Dear Group,

We are trying to setup a RAC environment in our shop. One proposal is like this:

We have node A1, A2, B1, B2, and san box S1,S2

A1,A2, S1 is on primary site, B1,B2,S2 is on disaster recovery site,

A1,A2 is connecting to S1, B1,B2 is connecting to S2, we will connect A1,A2,B1,B2 through fiber glass chennel and S1,S2 are synchronized. In this way, we can put A1,A2,B1,B2 all in service, because S1,S2 holds same datebase(two databases but synchornized)

Any comments?

Thanks for your help.

How many miles between data center AS1 and data center BS2? Look
up the details for extended RAC clusters and see if you qualify?

What version of Oracle? It matters.

Systems like this have been built but not the way you are describing
it. A third site, generally NFS mount or iSCSI, is required to hold the
voting disk and thus you need two separate fibre networks.
