## Public Network Hardware: Requirements When Using Jumbo Frames

If you use Scalable Data Services and jumbo frames on your public network, ensure that the Maximum Transfer Unit (MTU) of the private network is the same size or larger than the MTU of your public network.

Note - Scalable services cannot forward public network packets that are larger than the MTU size of the private network. The scalable services application instances will not receive those packets.

Consider the following information when configuring jumbo frames:

- The maximum MTU size for an InfiniBand interface is typically less than the maximum MTU size for an Ethernet interface.

- If you use switches in your private network, ensure they are configured to the MTU sizes of the private network interfaces.

For information about how to configure jumbo frames, see the documentation that shipped with your network interface card. See your Oracle Solaris OS documentation or contact your Oracle sales representative for other Oracle Solaris restrictions.
