My ramblings about all things technical

All Things Virtual 21

I have been slacking on my All Things Virtual postings for the past few months due partly to me just being a bit lazy if I’m honest and due to my focusing a lot of my spare time after work on my EMC and VMware studies(blogs forthcoming). Due to the rate of new blogs coming out and things changing so fast, a large portion of the blogs I had on my list of things to read and thereby be in line to be included in this posting have now become obsolete/old news so my list was culled and is now a current as is possible.

First thing is a little bit of a plug of my VCAP-DCA & DCD resources page and a big thanks to a few people who have helped it gain so much traffic/views. The page has been receiving an overwhelming amount of views(at least in my eyes) and this is mainly down to many of the top people in the virtualisation industry very kindly pointing to it in their blog postings about the exams. So a big thank you to

Speaking of the VCAP exams and preparations for it, I was fortunate enough to attend the  VMware vSphere: Manage for Performance Course and wrote up my experiences of the course for anyone thinking of attending the course. One of the topics of conversation was how the impact of virus scans in your virtual environment can impact the performance of your environment drastically especially if all your virus scans kick off at the same time. Richard Garsthagen has posted a brilliant little blog posting this week all about Security designed for virtualization and how Trend Micro’s new product DeepSecurity 7.5 is using the newly available EPSEC API to save you having these performance hits and has added the performance benchmarks to prove. it

Next is the announcement of the soon to be released and much anticipated PowerCLIBook by industry experts Luc Dekens,Alan Renouf,Arnim van Lieshout, Glenn Sizemore and Jonathan Medd. For anyone remotely using PowerCLI they will know these guys are some of the best if not the best in the industry when it comes to PowerCLI and so this book is being tipped as the perfect book to use to teach yourself everything you need to know about using PowerCLI in the VCAP-DCA exam and to obviously help you build up your knowledge before the release of vSphere 5(or whatever it may be named). I’ve already pre-ordered my copy and will be using this book cover to cover before my VCAP-DCA exam and to teach myself PowerCLI.

Eric Horschman has done a brilliant posting on the VMware Blog pages all about Hypervisor Memory Management Done Right which is  brilliantly written and a perfect reference article for memory management and how it all works and what the kinds of impacts mismanagement can cause in your virtual environment. I’m still slowly reading through it myself and trying to apply some of the best practices into my own environments.This posting is a MUST read for anyone looking after a VMware environment or looking to build one.

The VMworld Europe dates and venue have now been announced and you can sign up to be notified when registrations open for it and the US event. I was very fortunate to attend last year and hopefully I’ll be approved to attend again. My aim this year (a rod for my own back comes to mind at this point) is to try have a session approved for VMworld Europe this year and to present it at VMworld Europe. I’ve decided to do this as I feel it’s a good thing to aim for seeing as the people I look up to in the industry and who I would like to be one day are obviously people who are doing these kinds of sessions and it will hopefully push me to try be a better presenter and hopefully advance my knowledge and skills. Now to just think of something to do for my session…

As I said at the start of this posting I’m busy doing some EMC studies and to not get into specifics seeing as I’m a bit superstitious and I’d like to save it for my planned blog posting one of the reasons for doing it is to hopefully prepare myself for the recently released EMC Cloud Architect certification. Chuck Hollis from EMC posted this past week an update for the certification detailing that the courses are now in full production and has linked to a few testimonials of people who have already attended some of the courses. The courses look really good and even if you feel cloud is just a buzz word at the moment I’d still encourage you to have a look at the certifications and Chucks blog postings about them before writing them off.

Scott Drummonds posted a twitter message this week asking for help finding whitepapers on the subject of VMware environments networking best practices. True to form the community responded and Scott has blogged about all the resources he was pointed to. It’s a great resource for all the VMware networking “best practices” and will prove to be a time saver for anyone needing to source this information for VMware builds. I’ve added it to my “VMware Design Best Practices” bookmarks already.

Last but not least is a blog posting by the infamous Duncan Epping of Yellow-Bricks.com fame all about managing the availability of your environment through vCentre alarms. I blogged a while back all about a document created by Horst Mundt a Technical Account Manager at VMware Germany on the VIOPS.VMware.com site detailing all the alarms and what they do in vCentre 4 and vCentre 4.1. Both are a definite must read especially if you aren’t currently using custom alarms in your environment. My favourite one at the moment is an alarm to alert you when snapshots get over a certain size which has saved me loads of headaches. There’s a great VMware KB article all about how to set this alarm up and even includes a very helpful video if you’ve never done custom alarms before. 

Well that’s my list of things that have interested me in the last week, for those people writing the VCAP exams soon good luck
