Sun Microsystems 3EM21500AA Sun MSC-2 Server Hardware / Parts

Sun Microsystems part number 3EM21500AA is identified as an MSC-2 mass storage controller assembly, used within Suns server and storage platforms to manage connected disk or tape storage devices. Mass storage controller cards of this type typically bridge a servers internal bus to external or internal SCSI/Fibre Channel storage, handling I/O between the host system and attached drives. Suns 3EM-prefixed part numbering is associated with server and storage subsystem components from the Sun server range of that era, and the MSC-2 designation points to a specific controller revision within that family. This unit is supplied as a genuine pull from a decommissioned Sun system, suitable for maintaining or repairing existing Sun server/storage deployments where the original controller has failed or needs replacing. Given the age and specificity of Suns internal part numbering, buyers should confirm exact host-system compatibility before ordering, as controller cards of this type are frequently tied to a narrow range of chassis and backplane revisions.
