Dell HBA355i Front Controller

This Dell HBA355i front controller is an internal host bus adapter for PowerEdge storage configurations that use SAS/SATA drive backplanes. It provides direct HBA connectivity for supported 12Gb/s SAS and SATA drives rather than hardware RAID array management, making it appropriate for pass-through storage layouts and software-defined storage configurations. Compatibility depends on the server model, front-controller mounting position, internal backplane type, SAS/SATA cable set, drive bay layout, and whether the system is configured for an HBA355i front storage controller rather than a PERC RAID controller.
