Gigabit Ethernet really necessary?

From the lights on my gigabit ethernet switch, it looks like the server really does have a gigabit ethernet NIC, but the players and reader don't.

If only the server has gigabit ethernet, doesn't seem like it would really be necessary to have gigabit switches and wiring... right?

If the server can only talk to 100mbit devices, then the communications are only working at 100mbit speeds... yes?

Or are my players old... maybe the new ones have true gigabit-E?

The new servers are gigabit ethernet (not the old one). It makes perfect sense to have a gigabit switch even if the clients operate at 100 mbits. The switch does the translation from 1000 mbit to/from 100 mbit, so the server would be able to talk to more clients if it had a 1000 mbit connection. Given that HD streams can use up to 35 mbit/s, it would only take two of these streams (gotta leave some headroom on Ethernet) to swamp a server's 100mbit connection. But if it had a gigabit connection connected to a gigabit switch, then many more HD streams are possible.

Basically, the server's bandwidth doesn't get dumbed down depending on what it is talking to.
 
In a situation where somebody has lets say 11 zones of playback, a server running 100 meg would be overwhelmed and you would not get correct playback since the nic on the server is a bottleneck.

Since the server has no bottleneck, then there is no issue. we had tested 28 zones of playback with superbit titles all coming from one drive (only two drives in the server) and it ran fine.

So server has different needs than player, player will only ever pull 38 Meg (HD)
 
I do wonder if the server can load faster than 100mbit data rate. I have had as many as 4 readers running at once. I am sure the drive would hit the ceiling before the gigE, but 100mbit seems like it might be the first limit you would run into in bulk loading.
