I am a storage capacity planner and my company needs to reserve storage on storage arrays 3-12 months in advance. There is basically nothing out there to do what I need it to do... in fact it is practically like a hotel reservation system.... we buy a EMC VMAX for $2.5 M and it has 1PB of storage.... each storage array holds 50-150 clusters.... and as we plan our provisioning out... we can calculate the cost based on the footprint, etc....
So each Storage array is a "facility" or "hotel"
Each storage group is a "room"
Each location is a datacenter/location
There is a lot of parallel concepts between professional storage capacity planning and a hotel reservation system.
If you want to consider going down this road, I can provide input and perhaps you can find a market for this new implementation. Thanks, Jonathan
