    Hardware Specification Understanding

    shan dar

      Hi Forums/Friends,

       

      At Presnt I have followings:-

      SourceData = 50GB

      Concurrent Users = 200

       

      I want give the Hardware specification for QlikView Enviroment Installation.

      On google and surfing I had got the following information.

       

      RAM = (RAMuser × No. users) + RAMinitial

      Where

      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

      QlikView file

      Assumptions:

      userRAMratio: range between 1%–10%

      FileSizeMultiplier: range between 2–10

      CompressionRatio: range between 20%–90%

       

      I am not able to understand the complete calculation clearly.

       

      In furture the SourceData will be more the 50GB & Concurrent Users will be more then 200.

      So, How to caculate the Hardware specification for next 5 Yr assuming every year the database will get increase by 10-15% and

      User also 10-15%.

       

      If any body can explain the above calculation step by step clearly then it will be great help for given

      apporximate Hardware configration requirement.

       

      Advance Thanks
