Hi,
Despite the fact that i agree in general with your comments, in
reality
it all comes to money..
So in this case, if i could prove that ZFS was able to find X amount
of
duplicated data, and since that X amount of data has a price of Y per
GB, IT could be seen as business enabler instead of a cost centre.
But indeed, you're right , in my case a possible technical solution is
trying to answer for a managerial solution..however, isn't it way IT
was
invented, that i believe that's why i got my paycheck each month :)
OK, I think I've pulled your leg just a bit :-) Here is the problem,
if you
charge per-byte, then when you dedup the cost per-byte increases.
Why? Because you have both fixed and variable costs and dedup
will reduce your variable (per-byte) cost.
cost = fixed cost($) + [per byte cost ($/byte) * bytes]
The best way to solve this is through managerial accounting (aka
change the rules :-) which happens quite often in business. See also

Finally, as my managerial accounting professor says, "don't lose
money" :-)
