About the 405-AAIS
The Dell 405-AAIS is a Dell PERC H730P Mini Monolithic 2GB NV Cache RAID Controller designed to manage enterprise RAID storage across SAS, SATA, and NVMe drives. Engineered with dedicated I/O processing silicon and onboard cache, the 405-AAIS executes hardware RAID levels 0, 1, 5, 6, 10, 50, and 60 with battery-backed or flash-backed cache protection. In Dell's server line-up, 405-AAIS ensures data availability and write caching for mission-critical storage volumes.
Compatibility
The 405-AAIS controller installs into dedicated storage slots or PCIe risers on Dell PowerEdge servers including R740, R740XD, R640, R540. The 405-AAIS interfaces with internal hot-plug drive backplanes via SAS or SlimSAS cabling and manages drives mounted in appropriate chassis caddies. Supported operating systems on the 405-AAIS include VMware ESXi, Windows Server, and Linux distributions with Dell PERC driver support.
How to identify a genuine unit
Authentic Dell 405-AAIS PERC controllers display a serialized label showing DP/N 02PHG9, PERC branding, and Broadcom or LSI manufacturing markings. Within iDRAC under Storage Controllers, the 405-AAIS card enumerates with full firmware revision, battery or supercapacitor health telemetry, and connected virtual disk details.
Buying used
When sourcing a pre-owned 405-AAIS, inspect the card PCB for damaged surface passives or warped heatsink assemblies. Test the backup battery or supercapacitor pack on the 405-AAIS to ensure it holds a charge and reports healthy cache protection in iDRAC. Verify that all 405-AAIS SAS/NVMe physical channels detect attached drives without bus timeout errors.

FAQ
How does NV cache protect data during unexpected power cuts?
During an unexpected power loss, onboard supercapacitors power the transfer of unwritten DRAM cache data into permanent flash memory.
What is the difference between H730 and H730P?
The H730P features 2GB of cache (double the 1GB of standard H730) and an upgraded processor clock rate for higher IOPS.
