Detailed Specifications
HPE Smart Array P408i-p SR Gen10 830824-B21 - 12 Gb/s SAS RAID Controller (2 GB Cache)
Overview
The HPE Smart Array P408i-p SR Gen10 (part number 830824-B21) is a plug-in PCIe storage controller designed for Gen10 servers that require internal SAS/SATA connectivity and enterprise-class RAID/HBA flexibility. It offers eight internal SAS lanes (across two mini-SAS ports) supporting 12 Gb/s SAS or 6 Gb/s SATA devices, with a 2 GB flash-backed write cache to optimise write performance in heavy-I/O or database-driven environments. It supports Mixed Mode (RAID + HBA) so you can configure some drives as RAID and some as pass-through HBA, making it ideal for servers handling a mix of legacy HDDs and SSDs. Fit this into a standard PCIe-3.0 x8 slot in a compatible HPE ProLiant Gen10 server, and use it as your internal storage controller for mission-critical workloads.
Key Features
Eight internal SAS lanes (2 × mini-SAS @ 12 Gb/s) let you attach SAS or SATA drives directly within the server chassis.
2 GB Flash-Backed Write Cache (FBWC) improves write latency and consistency for databases, VMs, and log-intensive workloads.
Mixed Mode support (RAID levels 0/1/5/6/10/50/60 & HBA pass-through) gives flexibility to combine high-performance RAID with direct-attached drives in one controller.
Encryption and SmartCache support: enables data-at-rest encryption on drives and SSD caching for hot-data acceleration (via licensed options) in enterprise Gen10 servers.
