Hi,

We are implementing a 'middlewear' layer to an underneath storag= e and
need to estimate costs for various system configurations.
Speci= fically, I want to estimate the resources (memory, disk) for our
data mo= del.

Is there a tool that=A0 given certain storage configuration parameters,<= br>column family fields number and sizes and other details, and then
wor= kload-dependant =A0parameters such as read/write average rates etc. can pre= dict the
resource consumption (i.e, memory, disk)=A0 in an offline mode?

Thanks,
Miriam
