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 […]

VCAP-DCV Design vBrownbag Section 2.4

March 29, 2017 Jason Grierson 0

Hello, The other day I had the pleasure of taking part in another vBrownbag in the VCAP-DCV Design series with Ron Wedel covering Objective 2.4 – Build Manageability Requirements into a vSphere 6.x Logical Design This chapter has a lot of great information in it around proper design methodology in the Management silo of APMRS (Availability, Performance, Manageability, Recover-ability, and Security) however it sometimes doesn’t really point you towards exactly what the exam will be asking of you. So in this session we covered what the exam will ask of you in objective 2.4 and how objective 2.4 prepares you for your VCDX journey around designing Manageability. Below is the slide deck used in the presentation and the link the […]

WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9 Updated: 03/01/2017

January 3, 2017 Bilal Ahmed 0

So this has been an ongoing saga for quite a while: Repeated VDDK error 1 and 2 This is an issue I blogged about a little while ago too, right here: WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9 It has been causing people plenty of issues and although it’s simple to fix, it’s annoying and it shouldn’t be happening! Veeam and VMware have been pointing the finger at each other for months now. Personally I would lean to it being a VMware issue, simply because a restart of the management agents resolves the issue. So I have been following the thread on the Veeam forums and there has finally been an update! VMware have […]

VCAP6-DCV Deployment Beta

July 18, 2016 Bilal Ahmed 0

So myself and Kim did this exam the other day. Kim hasn’t done any DCA style exam before, and he had a similar experience to me on my first go. It kind of hits you like a train and its a lot to take in initially. The beta signup period didn’t give anyone much time to actually prep for it properly. Having done the 5.5 DCA, I remember looking at some of the questions and wondering what they were wanting……exactly. I did what I thought was correct, you don’t have time to second guess yourself, you just get on with it and do what you can. The best explanation for the DCA/Deployment exam is: Imagine you are a contractor and […]

REVIEW: Architecting EUC Solutions

June 26, 2016 Kim Bottu 0

Each year I order a couple of books even though I have no idea if they will be books which contain content I can actually use. The reasons to buy these books varies: The title might look promising, there is a lot of buzz about a book or it can be as plain and simple as me liking the cover of a book. Brian Suhr’s book belongs to the first category, the title looked promising. Such a strategy can result in picking bad books of course. This book is not a book that does not deliver though. After having read Architecting EUC Solutions I would say this book is quite the opposite to me, an EUC compendium ‘par […]

IT Architect: Foundation in the Art of Infrastructure Design Review

June 15, 2016 Graeme Vermeulen 3

I picked up a copy of this book pretty much as soon as it was released. Most architects I’ve spoken to have recommended this book, so I didn’t want to miss it! Where to start. First impressions The book gets off to a running start, there is no build-up towards hitting you with some great knowledge (the authors have also managed to get a number of VCDXs to answer the question “what is infrastructure design?”). You’ll get stuck in right from the beginning regarding how you should approach solutions design, from the various stages (such as discovery, design, build etc.), design methodologies straight through to really useful case studies. It’s really quite difficult to get this amount of technical information through across […]

Book Review: Networking for VMware Administrators

May 26, 2016 Bilal Ahmed 0

So I have been collecting lots of books ever since I started on my journey of doing my VCAPs. One book time and again has been my go to reference for absolutely anything VMware networking related….and you guessed it…IT’S THIS BOOK! When I have been in chats with networking guys, and we have been discussing various features, I can point them to sections of the book, and if I need to confirm something I can double check it quickly. You do not need to be a networking guru to use this book. I have/had a CCNA (it has expired), so I have a fair idea, but I am by no means a networking guru and I have learnt plenty from […]

Dell Compellent and SCSI UNMAP

May 15, 2016 Bilal Ahmed 0

Dead space reclamation (SCSI UNMAP) Basically the UNMAP command is used when you have Thin Provisioned LUNs, you run it against VMFS 5 datastores, hopefully freeing up some space. This will allow the hosts to correctly report the list of deleted blocks on the datastore to the array. It basically is a space reclamation feature that helps reclaim space left by deleted data. The main reasons you would want to run this on all Thin Provisioned LUNs, would be because of: Storage vMotion, VM snapshots and VM deletion. As even though the VM/Snapshot etc has been deleted it doesn’t mean the array is aware of this! It was disabled in ESXi 5.0, due to various issues and enabled in 5.1 by using […]
