Scenario 7

< Back | Next>

Scenario:

You are designing a vSphere environment that will utilize a distributed vSwitch that has two high-speed (10 Gbps) uplinks per ESXi host. It will provide networking for VMs, vMotion, and management. You intend to allow vMotion to maximize the utilization of available (unused) network bandwidth whenever hosts attempt to enter maintenance mode. However, you are concerned that uncontrolled network utilization by vMotion could cause competition with production VM network traffic and management traffic. You want to configure the distributed switch to accommodate your intention and concern. You want to test the configuration on a distributed virtual switch in your current vSphere environment, although it has only a single, 1 Gbps uplink per ESXi host.

Requirements:

• You need to configure network I/O control to ensure that vMotion network traffic is set with the lowest priority of all network traffic types during times of network contention.
• Do not change the priority of other types of network traffic.
• NOTE – Do not worry if the actual vMotion vmkernel port is not connected to the distributed virtual switch. Simply configure Network I/O Control to meet the requirements.

Environment Information:

• dvSwitch: dvSwitch0
