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.
