Overview

The Dell PERC H840P RAID Controller (405-AANN) is an enterprise-grade storage adapter engineered for Dell EMC PowerEdge rack servers. Delivered in a low-profile plug-in card form factor, it slots into a PCI Express x8 interface and provides advanced hardware RAID capabilities for managing external storage arrays. This offloads RAID processing from the host server CPU, freeing compute resources for applications while the controller handles data protection, parity calculations, and drive management.

Designed specifically for the PowerEdge R440, R540, R640, R6415, R740, R740xd, and R7415 platforms, the H840P supports hard disk drives, solid state drives, and disk arrays. Its low-profile design accommodates the tight internal clearances of 1U and 2U rack-mount servers. For data center administrators building or expanding Dell-based storage infrastructure, the H840P provides a validated, supported path to reliable RAID protection and improved storage throughput.
