HPE Broadcom MegaRAID 12G Controller

This HPE Broadcom MegaRAID 12G Controller stands apart from typical RAID cards by combining Broadcom's SAS3916 Tri-Mode silicon with 8GB of flash-backed DDR4 cache, delivering both 12Gb/s SAS and 6Gb/s SATA throughput plus NVMe readiness in a single PCIe 4.0 x16 slot. It is built for HPE ProLiant Gen10 Plus servers where data integrity and mixed-drive flexibility are non-negotiable.

Highlights

• Tri-Mode support: SAS, SATA, and NVMe drives on the same controller.
• 16 internal ports via four SFF-8643 connectors, expandable with SAS expanders.
• Hardware RAID levels 0, 1, 5, 6, 10, 50, and 60 with up to 64 logical drives.
• CacheVault flash backup protects the 8GB DDR4 write cache without a battery.
• PCIe 4.0 x16 host interface eliminates bottlenecks for high-speed storage.
• Secure Boot and self-encrypting drive (SED) support for hardened deployments.
• Managed through MegaRAID Storage Manager, StorCLI, or HII.

In daily use

Administrators can mix SAS and SATA drives for tiered storage, then add NVMe devices later without swapping controllers. The CacheVault supercapacitor flushes cached writes to flash on power loss, so performance stays high without the maintenance of a traditional battery. Broad OS support covers Windows Server, Linux, and VMware ESXi, making it a drop-in upgrade for many ProLiant Gen10 Plus workloads.
