FREQUENTLY ASKED QUESTIONS ABOUT 872493-003
What is the difference between 872493-003, 872487-B21 and 872745-001?
They identify the same physical drive under different HPE numbering schemes. This page, 872493-003, is the assembly number: the identifier for the manufactured drive assembly as built and labeled. 872487-B21 is the option number, used when the drive is ordered as a boxed product. 872745-001 is the spare number, used for service replacement. This family also includes seven OEM drive models, all listed in the cross-reference block on this page.
What does an assembly part number mean on the drive label?
An assembly part number identifies the drive as HPE built and labeled it, including the carrier and firmware configuration. It is the number stamped on the physical unit and returned by HPE PartSurfer lookups, which is why it often does not match the number used to order the drive. Seeing 872493-003 on a label confirms the unit is the 4TB SAS 12G 7.2K LFF drive described on this page, supplied with an HPE Smart Carrier.
Why does my drive label show a different manufacturer number?
Drives in this family are also marked with an OEM model number, which is the disk manufacturer's own designation for the specific mechanism used in the build. HPE sources this 4TB 7.2K SAS drive from more than one manufacturer, so seven OEM models map to the same HPE assembly. All are the same orderable product with the same 12 Gb/s SAS interface, 3.5-inch form factor and digitally signed firmware.
What are the key specifications for this drive?
It is a 4TB hard drive with a 7,200 rpm spindle speed, formatted at 512 bytes per sector. The interface is Serial Attached SCSI 3, with one SAS port rated at 12 Gb/s. The form factor is 3.5-inch LFF (8.9 cm), fitting a 3.5-inch LFF bay, and the drive is hot-swap capable. It ships with an HPE Smart Carrier and is part of the HPE Business Critical product line.
Which HPE servers accept this drive?
This drive is listed as compatible with the ProLiant DL60, DL80, DL120, DL160, DL180, DL360, DL380 and DL388 Gen9 models, plus DL360 Gen10 and DL380 Gen10.
