    Minimum RAM needed for Server v10.5+

    shrikant.patil.2

      Hello All,

      we have Single node installation running Server v10.4. Our team is planning to upgrade to v10.5. I already checked the minimum Hardware requirement on Tableau page but wanted to get real world implementation experiences from the community before proceeding with upgrade. I am anxious that current RAM won't be enough for PROD environment.

       

      Tableau Recommendation:

       

      Install Type

      Processor

      CPU

      RAM

      Free Disk Space

      Single node

      64-bit

      8-core, 2.0 GHz or higher

      32 GB

      50 GB

       

       

       

      Our Environment:

       

      Install Type

      Processor

      CPU

      RAM

      Free Disk Space

      Single node

      64-bit

      8-core, 2.5 GHz

      64 GB

      150 GB

          Well, you're starting in a good position as your RAM is double the prod recommended.  So that's really good.  My org hasn't upgraded yet to 10.5 so I can't give full evidence that RAM isn't affected, but during beta testing I didn't notice any major effect on RAM.  And if you do, you could always shorten the vizql session durations from the detault of 30 minutes to something shorter as the vizql process is one of the major consumers of memory.

            A rule-of-thumb is 8GB RAM per core.  8 cores x 8GB RAM = 64GB RAM so you look good.

             

            The Hyper data engine in 10.5 takes advantage of RAM so really the more you can use the larger the extract size can be and, basically, processing time will be faster versus a hard drive.  If it doesn't have enough RAM it will then use spooling (the hard drive) and that, of course, is slower than RAM so performance will drop but it shouldn't be anything more dramatic than the same situation with the "old" Tableau Data Engine.
