HPE SR932i-p SPDM Storage Controller P47184-B21

HPE SR932i‑p Gen11 x32 Lanes 8GB Wide Cache PCI SPDM Plug‑in Storage Controller P47184-B21

The HPE SR932i-p Gen11 x32 Lanes 8GB Wide Cache PCI SPDM Plug-in Storage Controller (P47184-B21) is a flagship component designed to deliver unparalleled storage performance, flexibility, and security for the latest generation of HPE ProLiant servers. This advanced RAID controller is crucial for modern data centers handling high-density storage, virtualized environments, and data-intensive applications.

Technical Specifications:

The P47184-B21 is built around a powerful architecture that maximizes I/O capabilities and data integrity:

• Host Interface: Utilizes a PCI Express 4.0 (PCIe Gen4) x16 interface, providing a massive bandwidth pipeline (up to 46GB/s bi-directional throughput) to the server’s CPU, essential for high-performance NVMe and SAS/SATA drives.
• Drive Support: It’s a tri-mode controller supporting 6Gb/s SATA, 24Gb/s SAS, and PCIe 4.0 (NVMe) drives, offering immense flexibility for connecting various storage devices. It can manage up to 32 direct-attached devices without an expander, and up to 238 drives with expanders.
• Cache: Features a generous 8GB DDR4 wide cache with integrated cache protection (Flash Backed Write-back Cache – FBWC), significantly improving write performance and protecting data in case of power loss.
• RAID Levels: Supports a comprehensive range of RAID levels including RAID 0, 1, 5, 6, 10, 50, 60, as well as RAID 1T and 10T, providing robust data redundancy and customizable performance profiles.
• Form Factor: Standard PCIe full-height, half-length plug-in card for easy installation.
• Security Features: Incorporates Hardware Root of Trust (HWRoT) for secure boot and firmware authentication, and DMTF SPDM (Security Protocol and Data Model) support for certificate-based authentication with HPE iLO6. This enhances the security posture against malicious attacks.
• Performance: Capable of up to 3.5 million IOPS and 24GB/s throughput from cache.

Advantages:

The HPE SR932i-p offers compelling benefits for demanding workloads:

• Extreme Performance: Leverages PCIe Gen4 and a wide cache to deliver industry-leading throughput and IOPS, crucial for accelerating databases, virtualization, and AI/ML applications.
• Enhanced Security: With HWRoT and SPDM, it provides a robust security framework for storage, protecting against unauthorized access and firmware tampering.
• Unmatched Flexibility: Tri-mode support (SAS/SATA/NVMe) and extensive RAID options allow for diverse storage configurations and future scalability.
• Optimized for NVMe: Fully unlocks the low-latency and high-throughput potential of NVMe SSDs.
• Simplified Management: Supports HPE Smart Storage Administrator (SSA) GUI/CLI, UEFI, and Redfish for intuitive storage management.

Applications:

This high-end storage controller is ideal for:

• Mission-Critical Databases: Accelerating OLTP and data warehousing with high IOPS and low latency.
• Large-Scale Virtualization: Supporting high VM density and improving performance for virtualized applications.
• Big Data Analytics: Enabling rapid access and processing of massive datasets.
• AI/Machine Learning: Providing the necessary storage backbone for computationally intensive AI/ML models.
• All-Flash Arrays (AFAs): Maximizing the performance of high-density flash storage solutions.
