Server 2012 DirectAccess Capacity Planning RRS feed

  • Question

  • Hi

    I am looking to deploy a multi-site DA 2012 deployment.  Each site will have a 2 node array using NLB.  I am looking for a capacity planning guide for 2012 URA to make sure I have it over spec'd for failover to one site.  There is approx 1200 users in total, so worst case scenario if 1000 users need to access the array I need to have capacity.

    I so far have gone with 2x4 processors and 8GB RAM per server.  This is hosted as a ESX guest.  I understand IPHTTPS is now lighter if connecting with a win 8 client and Teredo makes better use of processors.

    Any thoughts apreciated

  • AFAIK no public guide is available.

    It all depends on how much traffic a typical client generates. One thing that comes into play is that NLB doesn't really work well with bandwidth usage exceeding 500 Mb/s. Maybe your internet connection "handles" this for you (available bandwidth being less than 500 Mb/s).

    I would go with the above spec to start with and do performance monitoring, personally I would consider more RAM but as you are using load balancing you can always throw in another node.

    As there aren't any guidelines yet and I don't know anything about your clients traffic profile, perfromance monitor is your friend. You also need to be prepared to add extra resources to your servers.
