My ramblings about all things technical


VCAP-DCA & DCD Resources Page Updated

Just a very quick posting to alert people that I have now updated my VCAP-DCA and DCD resources page. The page is a list of resources that I have been constantly updating as I  have come across new resources and I have made my way through the  required amount of studying to be prepared (which is still on-going).So either click the “VCAP-DCA & DCD” link at the top of the page or click here if you can’t be bothered going to the top of the page and if you know of any other great resources please do comment so that I can add them and it can benefit the whole community.

Also a reminder that Kendrick Coleman is doing a VCAP-DCA Live Lab on Cody Bunch’s Brownbag tonight so go to his site and register as it’s sure to be a brilliant one



All Things VMworld Europe – Day 2

Day two started off early as I decided to not hit the massive parties so that I could get into the labs as they opened at 8am. The Bella centre was empty and I was one of five people in the labs at opening time. I went to the VMware vSphere PowerCLI lab and got a really good foundation of PowerCLI commandlets and it was a great starters lab for a point and click person like myself.

I then made my way around the solutions centre and spoke to Alan Renouf about the lab and all other general things and got a great picture of him at the booth.I then hung out with a number of the top bloggers at the bloggers lounge and got to meet John Arrasjid (@vcdx001),Bas Raayman (@BasRaayman), the vNinja Christian Mohn (@hobbel) ,Steve Bruck (@vColossus) and the Chad Sakac (@sakacc).

Next on my schedule was Kendrick Coleman and David M Davis’ Ten Best Free tools for vSphere. The session was packed but I had made my way in early so ended up being in the second row due to them not allowing you to sit wherever you wanted. The session was brilliant and seemed to go down extremely well with the audience. I would highly recommend you check out Kendricks Top 10 Free vSphere ESX Tools and Utilities posting here and have a try with all the tools as I use a large amount of these tools already and they are brilliant and will make your daily role a lot easier while not costing your department anything.Also go vote for your top ten free tools of 2010 on David’s blog here.I also managed to nab myself a vNerd shirt from David Davis from his employers Trainsignal. Yes it’s sad I really wanted a shirt saying vNerd but I love it 🙂

I then attended the Project Horizon session which was really informative and the concepts covered were really exciting but obviously due to it being in development still the talk wasn’t vastly different from what was covered in the keynote yesterday morning. I’m hoping to get myself some more hands on experience of the product once it is available as the the product does look to be one that is going to become massive with all it’s features and the push of people to be able to do their work through iPads,iPhones and Android devices.

From there I made my way to a VMware vSphere Troubleshooting lab which was highly informative and the best lab I had done yet as it was great to test my own troubleshooting skills and learn a few new ones/perfect them. It was also very refreshing to work on an environment that was broken yet not mine as then the obvious pressure you normally have wasn’t there 🙂 The lab was also a great introduction to the official course being run and I’m looking forward to doing the course and learning all of it.

From here I had to catch up with some office work and then made my to the VMware Party. The party was really impressive with great food, loads of drinks, some crazy performers from circus performers to break dancers and then the bands Bjorn Again (an ABBA tribute band) and MADHEN (the house band). ABBA had broken up before I was even born so I enjoyed playing table football (foosball) against some VMware employees more than the bands but I do have to say the crowd was absolutely loving them and my wife and parents would have been front row of the performance.

Due to my wanting to get into the labs at opening time again I left around half eleven. The second day was really great as I got a good amount of time with fellow bloggers for some knowledge transfer,the sessions to learn the new products and features and the labs to be able to play around and gets some hands on experience of the new products and strengthen my knowledge on technologies I have been using for a while.

All things virtual VI

It’s definitely been a very hectic past few weeks for me and due to this it’s taken me quite a while  to get this posting to a post able standard. There has been some brilliant articles and news in the virtualisation arena and some resources that are currently and will in the future help me to make my daily job a lot easier.

