Enabling Jumbo Frame to lmprove Network Performance
Jumbo Frames: is a frame with a payload greater than the standard maximum transmission unit (MTU) of 1,500 bytes. Jumbo frames can carry up to 9000 bytes of payload. Enabling jumbo frames can improve network performance by making data transmissions more efficient, and with less protocol overhead. But before enabling Jumbo frame, you need to consider the network must support Jumbo frames end-to-end and configure the entire network path, including: VMkernel adaptor Virtual switches Hosts NICs Physical switches Routers Storage devices You don’t have to use jumbo frames everywhere, and in many cases, they are not needed; With the granularity vSphere networking offers, it is possible to have different MTU settings in your environment. For example, you may want to configure the storage connectivity to use jumbo frames while the virtual machines use the standard 1500 MTU. The most common application of jumbo frames is on IP storage networks such as iSCSI, ...
