| | 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.
