HPE 405132-B21 – Smart Array P400 256MB RAID Controller
Overview
The HPE 405132-B21 Smart Array P400 is a PCI Express SAS RAID controller designed for HPE ProLiant servers to manage internal disk storage with hardware RAID support. It provides centralized control of multiple SAS and SATA drives to improve performance and data protection in enterprise environments.
It supports hardware RAID levels including 0, 1, 5, and 10, enabling flexible configurations for performance or redundancy depending on workload requirements. The controller is equipped with a 256MB cache to accelerate I/O operations and improve response times in storage-intensive systems.
It is commonly used in mid-range enterprise servers where internal storage arrays are required, particularly in rack and tower ProLiant systems. The controller connects via PCIe x8 and manages multiple internal drives through SAS interfaces.
It is designed for legacy ProLiant platforms and remains widely used in refurbished and replacement enterprise server environments.
Typical Deployment Scenarios
Used in HPE ProLiant servers requiring internal RAID storage for virtualization, file services, and database workloads. Common in enterprise environments where SAS-based disk arrays are deployed for performance and redundancy. Also used in legacy infrastructure upgrades and refurbished server deployments.
