    Capacity planning for clearspace x unlimited...

       

      Need some advice on how to plan for unlimited clearspace x. Want to know where we may hit the roadblock and when may really need a cluster node. THe information on the jive site looks like they suggest to buy the cluster node for the below in terms of pages only.

      CPUs

      RAM

      Location of App Server and Database

      Clustered?

      500,000

      20,000

      2 dual core CPUs (at least 2 GHz)

      Yes

       

       

      Our hardware

       

       

      Two  Dell 2950 with two Xeon®X5460, 2x6MB Cache, 3.16GHz, 16 Gb DDR2 667 RAM, 15k rpm drives - one for the app server and the other for DB.

       

       

      I m looking for feedback from people who are currently running with at least 5,000 users and want to know their experiences and problems they faced with single server. I would also like to know about the below queries.

       

       

      1. Does total number of offline users have an effect on the performance? Do we really need to plan for performance for offline people?

       

       

      2. Can having too many communities affect the system? ~200 communities..

       

       

      3. Is clearspace read heavy or write heavy assuming people discuss, blog and write docs?

       

       

      Thanks

          1. Does total number of offline users have an effect on the performance? Do we really need to plan for performance for offline people?

          No, offline users shouldn't affect performance.

           

          2. Can having too many communities affect the system? ~200 communities..

          You'll definitely want to up the cache size (you can do this via the admin console) for the community cache and there are a couple places in the application where having a large number of communities causes an awkward UI, we're working on that for 2.0.

           

          3. Is clearspace read heavy or write heavy assuming people discuss, blog and write docs?

          Totally depends on your community. Internal or external?  In general, I'd guess that an internal community would have more writes, you get more lurkers on an external community.
