need for me to repeat what it says, but you do it using vmkfstools. It works well but does require the person to have access to the host directly. The key point when using vmkfstools , which isn’t totally clear in the kb is: If the original size was 550GB and the new […]

Lets Talk About Sexigraf @Sexigraf_fr #Sexigraf #Monitoring #vExpert

October 9, 2017 Bilal Ahmed 0

So I went to my first VMUG recently and it was great! I met plenty of new people and learned a lot of new things. I got in a few discussions about monitoring and I mentioned that I was pretty fond of Sexigraf @Sexigraf_fr . I found it interesting that a few people had never heard of this great FREE product. I mean monitoring is important, whether you want to know what your cluster utilisation is or how your datastore latency is or how your VSAN cluster is doing. Keeping stats for a period of time is also important because you want to be able to monitor trends etc. There are plenty of products out there that can help you […]

How to configure different networks in Ravello – vEXPERT

October 7, 2017 Kim Bottu 1

Intro As a vEXPERT I am entitled to a cloud lab provided for by Ravello Systems. By default this lab has been setup on a specific network: 10.0.0.0/16. Until today I have been placing all my objects on my canvas on that same network. Below you can see an example of that. When I take a deeper look in the network configuration of Ravello I can see that the following has been pre-configured for my convenience: A switch: Switch 1 A router: Router 1: 10.0.0.2 A DNS server: 10.0.0.1 A DHCP server: 10.0.0.1 A DHCP range: 10.0.0.1 – 10.0.255.254 A Gateway: 10.0.0.2   FreeNAS –  double interfaces Today I finally took the time to make some changes. As an example […]

VMworld 2017 – A bold and strong statement

September 15, 2017 Kim Bottu 0

There is no denying it, I am a bit disappointed because there haven’t been any major new technical announcements apart from HCX at VMworld Barcelona and the technical geek in me craves them. But I don’t want you to think that there was no big news. Actually, the opposite is true. VMworld 2017 sends out a clear message into the world. VMware has turned its back on the path of the technical wanderer who tries to redefine himself by trying to play catch up with the big technological buzzwords -such as containers, Kubernetes, AWS, Azure, Google,cross-cloud and micro-segmentation – and instead baffles the world with an enterprise ready eco-system which uses all of the buzz word technologies and offers access […]

VMworld 2017 – Day 3

September 14, 2017 Kim Bottu 0

On day 3, Pat Gelsinger, Ray O’ Farrell and Sanjay Poonen started off with replying some questions the audience have. Questions about a simplified model for licensing which might include NSX (the short answer is that they like to keep NSX licensing seperately for now)   the readiness of the HTML5 client (the HTML5 client contains nearly 90% of the available functionality now), had been answered. Credit was given to the open source community and Pat confirmed VMware’s continued involvement and will continue to invest in Open Source. VMware really appreciates the community that drives the Open Source. In fact there is a department in the Office of the CTO which focusses on engaging with the open source community more […]
