Applications

The Compaq EMU Assembly is used in mid-to-large-scale enterprise tape storage systems, particularly in Compaq's StorageWorks tape library and array product lines from the 1990s through early 2000s era. Redundant power supply modules like this one are critical components in high-availability storage configurations, providing failover power protection to prevent data loss and system downtime. These assemblies are commonly found in data centers, backup and archival systems, and automated tape libraries where continuous operation is essential. The redundant design ensures that if one power path fails, the other maintains full system operation without interruption.
