How much usable capacity will be available for a specific configuration?
Sun has written a capacity calculator. It is a python application that provides the RAID and usable capacity options for a given hardware configuration. In needs to communicate with a 7000 system to calculate the result. While this is not ideal, it work with the simulator so you do not need to have an actual appliance. Adam Leventhal wrote the original version of the calculator, but it has since been updated by Ryan Matthews. It is available here. In response to a few requests, we have created an online capacity calculator.
