Why we did VMware Site Recovery Manager
As we grew, the requirement for our core Computing resources to have a segregated site agnostic DR (Disaster Recovery) site had become more apparent.
To mitigate risk in the event of a total site failure/Fibre cut to our Production Site, Natural Disaster etc. the requirement to have the Production Server Room replicated and the ability to bring up the replicated site quickly and efficiently was mandatory to ensure the continuation of Business/Financial and Clinical care services.
We architected a solution to ensure the easiest, most scalable and robust way to provide a replicated site, for the day which we all hope never happens. Based on past technical design decisions, A replicated site was always deemed to be the best way to ensure our business compliance with the inability for the Production Site to function. The previous solution was to have Synchronous block level replication over dark fibre between Hitachi SANS to provide the storage layer component, and to provide stretched cluster technology.
However there were some issues with this.
- The cost of dark fibre was prohibitive,
- The age of the server hardware was in excess of five years
After quite a bit of study and gnashing of teeth, I received my VMware VCP5 Certification Today.
I must say it’s quite satisfying, on completion of the exam, I spent some time going through various forums across the internet to see how other professionals found the exam. It turns out I was not alone, it’s quite a difficult one, many questions focused on VMware Storage Appliance and VMware Data Recovery, (both of which I would not in good conscience use in any enterprise situation).
I fail to see the relevance of the amount of questions regarding these topics, considering the type of content was not covered in any real detail in the course, and if you are actually using VMware in an Enterprise environment you would not be touching them anyway. I suppose in order to pass the exam all facets of the technology should be explored.
This I suppose relates to another post I made in regard to the quantity of hours required to keep your skills sharp and your knowledge of products and potential solutions in perspective.
I would average per week at least 20 hours of my time doing personal R&D, whether

As incredulous as this sounds, she makes some very interesting arguments.

Why ICT professionals need to understand the OSI model.
I have simply lost count of the amount of IT professional’s I have encountered that simply have no idea of what this is.
This, everyone is what sets you apart from the rest, this….. is your never wavering friend that helps you through almost every technical issue you encounter…..this….will simply set you free. Silly cliché’s aside, this OSI model helps me every day, every single day.
To have a fundamental understanding of the frameworks involved in all that button poke-jiggery that you do everyday in your ZEN style IT guru-ness is crucial when random button pressing fails and nobody has really bothered documenting their trials and tribulations on Google in a step by step guide that doesn’t really require you to understand whats actually going on.
It is what you refer to when all else fails, well to be blunt it’s what you should refer to straight away. A very simple example, “My internet does not work” – “is the cable plugged in?” = Layer 1 and so on. Here is a shameless rip off a website that explains what it is.
The Fall of Pride within IT
There was a saying my father always said to me as a child when I was helping him in his workshop. He used to say, “Make sure your job fits the customer or the need, there is no point doing too good of a job.” “What was too good of a job? I thought, and why wouldn’t you make sure that the job you did was the best you could do?” As I am now older it’s all too apparent what he meant, don’t waste your time and expertise if it goes against commercial reality.
This however is still a bitter pill to swallow. If I got up in the morning and thought to myself that I will go to work and do a mediocre job, to be honest I think I would stay in bed. That as an IT Professional is what motivates and drives me everyday, to do the best I can everyday, its my validation as a professional, as though I’m in a constant state of learning. I simply couldn’t imagine being in a place where I wasn’t trying to make “that” difference. Having said all that, a startling amount of IT professionals that I encounter somehow do not share my mindset. It’s a cause of most frustration and confusion for me, IT is a job of passion, it has to be.
We do long hours, we have to be constantly learning new technologies, we have to do immense amounts of study, we typically deal with people who have less than ideal planning strategies, we are quite commonly put in situations that the only reason we are there is because something has gone very wrong. In order to push
