Dell PERC H840 External 12Gbps SAS PCIe 8GB Cache Hardware RAID Controller Adapter (405-AAMZ)

The Dell PERC H840 External 12Gbps SAS 8GB NV Flash-Backed PCIe Hardware RAID Controller Adapter (Dell Part Numbers: V5FKR / 0V5FKR / Dell Ordering SKU: 405-AAMZ) is an enterprise storage adapter designed to connect Dell PowerEdge server platforms to external SAS storage enclosures (such as Dell PowerVault ME4/ME5 series and MD-series expansion JBODs). Engineered for high-throughput external disk array management, this controller provides seamless expansion and hardware-level data redundancy.

Powered by Broadcom's dual-core SAS3516 ROC processor, the PERC H840 features 8 external 12Gb/s SAS ports across two mini-SAS HD (SFF-8644) connectors over a high-speed PCI Express 3.0 x8 host interface. Equipped with a massive 8GB DDR4 non-volatile (NV) cache buffer, it supports hardware RAID 0, 1, 5, 6, 10, 50, and 60 configurations, preserving dirty cache data during power disruptions via an integrated flash-backed cache module.
