About the 405-AAJW
The Dell 405-AAJW is a Dell HBA330 12Gb/s SAS Host Bus Adapter (PCIe Adapter) delivering non-RAID SAS pass-through connectivity across 2x Internal Mini-SAS HD (SFF-8643) over PCIe 3.0 x8. Built with Broadcom SAS controller silicon on the 405-AAJW, it provides direct target communication for software-defined storage, JBOD shelves, and tape automation. In Dell's storage ecosystem, 405-AAJW enables high-throughput host-to-enclosure data pathways.
Compatibility
The 405-AAJW installs into PCIe slots or dedicated storage bays on Dell PowerEdge servers including R730, R740, R640, R540. The 405-AAJW connects to internal drive backplanes or external PowerVault enclosures over SAS cabling without RAID volume overhead, enabling software-defined storage stacks to manage drives directly.
How to identify a genuine unit
Authentic Dell 405-AAJW SAS HBAs carry a serialized label displaying DP/N 0J70W9, SAS controller branding, and Dell regulatory approvals. In iDRAC under Storage Controllers, the 405-AAJW adapter identifies as an authentic Dell HBA with active firmware and device mapping.
Buying used
When sourcing a pre-owned 405-AAJW, inspect the physical PCIe edge contacts and SAS connector ports for damaged pins. Verify that onboard passive heatsinks on the 405-AAJW are firmly seated, and test in iDRAC to confirm that all connected drives enumerate in pass-through mode.
