Opvizor Update – Kill those snapshots !!


Opvizor is a product that is aimed at proactively addressing any critical errors in your vSphere environment and fixing them. Its unique turnkey solution is built on the premise that it proactively health checks and provides solutions to your vSphere Admin so they can concentrate on other work.

Today sees the release of a new free beta tool called ‘Snapwatcher‘.

You can finally say goodbye to those sneaky broken and invalid snapshots hiding in your VMware environment !!!!

Snapshots are almost a prerequisite in virtualisation, as they give virtual machine administrators the ability to return to previous stages if problems occur inside virtual environments. Unfortunately these same snapshots can quickly hog your disk space if you don’t regularly monitor and manage your virtual environment. Many invalid snapshots occur automatically when backup solutions trigger snapshot creation and deletion; whenever VMware struggles to delete a snapshot, an invalid snapshot is born. Broken snapshots can grow like wildfire if you’re not keeping track of them, and quickly balloon to consume most of your free disk space.




The team at Opvizor noticed hundreds of terabytes of wasted broken or invalid snapshots in their customer environments and had a real passion to attack this head on. The problem with these snapshots are that a single Snapshot’s Delta-file is able to grow to the same size of the original file. Broken snapshots are a common problem and affect 81% of all VMware vSphere environments. If left undetected, they can easily amass and cause space shortages in datastores.

Snapwatcher is designed to be simple to use. With a single click, anyone can find and fix old, broken or invalid snapshots. Through system wide monitoring of the VMware vCenter systems, Snapwatcher monitors all VMware snapshots and sends progress reports to notify you of how much space it was able to free by repairing or removing the snapshots.




You can download and try Snapwatcher here on the opvizor website by clicking “Try Snapwatcher by opvizor.”

Simplivity and the proliferation of Hyperconvergence – VFD4

In a first of series of blog posts covering some of the vendors that caught my eye at VFD4, I’d like to introduce you all to Simplivity.


Hyperconvergence, Convergence, Modular, Traditional – Lots of buzz words used in I.T. covering a multitude of offerings but for the purpose of this post I’d like to define hyperconvergence. Simply put, this involves collapsing several I.T. building blocks such as Compute, Storage, Networking & Apps into a single building block that can be deployed to a datacenter with minimal fuss. Simplivity have taken this a step further by intelligently adding capabilities such as Backup with Dedupe, D.R., WAN acceleration and Cloud Gateway. The diagram below (taken from Simplivity) highlights the journey from the traditional stack to a Hyperconveged stack. This truly simplifies the method of deploying virtualisation stacks to a datacenter and encompasses several technologies aiming to make this a lean and cost effective approach to companies wanting to go down the road of virtualisation. Simplivity uses its patented Omnistack technology on commodity x86 hardware to give you its building block known as the Omnicube.


The company is led by its charismatic CEO – Doron Kempel. This is a man I admire for his tenacity and ambition and moving from a very different life outside I.T. to his MBA and onwards to work for some large I.T companies has helped him to develop his vision and understanding for where Simplivity can deliver value in a simplistic fashion. » Read more

VFD4 – What I learned and who I saw

All views expressed in this post are mine and do not represent the company I work for. This event was fully paid for by Gestalt IT and I received no compensation in benefits or money to attend this event.


I’ve been back in the UK for a few days and before I offer my thoughts on some of the vendors that caught my eye, I would like to offer some words of wisdom on the interesting people I met.

The key to any event is PLANNING, PLANNING and more PLANNING. Gestalt IT has run several events over the last few years so I’m sure this is becoming second nature but you can never be sure when there are so many cogs spinning in an intricate timepiece.

Think of Steve Foskett as the master conductor. He directs the orchestra comprised of Tom Hollingsworth and Claire Chaplais to create the most stunning music piece that you could ever imagine. This combined with the percussionists (the vendors) resulted in a display that ensured all the components of the band came together well to hypnotise the audience (the delegates). Organising logistics of the day, the evening activities and ensuring the media crew are on point was fascinating to watch as I am also a planner at heart and enjoy managing several elements in I.T. so it was refreshing to see this from another perspective. Credit to the Gestalt IT team in putting these wonderful events together as they really bring together a great bunch of delegates from around the world to converse and interact with senior representatives from the companies that were represented.

