The Broadcom 05-50134-25 is a MegaRAID 9520-8i server RAID controller built on the SAS3808 processor, presenting eight internal ports through a single SFF-8654 connector to a PCIe 4.0 x8 host interface. The record lists 8GB of cache memory with CVPM05 cache-backup compatibility, support for RAID 0, 1 and 10 plus JBOD mode, and up to 16 SAS or SATA devices, with NVMe device support recorded as zero. It is a low-profile card measuring 6.1in by 2.7in, rated from 0C to 55C, with a stated MTBF above 3000000 hours at 40C and a 12Gb/s device-side transfer rate. The legacy LSI part reference for this controller is LSI3808.

Server RAID controllers of this class provide hardware mirroring and striping for the boot and data volumes of rack and tower servers, taking cache management and rebuild handling off the host CPU and surviving a power loss when paired with a cache-backup module. A RAID 0, 1 and 10 set without parity levels targets configurations where write performance and rebuild time matter more than capacity efficiency - boot mirrors, database log volumes and virtualisation datastores. JBOD mode lets the same card pass drives straight through to a software-defined storage layer such as vSAN, Ceph or ZFS, which is how many operators deploy these cards today. Buyers should source the cache-backup module separately and confirm availability, since the CVPM05 supercapacitor unit is what makes write-back caching safe to enable.
