Virtual Channel Settings - HP Surestore 6164 - Switch Reference Manual

Virtual Channel Settings

46
The switch provides the ability to tune it in a specific application, by
configuring the parameters for its eight virtual channels. Note that the first
two virtual channels are reserved for switch internal functions and are not
user-configurable.
The default virtual channel settings have already been optimized for switch
performance. Changing the default values can improve switch
performance, but it can also degrade performance. Do not change these
settings without fully understanding the effects of the changes.
