Dear Al,
Please read my initial mail again. I have said that the 2 SAN Box are in
Sinc.
To clarify the lethency period etc. these 2 sites are 1.5 kms away and
connection between site is through fiber cables.
Now I hope that u get my requirement.
Cluster was proposed by Raj which I felt was a valid solution.
Should u need any further clarification please feel free contact me.
Regards,
Rajnish

Your original post was not detailed enough to answer the question.
More information about requirements is needed. You've given a possible
goal
but no idea or background as to why or what the acceptable solution
could
look like.
Could you deploy a third node to the cluster? Yes and no. It depends
on
your environment and how much latency exists between the data
repositories,
the WAN links etc. (assuming this is across a WAN). Just adding a third
node
to the cluster may not achieve what you want to accomplish if the data
isn't
replicated fast enough.
You have not specified what level of service needs to be available
during
any disaster event. You haven't specified the distances etc.
Al

Dear Raj,
You are right that Cluster is an ideal solution but Remember that I need
some kind of cluster in which it will be 4 nodes and 2 storage.
If you see my initial diagram I have 2 SAN Box's which are already set
in
Sync with each other.
The 2nd SAN Box was introduced to have a failover.
Now tell me has you and one tried DR in this kind of scenario.
Regards,
Rajnish

Dear Friends,
I have the following situation with exchange 2000 running in a cluster
Site 1 Site 2
Server A <---->Server B Server C
| |
SAN Box |---------------------------------------| SAN Box (Replication)
I have one site in which my exchange server (Server A & Server B) are
running in a cluster and data is stored in SAN Storage (Data, Logs,
Qurun)
Now I need to add another DISTATER RECOVERY SITE. We have successfully
configured the SAN replication between these sites for (Data & Logs).
Is their a way I can make Server C as exchange server to service my
client
request in case of any failure.
Await your reply.
Regards,
Rajnish
