Nothing is more important than the reliability of data

Surendra Verma of Microsoft introduced ReFS here.

He talks a great deal, then makes the most important point and it almost gets overlooked:

"...with the caveat that nothing is more important than the reliability of data. So, unlike any other aspect of a system, this is one where a conservative approach to initial deployment and testing is mandatory." (my emphasis)

This is the thing that almost always gets overlooked. I've worked in organisations where they have no clue what they, an IT department, should be providing to the larger organisation. Management overhead gets bigger each year, office politics get worse as the organisation gets bigger and less effective, millions get spent on hardware or software. And guess what? They miss their purpose.

Their objective is to ensure data remains available to the wider organisation. Everything else is just plumbing.