Moving on with this theme, the audience was a group of really knowledgable, diverse and interested minds (not to mention varying accents) and this culminated in an environment that was both collaborative and creative at times in terms of questioning the vendors on their technologies. He’s my breakdown on my illustrious companions :

Larry Smith Jr was a very quiet guy in front of the camera but clearly liked a varying amount of technology both in the networking, virtualisation and the DevOps side. A well liked individual who contributed well.

Amy Manley was the only lady on the delegate panel and she has both the brains and the beauty of a true virtualisation chick lady. Well thought out questions were posed from her and she had a broad range of experience also. It was also refreshing to hear someone else that had used the Dell Foglight product before as well as her political challenges at work similar to some of mine.

Christopher Kusek (make sure you do not call him Chris) was brilliant in his questions and I particularly liked his questioning process. He had the most diverse set of skills and this has been built up with years of experience both working for vendors and for other companies. I was glad to learn from him also.

James Green, the tallest youngest member of the delegates (made me feel like a dwarf), had attended a previous TFD event and is also very good in the virtualisation (VMware) space and also the blog post master delivering live blog posts after each day. What a machine !!

Emad Younis was a quiet succinct delegate who really thought about the vendors that were presenting before presenting killer questions. A great fellow and very admired amongst the group.

Mike Preston was the only Canadian in the group and got a lot of stick for it. He co runs the Toronto VMUG and has been in virtualisation for a loooong time. A great chap to have in the team and was happy to enjoy the better weather in Austin compared to Ontario.

Julian Wood was my fellow UK blogger (a South African at heart) who was methodical and precise with his questioning of the vendors. It was his first VFD like mine and clearly enjoyed every minute. I’m sure our paths will be crossing again soon.

Matt Simmons was another quiet member of the team who had some great Linux and Virtualisation skills enabling him to dig deep with the presenters where he saw weak areas. A great all rounder.

Jeff Wilson was the only Microsoft centric guy but this was good as its always nice to see how Hyper V is represented amongst the vendors. It was good to talk to Jeff about Systems Center and know how he has used Azure and this spearheaded some of the conversations with the vendors.

Marco Broeken came in from the Netherlands and is someone I have followed for quite some time due to the VMworld events he has attended and the after hours events he has organised. Another previous TFD delegate that has a wide scope of knowledge and very amenable with the crowd.

Lastly, Justin Warren, who has his own company and is a passionate journalist from Melbourne, was one of the guys who I learned a lot from. His calm demeanour and outward appearance may lure you in but you never know what he is going to ask next. His inquisitive mind was what I liked the most and I’m sure I’ll be using some of his tips and tricks in my own posts and future direction.

So that’s a long list of delegates and organisers and I can say the experience is something I will never forget and would relish an opportunity like this in the future. As I cover some of the vendors in my next post I’ll be sure to include the names of the individuals that caught my eye as well as the technology that underpinned much of the vendors core go to market strategies. Stay tuned folks….

Virtualisation Field Day 4 Preview – Austin, TX

We’re almost there now and I’m looking forward to the kick off – Refer to my earlier post. Most of my fellow delegates have already posted some extensive research into the companies presenting and so I’ll refer you to their pages for more information – Justin Wood, Mike Preston and Justin Warren. There are some excellent insights into the companies that will be on show so please have a read.

I’d like to do something a little different from my fellow delegates as they have already done a great job in giving you a technology overview and personal thoughts. Firstly, I’d like to impress on you the effort it takes to organise such an effort. Credit to Steve Foskett and his team in bringing together the logistics to make this a successful effort. They have regularly been sending out tips and knowledge to make sure the delegates and the companies attending make the most of their time. I’m sure that running an event like this always has its pitfalls but I’m guessing the experience of doing these on consecutive occasions has helped to mould the process and sequence of events that help the Gestalt Team to be more efficient and conscious of good time keeping and communication. So far I’ve experienced this already and am sure it will be much the same for the remaining week.

Secondly, I’d like to draw your attention to the companies that are presenting below (in no particular order) :





Scale Computing




















Many of these are household names (if you work in the Virtualisation Field) and some of these are unknown unless you use their product set already. Each vendor has 2 hours or less to present their product vision, innovation and any game changers they see in their roadmap. Let’s not forget that to stand up and rotate amongst speakers in front of a full audience wanting to dig deeper and critique a product is no mean feat. I think that they have a tough job as they are live on camera and have an audience that is watching every second unedited and live. A big credit goes to them for attending these types of event where they are on show and their intellect is on show for the public to see and publicize via the various social collaboration tools at their disposal. I have been very impressed by all these companies already from the angle of strategic management and leadership.

