OpenShift Data Foundation¶

If you are looking at OpenShift Platform Plus (OPP) and are targeting ODF to be your storage provider, here's how to install it.

Jumbo Frames Required

The storage network must support jumbo frames (MTU 9000) end-to-end for ODF to perform properly. Ensure switches, node NICs, and storage interfaces are all configured for MTU 9000 before deploying ODF. See Storage Network prerequisites and the Storage Network NNCP example for configuration details.
