geographically dispersed clustering.

Hello All:

I need to come up with a solution for a DR project involving two
separate servers on one location which need to failover to two other
serversabout 15 miles away in another location
System 1: OS is 2000, running SQL (app that needs to failover)
System 2: OS is 2003 running exchange.(app that needs to failover)

My question is two fold:
1. Assuming the hardware is in place on both ends (servers, storage
etc) and a way to replicate the data between the two environments, what
can I use to HOT failover these servers between the two locations.
2. Same scenario without any way to replicate data, but all hardware is
in place. Host mirroring is not an option.

Any help will be appreciated

Thanks.

If you've got the right geographically dispersed clustering solution, the
cluster should just simply failover between sites. The trick is usually at
the storage level trying to make your replication work properly after the
failover.

If you do not have any way to replicate the data, you will not be doing a
geographically dispersed cluster. You would need to look into some sort of
tape backup/restore plan instead.

Regards,
John
