DW are memory hungry...
It really depends on the application needs, there will
be less than 20 users, if the design is good they
won't be hitting raw ultra-detailed data with query
using only one dimension ...
Depending on the kind of data loads, 4G of ram can be
quite enough for a small DW.
Before buying the hardware, is there any capacity
planning that will be done ?
