Table 11‑3. Support of Jumbo Frames
Type of iSCSI Adapters Jumbo Frames Support
Software iSCSI Supported
Dependent Hardware iSCSI Supported. Check with vendor.
Independent Hardware iSCSI Supported. Check with vendor.
Enable Jumbo Frames for Software and Dependent Hardware
iSCSI
To enable Jumbo Frames for software and dependent hardware iSCSI adapters in the
vSphere Web Client, change the default value of the maximum transmission units (MTU) parameter.
You change the MTU parameter on the vSphere switch that you use for iSCSI traffic. For more
information, see the vSphere Networking documentation.
Procedure
1 Browse to the host in the vSphere Web Client navigator.
2 Click the Configure tab.
3 Under Networking, click Virtual switches, and select the vSphere switch that you want to modify
from the list.
4 Click the Edit settings icon.
5 On the Properties page, change the MTU parameter.
This step sets the MTU for all physical NICs on that standard switch. The MTU value should be set to
the largest MTU size among all NICs connected to the standard switch. ESXi supports the MTU size
up to 9000 Bytes.
Enable Jumbo Frames for Independent Hardware iSCSI
To enable Jumbo Frames for independent hardware iSCSI adapters in the vSphere Web Client, change
the default value of the maximum transmission units (MTU) parameter.
Use the Advanced Options settings to change the MTU parameter for the iSCSI HBA.
Procedure
1 Browse to the host in the vSphere Web Client navigator.
2 Click the Configure tab.
3 Under Storage, click Storage Adapters, and select the independent hardware iSCSI adapter from
the list of adapters.
4 Under Adapter Details, click the Advanced Options tab and click Edit.
5 Change the value of the MTU parameter.
ESXi supports the MTU size up to 9000 Bytes.
