People Also Asked (PAA)
Q1: Can I use the Dell 400-AUST in a standard desktop PC?
A: Generally, no. This drive uses a SAS (Serial Attached SCSI) interface. Standard motherboards use SATA. To use this in a desktop, you would need a dedicated SAS HBA (Host Bus Adapter) controller.

A: This specific part number typically refers to the bare drive. However, in many enterprise retail kits, it may come pre-mounted. Always verify with your vendor if the PowerEdge tray is included.
Q3: What does “Hot-Plug” mean for this drive?
A: Hot-plug (or hot-swappable) means the drive can be removed or inserted while the server is running, provided your server backplane and OS support it. This is a standard feature for Dell PowerEdge systems.
