Plan a Large-Scale User-ID Deployment
When deciding whether to use Windows Log Forwarding
and Global Catalog servers for your User-ID implementation, consult
your system administrator to determine:
Bandwidth required for domain
controllers to forward login events to member servers. The bandwidth
is a multiple of the login rate (number of logins per minute) of
the domain controllers and the byte size of each login event.
Domain
controllers won’t forward their entire security logs, they forward
only the events that the user mapping process requires per login:
four events for Windows Server 2012 and MS Exchange.
Whether the following network elements support the required
bandwidth:
Domain controllers—Must support
the processing load associated with forwarding the events.
Member Servers—Must support the processing load associated
with receiving the events.
Connections—The geographic distribution (local or
remote) of the domain controllers, member servers, and Global Catalog
servers is a factor. Generally, a remote distribution supports less
bandwidth.
