HPE CTR RAID MR408i-p SAS 12G 4 GB CACHE

The HPE MR408i-p stands apart from typical RAID controllers by pairing a dedicated 4GB flash-backed cache with dual-mode SAS and NVMe connectivity, enabling mixed drive deployments without sacrificing performance or data integrity. Built for HPE ProLiant Gen10 Plus servers, it delivers enterprise-grade RAID acceleration in a compact Type-p module that installs directly into the server's dedicated storage slot.

Highlights

• Broadcom MegaRAID processor with PCIe 3.0 x8 host interface for low-latency throughput
• 4GB DDR4 cache with flash-backed write cache (FBWC) to protect data during power loss
• Supports RAID 0, 1, 5, 6, 10, 50, 60, and JBOD across up to 8 internal SAS, SATA, or NVMe drives
• Dual operating modes: RAID mode for hardware acceleration or HBA mode for software-defined storage
• Managed via HPE Smart Storage Administrator or Broadcom MegaRAID Storage Manager

In daily use

Administrators can mix high-speed NVMe drives with cost-effective SAS or SATA media, all behind a single controller. Online capacity expansion and RAID migration allow storage growth without downtime, while hot spare support keeps arrays resilient. The 12Gb/s SAS interface ensures fast rebuilds and consistent performance under heavy I/O.
