405-AANM Dell PERC HBA330 PCIe 3.0 x8 Storage Controller

Low-Profile 12Gb/s SAS Host Bus Adapter for Dense Server Storage Expansion with the 405-AANM

The 405-AANM is a Dell low-profile PCIe SAS HBA engineered to add internal 12Gb/s SAS lanes to modern rack servers where predictable, OS-controlled storage behavior is required. Built on the Broadcom SAS3008 controller, the 405-AANM operates as a pass-through adapter rather than a hardware RAID device, enabling direct exposure of drives to the host for consistent discovery, monitoring, and lifecycle management across fleets.

Using a PCIe 3.0 x8 host interface and an internal SFF-8643 connection, the 405-AANM integrates cleanly with SAS backplanes for HDD and SSD attachment while preserving CPU and memory resources for application workloads. This architecture aligns well with software-defined storage and cluster-managed RAID, where control planes expect transparent device access, stable latency characteristics, and straightforward expansion without introducing proprietary RAID metadata. The low-profile form factor supports dense platforms and maintains airflow and serviceability in constrained chassis.

Why Choose the 405-AANM?

Choosing the 405-AANM provides an enterprise-ready path to scale internal SAS connectivity while keeping storage policy in the operating system or clustered storage layer. The adapter’s density-to-performance profile suits virtualisation hosts and capacity nodes that need additional backplane lanes without the operational overhead of hardware RAID configuration. With the 405-AANM, architects can standardize on a consistent HBA model to simplify qualification, spares strategy, and cross-node behavior in mixed workload environments.

Dell designs this class of I/O adapter for predictable integration with enterprise server platforms, emphasizing compatibility, sustained operation under data centre thermals, and alignment with standard PCIe and SAS cabling practices. The result is a deployment-friendly component that supports controlled scaling and repeatable builds.

Key Applications:

• Server storage expansion for internal SAS backplanes
• Software-defined storage and cluster-managed RAID
• Virtualisation hosts requiring additional SAS connectivity
• HDD/SSD attachment for capacity and archival nodes