As a manager and a leader, I always look for the foundation or the roots of the tree from which stems the organisation. Names such as Doron Kempel, Michael Dell, Shmuel Kliger and Jeff Ready may not mean much to you but these are just some of the names that I look into so I can understand their backgrounds (both business and technical) and appreciate why they have contributed to some of the names above. Drive and ambition is synonymous with some of these thought and technical leaders and when you exude such a culture in a company then generally your products, product development and marketing start to gel by creating a culture of trust and success. Although, I won’t be meeting most of the managers on the core leadership teams at these companies, I’d like you to remember that sowing the right seeds sometimes yields the fruit that you desire whether it be a technology company or a small team at a company or indeed your personal life at home.

I’d like to leave you with this great quote from a certain web crawling movie – “with great power comes great responsibility”. Its a bit tongue in cheek but I take this from an angle that these thought leaders know they can shape a company and in knowing this they have helped to also inject this culture in their employees to grow their business. Technology drives a large part of this success model but its with the enthusiasm and desire that a company goes from strength to strength and gives them a distinct edge of their competitors.

Stay tuned to my blog and please watch the live stream if you are able to. This promises to be a great event…..


2014 Review – The Year that worked for me…


2014 is just about over and I wanted to take a few moments to review all that I have achieved and areas for improvement (as always). I have not had my blog set up for long and to be part of Eric Sieberts top blogger list was a great honour even though it was in a very low position. This gave me a firm impetus to be stronger in the community and spread my thoughts and knowledge to gain a more active following. I was also lucky enough to attend VMworld in Barcelona and numerous local VMUG’s as well as being recognised by VMware with a blogger pass although the company I work for agreed to fund the trip. I also attended a key Gartner conference where I learned a lot from some of the future writers and researchers and this has made me broaden my horizons. I’ve written a lot of articles over the last year and gained a tremendous amount of support from other technologists with a passion for writing about new innovations and I feel that I have really come on strong in sharing this with you all. This has been shown in the comments from those of you I met during events and also in my ever increasing Twitter following.

My posts have been varied in content and I’ve tried to balance both technical deep dives with my thoughts on the dynamic world of virtualisation. As we all know things change at such a fast pace that its important to keep in touch with what is happening both in the Enterprise and in the startup market.

Networking must not be thought of as something to be scared of. Initially I was always hesitant in talking to like minded individuals but I have found that talking to peers and other technology enthusiasts has really opened my eyes and indeed led to my development as a technologist. Its fundamental to all things we do to become successful as a blogger or writer so please remember this. I will be doing this a lot more in 2015 and continue to make myself known to the wider community.

I was also grateful to be awarded to the prestigious vExpert title from VMware which shows that I was heading in the right direction when it comes to my external speaking engagements and blog management.

Although leadership, management and technology strategy forms a large part of my current position, I have still been able to stay in touch with my technical side by learning more about Cloud, SDN and EUC and also sitting exams where I have wanted to keep my technical knowledge current and be able to contribute to discussions both in and out of the workplace. I wanted to take my VCAP-DCA exam this year but alas life, both personally and in business, was very hectic and so I could not but I was glad to recertify my VCP and also complete my VCAs.

Above all, I will be setting myself some goals to further my career and ensure that I continue to push my own limits and learn new areas of virtualisation. I am very happy with the way 2014 turned out and have more exciting opportunities in 2015 to stretch myself further. I hope you, as readers, have enjoyed my posts over the last year and will keep coming back for more as I continue to stretch the boundaries of technology in 2015. Thank you for your support.

VCP550D – Its over now

I realised that my current VCP was due to expire in March and was even more shocked when I realised the deadline for the Delta exam was 30th November 2014.

Since I don’t get to touch a lot of VMware products these days in my day to day life I wanted to make sure I used my homelab to look at some of the new areas such as VSAN, VDP, vFlash Read Cache and Operations Manager in some detail. I used this great webpage ( Link ) by Anthony Poh to read some PDFs and also ensure I was comfortable around the Blueprint areas. Thankfully I just about PASSED !!!


PHEW…..now I can concentrate on my day job again….
