    Where did you see the 80k max limit for CS14? I am reading the RC documentation now and will post more on CS14 fairly soon.

  2. markga says:


    Each CS14 server, based on hardware above, will accomodate up to 10,000 users per Front End. This is just a rough baseline for beta. There will be better sizing tools to provide better sizing guidelines for 1500-2000 users.

    What sort of numbers is this for? I seriously don't think my 1500-2000 users would need infrrastructure like this.

    Hi Matt,

    I seen elsewhere that max users per pool is 80k and above you have 100k per pool with 10 servers?

    Will CS14 scale to 200k users in a single pool for IM only like in OCS 2007 R2?
