## Long description

HPE MR408i-p Gen11 x8 Lanes 4GB Cache PCI SPDM Plug-in Storage Controller is a server storage controller based on Broadcom MegaRAID technology designed for data center and virtualized environments. It supports Serial ATA III drives, provides hardware security features including SPDM support, and is available in standard PCI HH/HL and OCP NIC 3.0 form factors. The controller offers high bandwidth and RAID capabilities suitable for mission-critical workloads.
Advantages
The controller combines PCIe Gen4 performance with MegaRAID functionality to deliver reduced RAID rebuild times, high I/O throughput and reliable data protection. It includes Hardware Root of Trust to help protect firmware, supports certificate-based authentication via SPDM with compatible management, and can be managed using MegaRAID Storage Administrator, StorCLI, UEFI and Redfish interfaces. Its plug-in design and standard form factors enable straightforward integration into existing server platforms.
Suitable for
 Enterprise data centers requiring RAID storage and high bandwidth
 Virtualized environments using HBA / pass-through or RAID modes
 Servers needing hardware-backed firmware security and certificate-based authentication
 Systems using Serial ATA III drives for internal storage

 Internal cache: 4 GB
 Memory (controller module): 8192 MB listed in product details
 Form factors: Standard PCI HH/HL and OCP NIC 3.0 compatible
 Security: Hardware Root of Trust (HWRoT) and SPDM support for certificate-based authentication
 Management interfaces: MegaRAID Storage Administrator (MRSA), StorCLI, UEFI, Redfish
 Physical dimensions (approx.): width 222.3 mm, depth 252.4 mm, height 65.1 mm
How to use
Install the MR408i-p controller into a compatible PCIe slot (HH/HL or OCP NIC 3.0 as supported by your server). Connect supported Serial ATA III drives to the server backplane or drive connectors per chassis instructions. Configure RAID arrays or HBA/pass-through mode using the MegaRAID Storage Administrator or StorCLI during system setup. Ensure firmware and management tools are up to date and enable SPDM certificate authentication with HPE iLO 6 or other supported management to utilize hardware security features.
Usage recommendations
Use the controller in systems with current firmware and management stack to benefit from HWRoT and SPDM security. Select appropriate RAID levels and ensure regular backups; for high write workloads consider configurations and drive types that match performance requirements. Verify compatibility of Serial ATA III drives with your server backplane before deployment.
