Dell has extensive Linux expertise through our dedicated Linux engineering and technical support teams. The following Linux distributions are supported through collaborative support agreements between Dell and our respective Linux partners. Please see our support overview page here. Additional Linux information is found on our Dell Linux pages here and on our Dell Linux solutions page here.
Many 3rd party vendors publish hardware compatibility lists to document the HW platforms that their products are certified for. Links to those HCL lists are provided below for reference. For those distributions that are not covered by ProSupport, vendor support agreements and subscriptions are available through our Software and Peripherals (found here) organization (except for Asianux).
Note: We acknowledge the wide use of CentOS on Dell systems and understand that it's a community developed derivative of the Dell-supported Red Hat Enterprise Linux. Support for this OS is available directly from the CentOS communuty at their website here.
