About the HPE MR416i-p Gen11 8GB Cache PCIe Storage Controller
The HPE MR416i-p Gen11 8GB Cache PCIe Storage Controller is a PCIe-based storage acceleration module designed for direct installation in HPE ProLiant Gen11 servers. This controller operates over a PCIe Gen 4 x8 host interface and manages up to 240 drives when expanders are deployed, making it suitable for organizations requiring high-capacity, high-performance storage subsystems. The unit features 8 GB of cache memory protected by Flash-Backed Write Cache (FBWC) with capacitor backup, ensuring data integrity during power transitions and system recovery scenarios.
The MR416i-p Gen11 connects to 12 Gb/s SAS and 6 Gb/s SATA drives across 16 internal ports, supporting HPE SmartDrive SAS HDD, SAS SSD, SATA HDD, and SATA SSD technologies. The controller implements RAID levels 0, 1, 5, 6, 10, 50, and 60, delivering redundancy and performance configurations across diverse workloads. Storage architects and IT procurement teams favor this HPE solution because it integrates seamlessly with HPE iLO (Integrated Lights-Out) management infrastructure and operates reliably across VMware ESXi, Windows Server, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server environments. The Broadcom MegaRAID architecture underlying the controller provides proven reliability in mission-critical data center deployments.
The HPE MR416i-p Gen11 (part number P47777-B21) represents a strategic investment for organizations standardizing on HPE infrastructure and requiring enterprise-grade storage acceleration without external enclosure dependencies. Whether you are expanding existing ProLiant Gen11 deployments or designing new storage-intensive systems, this controller delivers the cache capacity and port density needed for demanding SAN and NAS applications.
