About the 405-AANT
The Dell 405-AANT is a Dell 12Gbps SAS HBA Dual Port External PCIe Controller delivering non-RAID SAS pass-through connectivity across 2x External Mini-SAS HD (SFF-8644) over PCIe 3.0 x8. Built with Broadcom SAS controller silicon on the 405-AANT, it provides direct target communication for software-defined storage, JBOD shelves, and tape automation. In Dell's storage ecosystem, 405-AANT enables high-throughput host-to-enclosure data pathways.
Compatibility
The 405-AANT installs into PCIe slots or dedicated storage bays on Dell PowerEdge servers including R740, R640, R750, MD1400. The 405-AANT 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-AANT SAS HBAs carry a serialized label displaying DP/N 0T93GD, SAS controller branding, and Dell regulatory approvals. In iDRAC under Storage Controllers, the 405-AANT adapter identifies as an authentic Dell HBA with active firmware and device mapping.
Buying used
When sourcing a pre-owned 405-AANT, inspect the physical PCIe edge contacts and SAS connector ports for damaged pins. Verify that onboard passive heatsinks on the 405-AANT are firmly seated, and test in iDRAC to confirm that all connected drives enumerate in pass-through mode.

Works together
How the Dell 405-AANT connects to servers, storage and the network: 1 way, with the hardware on each path.
Direct-attached SAS
12Gb SAS uses Mini-SAS HD (SFF-8644) connectors; older 6Gb gear uses Mini-SAS (SFF-8088). Adapter cables exist, but the link runs at the slower speed.
