Past end of service

10/100

Little or no runway

Support Runway Score

Every tracked Dell Mainframe Disk Library (MDL) SKU group is past Dell end of service life (last group Jun 2017). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure.
