The Intel RAID Maintenance Free Backup Unit (AXXRMFBU5) is a cache data protection module for Intel RAID controllers that uses ultra-capacitors to secure cached write data during power outages without requiring battery maintenance.
Key features include maintenance-free ultra-capacitor technology, automatic health monitoring, hot-swappable design, LED status indicator and seamless integration with Intel RAID management software.
On power loss, the unit’s ultra-capacitors supply enough energy to flush cached write data to disk, preserving data integrity until full system power is restored.
AXXRMFBU5 is compatible with Intel RAID controllers in the Intel Server and RSTe families that support the Maintenance Free Backup Unit interface—refer to Intel’s compatibility matrix for specific models.
