This read-only object mirrors the `onBoardMemoryCheckNeeded` property of a catalog definition describing which storage-management features a particular disk-controller type supports inside Cisco UCS Manager's internal information model, exposed here as a boolean true/false flag for this disk-controller type definition. This TruthValue states whether UCS Manager needs to actively verify the onboard cache-memory health of the controller type described by this disk-controller type definition before trusting it in production. If the definition for a MegaRAID-based SAS controller reports this as true, a memory self-test failure on that controller would be treated as a hard fault rather than ignored.
