Howdy,
I'd like to confirm my understanding of how ng_one2many works: Using a
setup like http://bsdvault.net/sections.php?op=printpage&artid=98), I
think that:
* with an unmanaged switch I'll be able to effectively double the
outgoing bandwidth on a given server, though my incoming bandwidth
will remain at 100Mbit
* with a managed switch that supports link aggregation I'll be able to
effectively double the bandwidth in both directions
* on a hub, of course, there would be no bandwidth increase
i.e., this will be a good way to increase the performance of an NFS file
server to multiple simultaneous clients on an network with unmanaged
switches. The NFS server is currently network I/O limited - the vinum
array runs almost four times as fast as I can serve the files, according
to bonnie++ benchmarking runs. The NFS traffic is fairly async, being
mostly reads.
Does that sound about right?
