RAID controller HP Enterprise HPE SmartArray P408i-a SR Gen10 — PCIe x8, 12 Gbit/s, SATA/SAS, hardware RAID levels 0/1/5/6/10/50/60

HPE SmartArray P408i-a SR Gen10 is a hardware RAID controller designed for enterprise-class servers. It connects via a PCI Express x8 host interface and supports both Serial ATA (SATA) and Serial Attached SCSI (SAS) drives at up to 12 Gbit/s. The controller implements multiple hardware RAID levels — including RAID 0, 1, 5, 6, 10, 50 and 60 — to balance performance and data protection for storage consolidation, virtualization and database workloads.

Advantages

The HPE SmartArray P408i-a SR Gen10 provides dedicated hardware RAID processing to offload parity and mirroring operations from the host CPU, improving overall system performance. Support for 12 Gbit/s SATA and SAS links enables higher throughput with modern drives. The variety of supported RAID levels allows administrators to choose configurations optimized for either redundancy or speed. The PCIe x8 interface ensures a wide host connection suitable for enterprise server backplanes and storage enclosures.

Suitable for

• Storage consolidation in rack or blade servers
• Virtualization platforms requiring reliable RAID
• Database servers with mixed read/write workloads
• High-capacity direct-attached storage arrays

Key specifications

• Host interface: PCI Express x8
• Drive interface compatibility: SATA and SAS
• Link speed: up to 12 Gbit/s per supported drive connection
• Supported hardware RAID levels: 0, 1, 5, 6, 10, 50, 60
• Form factor: server add-in card (PCIe)

How to use

Install the P408i-a SR Gen10 into an available PCIe x8 slot in a compatible HPE Gen10 server or appropriate chassis following server manufacturer instructions. Connect supported SATA or SAS drives to the server backplane or drive cages that route to the controller. Configure RAID arrays using the server's setup utility or HPE management firmware during system boot, selecting the desired RAID level and stripe size according to workload requirements. After array creation, initialize and format logical volumes within the operating system and monitor array health using HPE management tools.

Recommendations

For best results, use enterprise-class SATA or SAS drives certified for server use and ensure firmware compatibility with the HPE Gen10 platform. Choose RAID levels based on required balance of redundancy and performance: RAID 6 or 60 for higher fault tolerance in large arrays, RAID 10 for lower-latency mixed workloads, and RAID 5 or 50 where capacity efficiency is a priority. Regularly monitor drive health and perform backups in addition to RAID protection.
