質問 67
A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.
Per the defined logical network configuration, there are two network adapters each used for:
Management traffic
vMotion traffic
iSCSI traffic
Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?
- A. Combine vMotion and Management traffic to make use of four adapters.
- B. Configure a dedicated TCP/IP stack for vMotion traffic.
- C. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
- D. Use Network I/O Control to define a reservation for vMotion traffic.
正解: C
解説:
https://kb.vmware.com/s/article/2007467
https://communities.vmware.com/t5/VMware-vSphere-Discussions/vmotion-load-balanced-across-multiple-uplinks-on-distributed/td-p/491336
https://www.virtuallyboring.com/multi-nic-vmotion/
We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernel interfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it for vMotion, you create a new stream. With more streams, there is greater bandwidth utilization.
