Question { Microsoft, 12188 }

I don’t understand clearly about global catalog server. I
think we have global catalog server can help improve the
respond time user query.
But do we need only one or more global catalog server is
better. What different effects?

Answer

Exchange server use global Catalog to lookup AD objects.
Becsae GC contain full index of AD objects.

Requirement of GC is depend on the mailbox load and need to
follow the exact ratio recomended by microsoft.
In exchange 2010. 4 MB Server : 1 GC ratio
8 MS server : 2 GC (only one GC require
if you have 64bit GC server).
