6.2.5 Step 5: Configure Jumbo Frames
In order for Jumbo Frames to work, it must be enabled end-to-end on both the physical and virtual
network infrastructure, or the frame size will fall back to standard frames. PS Series arrays have Jumbo
Frames enabled by default. Verify with your network administrator that the network fabric has Jumbo
Frames enabled.
For Jumbo Frames to be enabled for iSCSI traffic on an ESXi host, it must be enabled on the distributed
vSwitch used for iSCSI and on all VMkernel ports that will carry iSCSI traffic.
To enable Jumbo Frames on the vDS:
1. Start from the data center object under the Networking inventory view, select the Related Objects
tab, select the Distributed Switches button, and select the Edit distributed switch setting icon
(the fifth icon on the toolbar).
2. On the Edit Setting page, select Advanced.
3. Change the MTU setting from the default of 1500 to 9000.
