Dell Mainframe Disk Library (MDL) — data protection. End-of-sale (Dell EOL) and end-of-standard-support (EOSS) dates from Dell’s published End-of-Life list (Dell KB 000185734).

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.
