how much RAM is required for 80 gb source data and 100 users.
Just to give a rough picture - 80 GB data becomes 8 GB (assuming 90% compression). When you open the application, it would be
8 GB * 4 (size 4 times in RAM compared HD) = 32 GB
User session memory = 5% of 32 GB = 1.6 GB * 100 Users (160 GB).
So, you may need roughly 192 GB of RAM.
That's impossible to tell. You can process 80GB of source data and end up with 5Kb of data or you can end up with 200TB of data. It all depends what you do with your source data.
