Explanation

For optimal iSCSI performance on a Dell Unity XT array, configuring jumbo frames is recommended. Jumbo frames allow for larger packets of data to be sent over the network, reducing the CPU load on both the storage array and the host, and improving overall throughput. Configuring jumbo frames typically involves setting the MTU (Maximum Transmission Unit) to 9000 bytes on all network devices along the path.
