Re: I hate...
Some years ago we tendered for storage and received a wide range of quotes, and one factor that swung us in favour of the (then) Sun storage system was the fact you had a fixed selling price with all features included which was very unlike, for example NetApp. This mattered a lot because:
(a) we don't want to have issues in future with compliance to the terms
(b) we were not sure of what we might use. Sure we needed NFS, but CIFS? In our case maybe useful, maybe not. If we had to pay more, the answer would have been a definite 'no'.
So really when it comes to selling we want a simple up-front cost and not strange complex variations depending on just what we do with the system.
Really, for storage it should be as simple as possible, such as how much usable capacity, and then what level of support you need. Anything else and they are simply looking for ways to gouge you.
p.s. Of course Oracle changed that, but we are trying to get out of their grasp as soon as practical.
