How are you planning to make NFS redundant?
we plan to use a disk array for storage and two head nodes to provide NFS access. the array has two controllers which provide redundant service to the host (active/passive). each host is connected to both controllers (4 cables in total), redundantly to each other, and redundantly to the network.
each head will run Solaris with Sun Cluster HA-NFS software to provide active/passive NFS service to clients with transparent failover. this allows us to perform maintenance on the array and either NFS head without affecting service, and in case or hardware or software failure of the active head, the system will failover to the passive head.
