Lenovo SE445 V3 RAID 940-8i Supercap Cable | RAID Controller Cable

Preserve cached write data when the unexpected happens. The Lenovo SE445 V3 RAID 940-8i Supercap Cable is designed for the SE445 V3 RAID 940-8i RAID environment, where cache protection matters as much as controller performance. By supporting the supercap connection, it helps maintain data integrity during power interruptions and gives the controller the backup path it needs to safely flush protected cache. For infrastructure teams, that means fewer compromises between performance and protection. In RAID deployments where write caching is enabled, backup power for cache is not optional—it is part of the data protection chain. This cable is built for that role in Lenovo-supported systems, helping ensure the supercap assembly is properly connected and ready to support protected cache operations. Choose this cable when the cost of cache loss is higher than the cost of doing it right. It is a targeted component for environments that depend on consistent RAID behavior, controlled shutdown handling, and dependable write protection under fault conditions.
