As depicted in Figure 9, we can solve the network single point of failure issue (for
Oracle data files) by using Direct NFS and configuring multiple NICs on the client
and the server. An alternative would be to use bonded NICs, but that does require
additional capability in the network. In addition (not shown here for simplicity) multiple
networks can be configured between the Oracle server and the NFS server to avoid
downtime in the event of network failure. Direct NFS can load-balance datafile activity
across these many connections. It can also survive a failure of all but the last working
path. However, if the client fails or the server fails, the database will shutdown.
