About the 05-50085-00
05-50085-00 is Broadcom's next-generation 16-port internal PCIe 5.0 Tri-Mode hardware RAID controller, model MegaRAID 9660-16i. Powered by the SAS4116 RAID-on-Chip and 8GB of high-speed cache, it brings cutting-edge PCIe Gen5 x16 host connectivity to 24G SAS, 6G SATA, and Gen5 NVMe storage tiers. Delivering over 6 million random read IOPS and up to 28 GB/s bandwidth, it represents the industry benchmark for PCIe 5.0 enterprise storage.
Compatibility
Engineered for modern PCIe Gen5 enterprise servers, including 4th/5th Gen Intel Xeon Scalable and AMD EPYC 9004 systems. It requires a mechanical and electrical PCIe 5.0 x16 slot for full throughput. Drive backplane connectivity uses two internal SlimSAS SFF-8654 x8 connectors. It requires the CacheVault CVPM06 backup module for protected write caching.
How to identify a genuine unit
The board features a high-density low-profile PCB with a label reading Broadcom 05-50085-00 and MegaRAID 9660-16i. The heatsink is larger than previous generations to dissipate heat from the SAS4116 processor. In UEFI HII and StorCLI, the card reports PCIe 5.0 host bus negotiation and 8GB memory.
Buying used
Inspect PCIe 5.0 gold finger contacts for scratches or uneven wear. Verify that the passive heatsink thermal interface material is intact and that cooling fans in your server chassis provide adequate airflow. Confirm that the CacheVault CVPM06 power module is included.
