Dell 400-ANUT 4 TB SAS drive

This Dell 400-ANUT is a 4 TB internal hard drive built for Dell PowerEdge servers. It uses a 12 Gb/s SAS interface and spins at 7 200 RPM to deliver fast disk access for nearline workloads. The 3.5 inch form factor fits standard enterprise drive bays. It is suited for administrators expanding storage capacity in compatible Dell systems.

Hot-swap 3.5 inch SAS construction

The drive is hot-swappable and hot-pluggable, allowing replacement without powering down the server. Its bare-drive packaging means it slides directly into a caddy or backplane for immediate integration. The SAS connector supports dual-port operation for path redundancy in supported chassis. This design simplifies maintenance and reduces downtime in production environments.

12 Gb/s SAS interface decides fit

The single specification that determines compatibility is the 12 Gb/s SAS interface; the drive will only operate in controllers and backplanes that support this standard. It is validated for PowerEdge R230, R330, R430, R530, R730, R730XD, T330, T430 and T630 servers. Systems lacking a 12 Gb/s SAS connection cannot use this drive.

Questions about this item

What does the SAS 12Gb/s interface cap the transfer rate at in practice?

The SAS 12Gb/s interface caps the theoretical transfer rate at 12Gb/s. Actual throughput depends on the controller and system workload.

What physical space and mounting does the 3.5" form factor need?

It fits a standard 3.5-inch internal drive bay. Hot-swap trays in compatible PowerEdge servers accept it directly.

How is the drive installed, and what step is often missed?

Slide the bare drive into a hot-swap carrier, lock the lever, and insert it into a powered-on bay. People often forget to seat the carrier fully until it clicks.
