| I am still a newbie to these things and am desperate need of some assistance.
All help is greatly appreciated and thanks to all for having the time to set
this up and to support so all can get help when they need.
Ok the situation is like this :
I have a MAN which consists of 6 LANs of which these have sub-LANs.
I have fiber to the desk throughout the network.
In one of the 6 LANs is my central server room (call it LOCATION 1) wherein
resides the following : Active Directory1 LDAP(AD1), Exchange 2003, SMS/NMS
server, 2 Oracle DB servers with 4 application servers and a SAN (these are
clustered). The backbone is in STAR topology and a ring surrounds the whole
area so data is able to flow both east and west. I also have 2 cores
switches for redundancy (core1 & core2).
They have told me now to setup a failover site which is in the same MAN but
uses one of the other LANs which I name LOCATION 2, I believe to be the
following :
I split up the core switches by placing the core2 at the LOCATION 2 with
the following servers (AD2, Exchange 2003, SMS/NMS, 1 Oracle DB server with 1
application server). NOw there will be a AUTOSWITCH over switch (which I am
still looking for) which will be placed on the backbone and will connect the
2 core switches to the backbone - this switch if it realizes that LOCATION 1
is down then it will automatically reroute the network flow to LOCATION 2.
Now I know that I need to connect LOCATION 1 & LOCATION 2 with a seperate
fiber so as to have replication between the servers ----here are the
questions
Do I need to connect a fiber from each server at LOCATION 1 to the same
server at LOCATION 2 or can I use a switch at both locations ??
How would I go about setting this up so that the server will replicate
between each other at the diff locations and so that there will not be a
duplicate of info ??
Now that I have driven everyone nuts
Thanks in Advance for any and all help
Peter
