Hello all,
We are migrating off of Banyan to Windows 2000 in late July and
through August. Concurrent with the migration will be an
infrastructure overhaul. I would like to lay out my plans and
thoughts; any comments, advice, criticism, improvements, etc. greatly
appreciated.
I have 95% of my hardware:
Dell Poweredge servers:
1550 (6) - file servers
6450 (2) - SQL and Exchange servers
2450 (1) - SQL
Cisco Switches:
2948G (1) - distribution switch
2900xl (8) - access switches
various numbers of 1900/2800 to be phased out
Cisco Aironet Wireless:
2 parabolic, various yaggi and omni antennae
a number of workgroup and access bridges, various sizes.
The new environment will consist entirely of new servers, no upgrades
from old environment.
I've taken my first crack at using Visio 2000 to try and lay out a
high level conceptualization of my planned design. If interested,
please download the diagram: http://www.tuzzy.org/design.zip 200k
Currently our network is on one segment and I am creating vlan's. This
is an ambitious project for my experience but I'm confident, although
I realize it'll take a lot of work and study as I go. I've been
researching this scenario for some time now, and have attended a BCMSN
week long course with Global Knowledge. So, I may be in dim light but
not totally in the dark ;-)
Physical Sites consist of:
Main site; includes main administrative building and 6 outlying
quonset (huts). Fiber from main building to one hut, fiber between
huts. Currently in place and operable. Main server room; distribution
switch, access switches in main building and physical locations.
Heritage site: approx. 4 miles from main. Will connect to Main Site
via Aironet, parabolic at Heritage and at Main.
Northstar site: approx. 400 yds. from Heritage, connected via fibre,
currently in place and operable.
Daycare site: approx. 800 yds. from Heritage, will connect via
Aironet.
Home: approx. 1 mi. from Heritage, will connect via Aironet.
All operations must take place within 10.200.x.x range. Our
organization is one of three trees within the 2000 forest. Each tree
is an independent organization with close ties. One domain per tree.
My plans:
All servers are Windows 2000, all desktops 2000 Professional.
Each VLAN consists of 6 ports on the 2948 switch, each port (as
needed) will go to a 2900xl switch for eventual end user access,
possible direct 2948 to desktop in some cases.
VLAN 1
10.200.1.x / 24
Serving enterprise;
Exchange 2000 / Universal file server box
ISA (firewall) box
Primary DNS, DC, DHCP, Global Catalog
VLAN 2
10.200.2.x / 24
File server for info systems, main building.
Secondary DNS, DC
DHCP?
3 users
VLAN 3
10.200.3.x / 24
File server for huts.
SQL backend server for online application, access from huts.
DHCP?
50 users, web server.
VLAN 4
10.200.4.x / 24
One box, 6450, SQL server and file server for finance and services,
main building.
DHCP?
6 - 12 users, critical data, high resource demand
VLAN 5
10.200.5.x / 24
File server for administrative staff, main building.
DHCP?
75 users
VLAN 6
10.200.6.0 / 24
Spans from main building to heritage center, approx. 4 miles distant.
Parabolic and bridge, Aironet, at main building and Heritage center.
Bridge on each end connected to a 2900xl switch.
File server for Heritage center, possibly daycare.
Daycare connected via workstations -> 2900xl -> aironet -> heritage
Northstar has own servers, connected to Heritage via fiber.
Home will connect to Heritage via wireless (low priority).
Possible (probable) second server at Heritage, possible server at
Daycare.
DNS (cache only), DC, Global Catalog
DHCP?
50 users
VLAN 7
Not utilized.
VLAN 8
Gateway to existing Banyan network.
So there we have it.
This is actually my first time writing it out in detail and that in
itself has been beneficial.
If anyone is feeling ambitious and generous I would more than welcome
a picking apart of my logic, diagramming, any input at all welcome.
I'm sure I have some gaping omissions, leaps of logic or
considerations not yet considered. Chances are I'm going overboard
with the segmenting? I realize the extra admin chores but think the
trade off is tolerable.
If you've read this through, I already owe you my thanks ;-)
