Storage controller HP MR408i-p Gen11 PCIe x8, 4GB cache, supports SATA III, internal memory 8192 MB

HP MR408i-p Gen11 is a plug-in storage controller designed for enterprise server arrays and storage subsystems. It connects via a PCIe x8 slot and provides a 4GB cache with 8192 MB internal memory to accelerate storage operations. The controller supports Serial ATA III (SATA III) drive interfaces and follows HPE Compute MR Controllers design and certifications. With physical dimensions of 222.3 × 252.4 × 65.1 mm, the MR408i-p Gen11 is intended for installation in compatible server chassis where reliable RAID-capable storage management is required.

Advantages

The MR408i-p Gen11 offers a hardware-based storage management solution with on-board cache and substantial internal memory to improve read/write responsiveness and reduce latency for common enterprise workloads. Its PCIe x8 interface provides high-bandwidth connectivity to the host system while maintaining a compact form factor. Support for SATA III ensures compatibility with a wide range of HDDs and SSDs used in server environments. The controller adheres to HPE Compute MR Controller certifications and integrates into ecosystems that rely on Broadcom MegaRAID-derived features and tools.

Suitable for

• RAID-managed server storage arrays in enterprise data centers
• Storage subsystems requiring SATA III drive support
• Virtualized environments where hardware RAID and cache improve performance
• Servers that accept PCIe x8 plug-in storage controllers

How to use

Install the MR408i-p Gen11 into a compatible server PCIe x8 slot following the server and HPE installation guidelines. Connect the controller to the storage backplane or drive cages that use SATA III interfaces. After physical installation, power on the server and configure the controller using the server management tools or the storage management utilities supported by HPE and Broadcom MegaRAID (refer to HPE QuickSpecs and product documentation for management software options). Create and manage RAID arrays as required, allocate cache policies, and verify that drives are recognised and healthy before placing the system into production.

Usage recommendations

Use the controller with server firmware and management software versions that are listed as supported in the HPE QuickSpecs. Match drive types and capacities within RAID arrays to avoid performance and rebuild penalties. Regularly monitor firmware updates and apply tested updates within maintenance windows to maintain compatibility and security.
