|
| I have a single forest/single domain setup with about 80 or so
geographically
| dispersed sites. I have my ISP's WAN topology so I know which sites are
| located on the same backbone, etc. All of my sites are connected by at
| minimum a T1. Currently, our AD site topology is such that there are
about
| 10 AD Sites, which are loosely based on the geographical region that they
are
| located in. Obviously we have difficulty when users at one physical
location
| authenticate to another physical location (especially when we make a
change
| to one of our monolithic GPOs, which is another problem being solved by
| another engineer).
|
| My task is to redesign our AD Site topology to minimize replication
latency
| and authentication issues. I've got the sites listed by their location
in
| the ISP's WAN topology. What I have planned to do is to make each
physical
| locaiton a single AD site. The only thing I'm not entirely sure of is
how to
| design my Site Links. I had planned to identify a single fast but
| not-heavily-utilized server in each geographical location and add it to a
| single "Core" site link. I would then like each of the sites in each
| geographical region to replicate with its closest core server. My
question
| then, I suppose, is should I create individual site links for each of the
75
| other sites to connect back to their closest core server, or can I create
a
| single site link for each of the 5 or 6 geographical regions and just
include
| one of the core servers in that site link?
|
| I'll try to give a quick example. Let's say I have 4 geographical
regions:
| N, S, E, and W. And each region has a site numbered 1-5. So I will have
| servers N1-N5, S1-S5, etc. If the servers numbered 1 are my "core"
servers,
| I would have a single "Core" site linke with N1, S1, E1, and W1 in it.
Would
| I then want to create separate site links for N2-N1, N3-N1, etc. Or can
I
| create a single "North" site link that includes N1-N5?
|
| Are there problems with having a bunch of servers in a single site link?
Or
| multiple site links that have common servers? I seem to remember
somewhere
| reading to only have 2 servers per site link, but that seems to me to
defeat
| the purpose of being able to put multiple servers per site link, which is
to
| avoid having to do the manual work of setting up 10 redundant site links.
|
| Thanks for any help.
