It is the server backend for the nbd network block device driver that's in the Linux kernel. nbd can be used to have a filesystem stored on another machine. It does provide a block device, not a file system; so unless you put a clustering filesystem on top of it, you can't access it simultaneously from more than one client. Use NFS or a real cluster FS (such as ocfs2) if you want to do this. nbd-server can export a file (which may contain a filesystem image) or a partition. Swapping over nbd is possible as well, though it's said not to be safe against OOM and should not be used for that case. nbd-server also has a copy-on-write mode where changes are saved to a separate file and thrown away when the connection closes. The package also contains the nbd-client tools, which you need to configure the nbd devices on the client side.
