The NFS virtual partition used for the target is the small piece of the disk shown in the figure, it resides at /opt, it

will be further discussed in Section 4, “Setting up an NFS Root File System on a Host.”

Several targets can access each of these NFS root file systems via the ethernet. More than one target can share an

NFS root file system, or each target can have only one. For this paper, each target will have only one NFS root file

system.

The host can access each target via a serial connection, or via ethernet, once the target is started. In this figure, we

show two targets, each can be either an ADS or a Sandpoint board, each is connected to its unique NFS root file

system via a network, and the host can communicate with either target.
