NIC Teaming theory questions

Hello!

Windows Server 2012 NIC Teaming (LBFO) Deployment and Management (http://www.microsoft.com/en-us/download/details.aspx?id=30160) says:

"3.4    Interactions between Configurations and Load distribution algorithms
3.4.1    Switch Independent configuration / Address Hash distribution

This configuration will send packets using all active team members distributing the load through the use of the selected level of address hashing (defaults to using TCP ports and IP addresses to seed the hash function).

Because a given IP address can only be associated with a single MAC address for routing purposes, this mode receives inbound traffic on only one team member (the primary member). This means that the inbound traffic cannot exceed the bandwidth of one team memberno matter how much is getting sent."


Q1)Am I correct that a user after connecting to a server will be able to save data to the server  with the "bandwidth of one team member" but read using aggregated bandwidth of all team memebers?

"3.4.2    Switch Independent configuration / Hyper-V Port distribution

This configuration will send packets using all active team members distributing the load based on the Hyper-V switch port number.  Each Hyper-V port will be bandwidth limited to not more than one team member’s bandwidth because the port is affinitized to exactly one team member at any point in time.

Because each VM (Hyper-V port) is associated with a single team member, this mode receives inbound traffic for the VM on the same team member the VM’s outbound traffic uses.  This also allows maximum use of Virtual Machine Queues (VMQs) for better performance over all. "

This mode is best used for teaming under the Hyper-V switch when

  1. The number of VMs well-exceeds the number of team members; and
  2. A restriction of a VM to not greater than one NIC’s bandwidth is acceptable"

Q2) If "each VM (Hyper-V port) is associated with a single team member"  than more than one VM per Hyper-V port will result in a bandwidth < 1 team member...Why this mode is best used forThe number of VMs well-exceeds the number of team members?

Q3) Don't these words  - "each VM (Hyper-V port) is associated with a single team member" - mean there can't be more than one VM per Nic (team member)?  ...I know that they don't...Just trying to perceive the meaning of them...

Thank you in advance,

Michael
