Question about Jumbo Frames

[nogi]

I had another thread about the speed issues that I have been having with the N3200S and RAID5. I have enabled Jumbo frames (4k) on the N3200 and on my NICs and am achieving ~14-15MB/s in windows transfer. PC to PC I am getting closer to 30MB/s.

The only other Jumbo Frame setting on the N3200S is 7k but my cards don't have a 7k option. They have a 6k or 8k option. What would happen if both my NICs were set to use 8k Jumbo frames and the N3200S was set to use 7k Jumbo frames? Would I get data corruption?

The conclusion from that article

1. Jumbo frames require gigabit Ethernet.
2. The highest frame size for a connection is the lowest end-to-end maximum frame size.
3. Gigabit Ethernet Layer 2 switches forward or drop jumbo frames; they don't fragment.
4. Fragmentation is a Layer 3 (routing) function.
5. TCP can adjust frame size between different devices. UDP can't.
6. Using jumbo frames for low latency applications (gaming, VoIP) can be counterproductive
7. Bigger isn't necessarily better. Jumbo frame sizes need to be matched to device computing power.

So, you should be able to use different frame size on your network.
