## Summary description

HP 804394R-B21 is a PCI Express 3.0 RAID controller providing 12 Gbit/s data transfer and support for SAS storage drives. It implements RAID levels 0, 1, 5 and 10 and connects via PCIe to host systems. Designed for server environments, it is compatible with HPE ProLiant DL360 Gen10, DL380 Gen10 and DL560 Gen10 for hardware RAID, data redundancy and performance optimization.

## Long description

HP 804394R-B21 is a PCIe 3.0 RAID controller that provides 12 Gbit/s SAS connectivity for internal server storage. Designed for HPE ProLiant Gen10 systems, the controller supports hardware RAID levels 0, 1, 5 and 10 and connects to the host system via a PCI Express slot. It enables data redundancy and performance optimization for SAS and SATA drives in rack servers and supports mixed mode operation for combined RAID and host bus adapter functions.
Advantages
The controller offers enterprise-class reliability and 12 Gbit/s throughput for internal storage, enabling faster data transfers and reduced I/O bottlenecks compared with lower-speed adapters. It supports multiple RAID levels to balance redundancy and performance and provides Mixed Mode operation to run RAID and HBA simultaneously. Management and configuration are simplified through standard server tools and HPE software interfaces, allowing scripting and remote configuration in modern server environments.
Suitable for
Server storage acceleration and I/O consolidation in HPE ProLiant Gen10 racks
Environments requiring hardware RAID 0, 1, 5 or 10 for redundancy and performance
Systems using SAS or SATA internal drives up to 12 Gbit/s
Deployments that require mixed RAID and HBA operation without additional controllers
Key specifications
Host interface: PCI Express 3.0
Maximum link speed: 12 Gbit/s per SAS lane
Supported RAID levels: 0, 1, 5, 10
SAS support for internal SAS and SATA drives
Mixed Mode: simultaneous RAID and HBA operation
Eight internal SAS lanes (for internal drive connectivity)
How to use
Install the controller into a free PCIe expansion slot in a compatible server and connect internal SAS or SATA drives to the controller’s internal lanes following the server manufacturer’s hardware installation guide. After physical installation, boot to the server UEFI or operating system and use HPE Smart Storage Administrator (SSA) or the UEFI storage configuration tool to create and configure RAID arrays. Mixed Mode can be enabled in controller settings when both RAID volumes and direct-attached drives are required.
Usage recommendations
For reliable operation, use certified HPE ProLiant Gen10 servers and HPE-supported drive models. Configure RAID level according to the required balance between performance and data protection: RAID 0 for maximum throughput without redundancy, RAID 1 for mirroring, RAID 5 for efficient redundancy with parity, and RAID 10 for combined performance and protection. Keep controller firmware and management software updated and consider enabling encryption or drive health monitoring features where supported.
