15.3.1 Aspects that influence communication performance
This section discusses various aspects that have a significant influence on the
link performance.
Link bandwidth
The link bandwidth is the most obvious factor that affects performance. It is also
one of the key metrics used when provisioning the link. In storage environments,
the link bandwidth used should always be the guaranteed bandwidth from the

If the guaranteed bandwidth is anything less than a full Gigabit Ethernet, it needs
to be configured into the routers ...
