If we enable shadowing over a SAN
can be really efficient
with two copies of IB on two servers that access the SAN....
but this is not really a good thign for performance reason...
and having a shadow on the same machine is not a failover
tecnique valid in case of LAN failure or HW failure on the server.
Really he wants to simulate clustering...
