Topology question

Hello all,
I am an administrator at Data center, actually we have
like 3000 sites getting their internet connection from
this data center.
now we are thinking to upgrade the servers to Win2003, so
what is the steps you guys recommend, i mean how many AD
you suggested to assign,also how many ISA you recommend
to put? back-end and front-end??

Tina,

Well that answer would depend on a few things:

1) How much $ do you want to spend on a consultant to
assist you in the design?

2) Are your sites (3000 is a LOT) logically seperated?
(i.e. region, function, business unit, etc)

3) What operating system your on now, and how it's
designed.

4) What kind of access you want for your sites (filtering
all internet traffic back through a central site for 3000
sites would probably NOT be a good idea. There are ways
to manage that traffic by region, or locally using
a "corporate" policy that is centrally managed).

5) And a few other questions!

I could probably put together a nice topology
recommendation with the major implementation steps, and
ancillary product recommendations, but for this kind of
project I am afraid I would not be able to do that for
free.

Hope this helps ( I probably gave you more information
than I should have considering I typically charge for
what I just asked! :-) ) and feel free to let me know if
you would like to speak about a formal topology
recommendation project.

Regards,

Tim

I don't really mean to sound rude, but wouldn't a data center
administrator have better questions to ask? Or at least provide
better details for the ones they do ask?

For example, "How many AD you suggest to assign?" How many do you
have now? How many do you think you need and why? Do you understand
the implications of AD? Do you realize that Active Directory isn't
quantifiable as in "Oh, for those 3,000 sites you need 19 Active
Directories..."? Do you understand that we really don't even know
what you're asking with that, since it could mean zones, separate
trees, forests, etc.?

Same for how many ISA. 3,000 sites that have no more than three
connections to each in a month needs a much different setup of ISA
systems than 3,000 sites each doing a half million connections a day.

Capacity planning for every data center I've been involved with has
been an ongoing process, not a quick question in a newsgroup.
