Capacity and interface

The Dell 400-AUSL is a 2.4TB 2.5-inch SAS hard drive spinning at 10000 RPM with a 12Gb/s interface standard. It uses a 512e disk format and arrives as a bare drive with hot-plug capability for compatible Dell systems.

Server and array builders

This drive suits administrators expanding SAS-based storage arrays or replacing failed units in Dell PowerEdge servers where 512e support is confirmed. Buyers whose operating environment does not support 512e drives, or who require a non-SAS interface, should look elsewhere.

512e format constraint

The single specification that decides fitment is the 512e disk format; VMware does not support it, Windows Server 2008 R2 or later and some Linux distributions do, while 4Kn drives need Windows Server 2012 and UEFI boot.

Questions about this item

Does the 12Gb/s SAS interface actually run at 12Gb/s in this drive?

The drive uses a SAS 6Gb/s interface, so the 12Gb/s standard is supported by the controller but the drive itself caps at 6Gb/s.

Will this 2.5-inch drive fit a standard 3.5-inch desktop bay?

The drive has a 2.5-inch form factor and requires a 2.5-inch bay or an adapter bracket to mount in a 3.5-inch slot.

Is any jumper or firmware step needed before hot-swapping this Dell drive?

The drive supports hot-plug operation and uses a 512e format; no jumpers are required, but the OS must support 512e drives.
