QuestionQ32

Designing the FlexPod Solution

Which MTU value should be set on VMware ESXi VMkernel ports and virtual switches in an FCoE boot-from-SAN environment?

  • A 9000
  • B 1500
  • C 1492
  • D 9216
Explanation

FCoE boot-from-SAN designs use jumbo-frame support, so ESXi VMkernel ports and virtual switches should be configured with an MTU of 9000. The supporting physical network must permit that MTU end to end; 9216 is commonly the network-fabric frame limit used to accommodate overhead, not the ESXi VMkernel/vSwitch setting.
