Really bad things happen when you confise bits and bytes.

Tape drive bandwidth is quoted in bytes per second. LTO speed is 120MB/s.
Big B. Bytes. The "163MB/s"  figure is "expected speed with compression" 

Network performance is quoted in bites per second, or Mbps. Little b.

Thus, 100Mbps network will only sustain 12MB/s write speed. Even single GE 
is not enough to sustain LTO-4 performance.