First is one that i think is a common mistake among many people when they plan/build their VMware virtual environments.Craig Risinger has posted a guest posting on Duncan Epping’s yellow bricks website all about resource pools and how people need to keep an eye on the amount of resources allocated to a resource pool compared to the amount of machines that are in the resource pool. It does seem a very obvious thing to monitor but I even had to run an eye over the ones in my environment as with the amount of migrations and builds that happen it’s something you forget to check or amend.

Next is a great article I found when trying to explain blocks sizes to a fellow IT friend and about alignments and what both are and what you need to think about in your decision of aligning your data or not. Steve Chambers (@stevie_chambers) wrote the article and is one that I learnt some more from as well as helped me to refresh some of the knowledge i knew but due to not having used it for ages had forgotten some of.

Another posting is stumbled across these past few weeks that caught my interest was a posting by Ian Koenig all about IO DRS. This is a fairly new idea to me as I’ve obviously always done cpu and memory DRS as it’s standard to monitor and make changes dependent on vSphere’s DRS clusters settings but Ian has done a very intriguing and exciting posting all about IO DRS and how it could come very soon to allow you to monitor and make changes dependent on IOPS and details how it would all work. I then did a bit more research on the topic and it seems I’m not alone in my interest and excitement about this feature. Rich Brambley (@rbrambley) wrote a blog posting all about it and detailed some of the things that were mentioned about it at this years VMware Partner Exchange.

Fellow Saffa , Rynardt Spies’(@rynardtspies) has written up a very detailed and thought provoking posting all about VMware vCentre 4 Design Considerations and has given all the pro’s and cons he took when deciding  32bit or 64 bit, physical or Virtual and placement of the vCentre database as well as the Update Manager Server and database.

Simon Seagrave (@kiwi_si) has done a very clever and interesting 5 minute video reviewing vkernel capacity view and how it works and looks.  An application I haven’t tried myself but a it’s nice to be able to get a quick run through of what it is and does.

The infamous Eric Sloof (@esloof) posted up his vmClient last week. the tool looks amazing is something everyone needs to have a try out of as it has helped me tremendously by allowing me to quickly jump between virtual machines while trying to do loads of things at once. He’s also done a great video run through of how it looks and works

While listening to the VMware Communities podcast about ESXi last week I was reminded of the latest release by trainsignal the VMware Pro Series Training Vol1. As i mentioned in my posting about the resources i used for my vcp4 exam, the trainsignal videos are priceless in your studying and preparing for the exam as well as a very helpful tool if you need to refresh your knowledge on things you may have become rusty on. I’m planning on getting my hands on this latest instalment but if Kendrick Coleman’s(@kendrickcoleman) twitter and blog posting about it are anything to go by it should be brilliant.

Vladan Seget has posted a great little posting on how to add a second service console via cli. This caught my attention firstly because I’m personally trying to do more and more via vma and cli to prepare myself for ESXi as well as very good troubleshooting step by step.

David Convery has done a very interesting posting all about the problems he encountered with his vshield zones and the ways he got around them. I’ve been planning to implement vshield zones into my home lab for a while but haven’t got around to doing it yet, so David’s posting is now one of the pointers and steps I’ve added in my implementation of it.

Over the past week there has been a major buzz all about the release of simdk. Andrew Kutz(@sakutz) is the man behind this creation and what a little creation it is. Andrew has managed to create a VMware vSphere4 simulator which provides vSphere4 API-compatibility. I’m seriously excited to get it implemented and deployed in my lab environment as it should allow me to get so much more of my testing done and hopefully will save me some money in my VCDX lab deployment. I’m also keeping my eye on the official site of the product for any news and update.

Lastly one from my daily troubleshooting. While migrating machines to new hosts we noticed that certain machines network cards were unticking the connected radio box in the vm’s settings


Even if we ticked connected and applied the changes it kept on reverting back to being unticked. My colleague Simon Phillips noticed the solution, that we had created the vSwitches with the standard 24 ports and therefore once we had reached that number of ports used there were obviously no more spare ports and so the machines couldn’t be connected. There were no errors telling us this was the problem but it’s a very good example that early simple planning and configuration would have fixed.
