Bandwidth Policies vs. Bandwidth Shaping

VM Profile Bandwidth Shaping differs from VM Policy Bandwidth Control.

VM Profile Bandwidth Shaping (see “VM Profiles” on page 169) is configured per VM group and is enforced on the server by a virtual switch in the hypervisor. Shaping is unidirectional and limits traffic transmitted from the virtual switch to the G8124. Shaping is performed prior to transmit VM Policy Bandwidth Control. If the egress traffic for a virtual switch port group exceeds shaping parameters, the traffic is dropped by the virtual switch in the hypervisor. Shaping uses server CPU resources, but prevents extra traffic from consuming bandwidth between the server and the G8124. Shaping is not supported simultaneously on the same ports as vNICs.

VM Policy Bandwidth Control is configured per VE, and can be set independently for transmit traffic. Bandwidth policies are enforced by the G8124. VE traffic that exceeds configured levels is dropped by the switch upon ingress. Setting txrate uses ACL resources on the switch.

Bandwidth shaping and bandwidth policies can be used separately or in concert.
