## Summary description

Peripheral controller HP 804398-B21 is a server peripheral interface component by HP designed to manage and connect external devices. As an HP-branded controller module (MPN 804398-B21), it provides hardware-level control for attached peripherals and is intended for integration into compatible HP server systems to enable reliable I/O management and peripheral connectivity.

## Long description

HP Peripheral controller 804398-B21 is a server peripheral interface module designed to manage and connect external storage devices in compatible HP server platforms. The module provides hardware-level I/O control for externally attached drives and occupies a PCIe expansion slot. It supports 12 Gb/s SAS connectivity, PCIe 3.0 host interface, and offers functionality for RAID 0, 1, 5 and 10 as well as Mixed Mode operation that allows RAID and HBA simultaneously. The controller includes eight external SAS lanes for connection to external disk enclosures and supports software-defined storage (SDS) deployments. Optional encryption for data-at-rest is available through the Smart Array SR Secure Encryption capability.
Advantages
This HP peripheral controller delivers enterprise-class SAS connectivity at a cost-effective price point while providing hardware RAID capabilities and HBA flexibility in a single card. Built-in support for 12 Gb/s SAS and PCIe 3.0 enables high-throughput connections to external JBODs and advanced storage arrays. The Mixed Mode operation reduces the need for an additional controller by supporting both RAID volumes and pass-through HBA connections concurrently. Integrated management and encryption options help preserve data integrity and meet regulatory requirements for protected data.
Suitable for
 Connecting external SAS or SATA drives in external enclosures (JBODs) to HPE ProLiant Gen10 servers
 Basic RAID configurations (RAID 0, 1, 5, 10) for capacity or redundancy
 Software-defined storage (SDS) setups requiring cost-effective external storage connectivity
 Environments needing a mix of RAID-managed volumes and HBA pass-through access
 Deployments that require optional data-at-rest encryption for regulatory compliance
Key specifications
 Interface to host: PCIe 3.0 (occupies a PCIe expansion slot)
 External ports: eight external SAS lanes for connection to external enclosures
 SAS speed: 12 Gb/s SAS support for external devices
 RAID support: RAID levels 0, 1, 5, 10
 Operation modes: Mixed Mode (RAID and HBA concurrently)
 Encryption: data-at-rest encryption supported via Smart Array SR Secure Encryption (optional license)
 Management: compatible with HPE Smart Storage Administrator (SSA) and UEFI storage configuration tools
How to use
Install the controller into a free PCIe expansion slot on a compatible HP server following the server and module installation guidelines. Connect external SAS or SATA drives by attaching SAS cables from the controller's external lanes to the target disk enclosure or JBOD. Use the server's UEFI storage configuration or HPE Smart Storage Administrator (SSA) to create and configure RAID volumes, enable Mixed Mode if both RAID and HBA are required, and apply encryption licenses when needed. Ensure firmware and management software are kept up to date according to HP/HPE maintenance recommendations.
Usage recommendations
For predictable performance and compatibility, use 12 Gb/s-capable external storage enclosures and certified SAS cables. When deploying encryption, verify license availability and test restore procedures. For mixed-mode deployments, plan device mapping carefully so that RAID arrays and HBA-attached devices do not conflict. Regularly monitor drive health with available management tools and apply firmware updates to maintain stability and security.
