DELL 400-AJPU 1.2TB SAS 12Gb/s

This new Dell 400-AJPU is a 1.2TB internal hard drive with a 2.5 inch form factor. It connects via a SAS 12Gb/s interface and spins at 10000 RPM. The unit is designed for enterprise storage environments.

Enterprise storage users needing 10K SAS

The drive suits administrators who require 10000 RPM performance and a 12Gb/s SAS connection for compatible servers or arrays. It is not for buyers who need a different interface standard, a larger physical form factor, or a lower spindle speed for archival purposes.

12Gb/s SAS interface decides fit

The single specification that determines compatibility is the 12Gb/s SAS interface. Your controller or backplane must support this exact standard to use the drive. If the system uses a different interface, the part will not function.

Questions about this item

Does my server or storage array need a 12 Gb/s SAS backplane or controller for this 400-AJPU drive?

The drive uses a SAS 12 Gb/s interface, so the host system must provide a compatible SAS backplane or HBA that supports 12 Gb/s signalling.

Will this 1.2 TB 10000 RPM SAS drive work in a bay that currently holds 6 Gb/s SAS drives?

SAS 12 Gb/s drives are backward compatible with 6 Gb/s SAS backplanes; the drive will operate at the lower link speed.

How can I verify the drive is running at 10000 RPM and 12 Gb/s after installation?

Check the controller BIOS or management utility — it should report the negotiated link speed as 12 Gb/s and the spindle speed as 10000 RPM.
