Dell SAS 12Gbp/s Hba External Controller Card

The Dell 405-AADZ is a host bus adapter that equips a PowerEdge R730 with four external 12 Gb/s SAS links through its SFF-8644 ports. It creates a direct path between the server and external SAS storage, delivering reliable throughput without the overhead of a network fabric.

Installing the card is straightforward. It occupies a single PCI Express slot, then uses standard SAS and SCSI protocols so the operating system recognizes new drives immediately. No zoning or switch configuration is required, which lets you bring extra capacity online quickly and keep workloads running smoothly.

The adapter is well suited to situations where storage needs can change overnight. A virtualization cluster that has exhausted internal bays, a backup server that requires a dedicated tape library, or a data analytics node that must access a growing archive can all gain room to expand by cabling an external SAS enclosure.

Because the card runs Dell firmware, it appears in the same update and monitoring tools already used for PowerEdge servers. This consistency streamlines maintenance and helps prevent configuration drift across the environment.
