Those old enough will remember the AS/400 (now called iSeries) computers map all storage to a single address space. You had no disk - you had just an address space that encompassed everything and an OS that dealt with that.

Just in case anyone else is wondering:

I must admit that until looking into it more closely i figured it was no different from the memory map of a micro. Silly me.

What were the pros and cons of that design?

I never programmed for one myself, but I imagine that it's a very alien world if you see everything as a single vast address space of persistent objects. I imagine layers of software would make it less strange in order to facilitate porting programs to the platform - I remember IBM ported Node.js to it, so, there must be a way to see it as a more traditional machine.
