IBM tested and supported Linux environments

This table shows IBM tested and supported Linux environments. For the supported distributions check the statements of the individual Linux distribution as some are out of service and will require extended support. You can obtain a Support Line contract for remote technical support or contract with a third party provider.

The listed distributions are 64-bit distributions; the Red Hat and SUSE distributions include the 31-bit emulation layer to run 31-bit software products. See the testing below and read the footnotes as well.
