I wanna know how to calculate how much ram there is needed for our setup?
Lets take an example:
No. Concurrent users 200
How do you calculate approx how much ram the server needs?
Go to Solution.
Aproximately 900 GB
RAM = (RAMuser × No. users) + RAMinitial
RAM〗initial = QVWsizedisk × FileSizeMultiplier; this is the initial RAM footprint for any application
RAM〗user =〖RAMinitial × userRAMratio; this is the RAM each incremental user consumes
QVWsizedisk = SourceData × (1 - CompressionRatio); this is the size, on disk, of a
userRAMratio: range between 1%–10%
FileSizeMultiplier: range between 2–10
CompressionRatio: range between 20%–90%

awesome - thank you!
Thanks Tresesco for the explanations and the file
As Thomas said: awesome
tresecso - Does that means i need 4 enterprise servers? And 4 licenses? That will be around 200.000 (Enterprise server license i DKK) * 4
Certainly not !
I guess you are talking about CPU core. Options there are in 'OR' mode. If you have dual core or quad core ...
I dont get it?
My demand says
So if my Demand is 8000 CPU seconds
And one 8-QuadCore delivers 1920 CPU seconds
Dont i need 4*1920 then?
Right. But it is related to cores; not the licenses. You have to increase the hardware capacity (32-core CPU + server). That is what it tells about.
