Hello,

we want deploy two database in clustering on W2000 with MCS and Oracle Fail Safe, and 8i over SAN storage.
The cluster have 2 nodes.
The node A with two instance: database A (8.1.6) in active mode, and database B (8.1.7) in pasive mode.
The node B with two instance: database B in active mode, and database A in pasive mode.

We have 4 questions:
1. ¿Is this configuration possible?
2. ¿Can we install two different Oracle versions (8.1.6 and 8.1.7) in the same machine?
3. ¿Can we protect the environment of fails in the storage controllers no redundant with another machine out of the cluster and the SAN in Standby mode with the two instance in the cluster?
4. ¿Where can we download the 8i version?

Thanks!! (Sorry my english)
