Setting a port’s maximum bandwidth to 100 percent allows that
partition to use bandwidth that is not used by other partitions.
This would apply if one or more of the other partitions were using
less than their relative bandwidth setting.
If a partition’s maximum setting is less than 100 percent, it is
limited to that percentage, and the unused bandwidth of other
partitions is not available to it if it hits its maximum bandwidth
limit.
Oversubscription can be especially valuable in an environment
with a mixture of NIC and storage and vMotion
®
traffic. It might be
advantageous to have the NIC partition used by vMotion
consume all unused bandwidth. Setting the vMotion partition to a
maximum bandwidth of 100 percent ensures that the vMotion
port dynamically consumes all bandwidth not being used by the
other functions.

For each partition, use the
Partition
drop-down list to enable, disable, or
change the function type. You can only enable one function type on each
partition at a time.
NOTE
When bandwidth settings exist for both Switch Independent
Partitioning and DCBX,
DCBX takes precedence over Switch
Independent Partitioning
. DCBX sets the bandwidth for iSCSI and NIC
traffic, and then Switch Independent Partitioning sets the bandwidth for
the NIC partitions by dividing the NIC bandwidth allocated by DCBX.
For more information, see
“Interoperation of Bandwidth Settings for
DCBX and Switch Independent Partitioning” on page 121
.
NOTE
Enabling one function type automatically disables the other type (or
mode).
