Dell N2024 Switch IP bandwidth questions.

Routing -> IP -> IP Configuration
    Band    1000000       default 10000
     A single one gigabit connection is 1,000,000 Kbps if my internet lookup is correct.
     The default value of 10,000 seems to be low for even a single gigabit connection.
     If for each device on this switch the value could be 1,000,000 kbps per pair of devices on dedicated ports that can be communicating concurrently.  When port aggregation is involved and there are sufficent sources/targets multiples of 1,000,000 Kbps would also appear to be appropriate.  This vlan is probably only going to have one part time user dealing with multiple devices primarily serially.  Therefore I believe a setting of 1000000 would be the proper bandwidth setting.  Am I correct?
     
     Second question; if the total configured bandwidth for all vlans exceeds the max 10,000,000 could result in conflict should there be sufficient concurrent traffic be a problem?  I accept that some requests may need to be delayed when this limit is exceeded and do not consider that alone to be a problem.  Another way of asking this is would keeping the total for all vlans to a total of 10,000,000 or less meaning no one vlan can affect any other vlan be better or worse than having a total over 10,000,000 where multiple vlans will be affected when the limit is reached?  In the first case vlans will be affected more often only from their own users.  In the second case when some vlans are inactive others get the potential benefit of additional bandwidth.
     
     IPv6 interfaces do not have a bandwidth value.  Is this a Vlan bandwidth (IPv4&6) or an IPv4 interface ONLY bandwidth?  If IPv4 only; where does IPv6 get bandwidth?
