About Omneon MediaGrid - Harmonic Inc

Jumbo Frames Support
Jumbo frames are a feature that allows for larger transmission sizes of Ethernet frames over a
network. Omneon MediaGrid supports jumbo frames; however, every device on your network
between Omneon MediaGrid and the client (including the client itself) must also support jumbo
frames, with a common packet size, to take advantage of this feature. Network performance is severely
impaired otherwise.
Jumbo frames may improve transfer performance between Omneon MediaGrid and other devices on
the network in some cases. However, an improvement will not always be obtained, depending on the
devices’ ability to process data relative to the maximum network transfer speed available.
The Network Switches are enabled by default. Refer to Configuring a ContentServer to enable
jumbo frames on the remaining Omneon MediaGrid devices.
Omneon strongly recommends that the Omneon MediaGrid be initially set up and tested with all
other parts of the system infrastructure with jumbo frames disabled, to ensure correct functionality,
before enabling jumbo frames.
Omneon MediaGrid File System Driver Software
Omneon MediaGrid file system driver software, installed on customer supplied desktops,
communicates with the system to store and retrieve files. See the Omneon MediaGrid Release Notes for
your particular client platform for the latest supported client operating systems.
