DSfW depends on many core services that are mutually dependent. Ensure that these services get enough resources such as Memory and CPU. Non-availability of resources for any of the DSfW services might lead to domain malfunction and slowness at the client workstation.
For an enterprise with user base up to 2000 users per domain and associated resources such as user workstations and shares, you must have at least two domain controllers. Each Domain controller must have at least 8 GB RAM and a Quad-Core CPU. For an enterprise with more than 2000 and less than 5000 concurrent logged in users per domain, you must have at least 4 Domain Controllers. Each Domain Controllers must have at least 16 GB RAM and a Quad-Core CPU.
NOTE:If the enterprise size is different from the ones mentioned in this section, we recommend that you contact Novell Services Qualified Partners or consultants.
