HPE Smart Array P816i-a SR Gen10 Controller
The HPE Smart Array P816i-a SR Gen10 Controller is a high-performance PCIe storage accelerator designed for modern HPE Gen10 servers. Engineered to deliver 12Gb/s SAS throughput with a 4 GB flash-backed write cache (FBWC), it brings exceptional reliability, resilience, and speed to enterprise workloads. This controller operates in Mixed Mode, enabling simultaneous RAID and HBA operations to maximize flexibility for both traditional storage arrays and direct-attached server configurations. Whether you’re running databases, virtualization, or heavy I/O applications, the P816i-a Gen10 is built to optimize I/O latency, improve data protection, and simplify storage management across complex deployments.
- 12 Gb/s SAS with advanced data path efficiency: The P816i-a Gen10 leverages the high-speed 12Gb/s SAS interface to deliver sustained throughput and low-latency I/O for demanding workloads. Its architecture is optimized to handle large, sequential transfers and concurrent I/O streams, helping to reduce bottlenecks in busy data centers. This makes it well-suited for databases, analytics, and virtualization environments where consistent performance is critical.
- PCIe 3.0 integration for robust bandwidth: Built to plug into PCIe 3.0 infrastructure, the controller achieves excellent bandwidth headroom within standard server platforms. This ensures that multiple disks or drive enclosures connected to the controller can operate at high speed without contending for I/O resources with other peripherals. The PCIe 3.0 interface is a key factor in achieving predictable latency and scalable performance as storage requirements grow.
- 4 GB FBWC for superior data integrity: The flash-backed write cache (FBWC) provides a protective write-back mechanism that safeguards data during unexpected power loss or system outages. By maintaining a durable cache in flash memory, the P816i-a Gen10 helps minimize write data loss, accelerating write-heavy workloads and enabling more reliable throughput during peak I/O operations. This feature is essential for mission-critical applications that require strong data protection guarantees.
- Mixed Mode operation for maximum flexibility: Mixed Mode allows the controller to perform RAID operations while simultaneously presenting direct access (HBA) to attached disks. This dual capability is ideal for environments that need to support both traditional RAID arrays and pass-through disk access for certain servers or virtual machines. Mixed Mode reduces the need for separate controllers and simplifies management when diverse storage access patterns exist in a single chassis or rack.
- Supports advanced RAID configurations and enterprise resilience: The P816i-a Gen10 is designed to support a range of RAID levels and storage configurations, enabling administrators to tailor protection and performance to the workload. With robust data protection features, hot-swappable components, and enterprise-grade reliability, this controller helps organizations build scalable storage pools that can grow with business requirements while maintaining data integrity and recoverability during drive failures or rebuilds.

How to Install HPE Smart Array P816i-a SR Gen10 Controller
Preparing for installation involves ensuring you have power disconnected and proper static grounding. The following steps outline a straightforward installation process designed to minimize downtime while maximizing card performance and reliability. Always refer to your server’s service manual for specific slot placement and cabling guidelines, and ensure compatible drive types and cabling are used to prevent performance bottlenecks.
- Power down the server and remove the chassis cover. Ground yourself and any tools to prevent electrostatic discharge, then locate an available PCIe slot with enough clearance for the P816i-a Gen10 controller and its heat dissipation profile.
- Insert the P816i-a Gen10 card firmly into the chosen PCIe slot, ensuring that the connectors are seated completely. Secure the card with the chassis screw or retention mechanism as required by your server model.
- Attach SAS or SATA data cables to the controller’s ports and connect the other ends to your drive enclosures or backplane as dictated by your storage architecture. Use high-quality cables and avoid excessive bending to maintain signal integrity.
- Power on the server and access the system firmware or management console. Install or update the HPE Smart Storage Administrator (SSA) or integrated management tools to recognize the new controller and to configure the FBWC and cache settings.
- Initialize and configure your storage in SSA: define logical arrays (RAID groups), assign hot spares, and set up mixed-mode if you plan to use both RAID and pass-through. Validate that all connected drives are detected and that the cache policy aligns with your protection and performance goals.
- Verify successful boot and run a basic storage test to confirm that the controller is functioning as expected. Monitor for any firmware or driver updates that may enhance compatibility and performance, and apply them according to HPE guidelines.
- Document your configuration details, including RAID levels, cache settings, and drive mappings, to simplify future maintenance and upgrades. Regularly check for firmware updates and backup configurations to maintain data protection and system resilience.
Frequently Asked Questions
- What is the primary use case for the HPE Smart Array P816i-a SR Gen10 Controller? The P816i-a Gen10 is designed to maximize storage performance and reliability in HPE Gen10 servers. It supports 12Gb/s SAS with a robust 4 GB FBWC, enabling efficient handling of high I/O workloads such as databases, virtualization, and enterprise applications. Its mixed-mode capability provides flexibility for environments that require both RAID protection and direct disk access, reducing the need for multiple controllers in a single system.
- What advantages does FBWC bring to this controller? The 4 GB FBWC provides a fast, flash-backed cache that preserves write data during power interruptions. This reduces the risk of data loss, shortens rebuild times after drive failures, and enhances overall write performance under peak load. FBWC helps maintain data integrity and accelerates write-heavy transactions essential for business-critical workloads.
- Can I use the P816i-a Gen10 in non-HPE systems? This controller is designed for HPE ProLiant Gen10 servers and related HPE storage architectures. While some compatible components might exist in generic environments, optimal performance and full feature support (including FBWC and Mixed Mode) are typically realized within HPE systems and software ecosystems. Always consult official HPE compatibility matrices before attempting non-HPE deployments.
- What RAID levels are supported by this controller? The P816i-a Gen10 supports a range of RAID configurations intended for enterprise reliability and performance. These often include common levels such as RAID 0, 1, 5, 6, 10, 50, and 60, optimized for mixed workloads and data protection. Always verify the exact RAID level support for your specific firmware version and SSA configuration to ensure it meets your redundancy and performance goals.
- How do I optimize performance with Mixed Mode? Mixed Mode enables RAID operations while exposing disk pass-through access to hosts or virtual machines. To optimize performance, balance the number of logical drive mappings with the workload mix. For databases and I/O-intensive apps, consider larger stripe sizes and appropriate cache policies. Regularly review your cache settings and monitor I/O latency to adjust configurations as workloads evolve.
- Where can I find firmware and driver updates for the P816i-a Gen10? Updates are typically available through the HPE support site, including SSA and iLO integration. Keeping firmware and drivers up to date improves stability, compatibility, and performance with newer operating systems and storage configurations. Plan periodic checks and apply updates in a controlled maintenance window to minimize disruption.
