## Long description

The HPE Smart Array P431 Controller is a low‑profile PCIe 3.0 x8 SAS RAID controller designed for select HPE ProLiant Gen8 rack and tower servers. It supports 12 Gb/s SAS links, offers two external SAS ports and up to 200 drives per controller when expanded, and includes 4 GB Flash Backed Write Cache (FBWC) for improved data retention and write performance. The controller supports multiple RAID levels including RAID 1, RAID 6 (ADG), and RAID 60 (ADG), and is compatible with other HPE Smart Array controllers for simplified upgrades.
Advantages
The P431 provides increased storage throughput and scalability for growing workloads, with support for an end‑to‑end 12 Gb/s SAS environment. Integrated 4 GB FBWC preserves data in the event of power loss and enables online RAID level migration and global online spare features to reduce downtime. Optional HP Secure Encryption protects data at rest when enabled. The controller also includes optimizations for SSD performance (HP SSD Smart Path) and predictive spare activation to speed rebuilds.
Suitable for
Enterprise and SMB servers requiring high-performance SAS storage
Environments needing hardware RAID (RAID 1, RAID 6 ADG, RAID 60 ADG)
Systems that require encrypted data-at-rest support (with optional HP Secure Encryption)
Storage expansion scenarios up to hundreds of drives using external enclosures
