What jumbo frames are

Jumbo frames are larger than standard frames and require fewer frames. Therefore, you can reduce the CPU processing overhead by using jumbo frames with your network interfaces. Particularly, by using jumbo frames with a Gigabit or 10 Gigabit Ethernet infrastructure, you can significantly improve performance, depending on the network traffic.

Jumbo frames are packets that are longer than the standard Ethernet (IEEE 802.3) frame size of 1,518 bytes. The frame size definition for jumbo frames is vendor-specific because jumbo frames are not part of the IEEE standard. The most commonly used jumbo frame size is 9,018 bytes.

Jumbo frames can be used for all Gigabit and 10 Gigabit Ethernet interfaces that are supported on your storage system. The interfaces must be operating at or above 1,000 Mbps.

You can set up jumbo frames on your storage system in the following two ways:
