IBM FlashSystem 840
Relic 2U FlashSystem 840 reference for old compatibility, warranty, release-note, parts, and migration searches that should now point toward replacement planning.
FlashSystem 840 is a relic now, but it is still worth a real page because installed-base notes, old firmware references, and compatibility searches still use the 840 name. The page should move a buyer away from expansion thinking and toward replacement planning.
Do not use modern FlashCore Module assumptions for FlashSystem 840. This is a pre-FCM generation, so the useful work is identification, risk assessment, support history, and migration planning.
