FREQUENTLY ASKED QUESTIONS ABOUT 507129-003
What is the difference between 507129-003, 507127-B21 and 507284-001?
They identify the same physical 300GB 6G SAS 10K SFF drive under different HPE numbering schemes. This page, 507129-003, is the generic part number, the number HPE uses to identify the drive independent of how it was packaged. 507127-B21 is the option part number, the boxed configure or upgrade kit ordered against a server. 507284-001 is the spare part number used for service replacement. The hardware is identical in each case.
What other part numbers refer to this same drive?
Beyond the numbers named above, this family also includes 11 assembly revisions, 16 OEM drive models, one further generic part number and one alternate part number, all listed in the cross-reference block on this page. An assembly part number identifies a specific build revision of the drive and its attached tray. An OEM model number is the manufacturer's own designation for the bare drive mechanism inside the HPE carrier.
Which servers accept this drive?
It is supported in HPE ProLiant SFF systems including BL20p G4, BL25p G2, BL45p G2, BL460c G1/G5/G6/G7, BL465c G1/G5/G6/G7, BL480c, BL620c G7, BL680c G5/G7, BL685c G1/G5/G6/G7, BL860c, BL870c, DL1000, DL120 G7, DL160 G6, DL165 G7, DL170e/h G6, DL180 G6, DL320 G6, DL360 G4p through G7, DL365 G1/G5, DL370 G6, DL380 G4 through G7, DL385 G1 through G7, DL580 G3/G4/G5/G7, DL585 G1 through G7, DL785 G5/G6, DL980 G7, ML350 G5/G6, ML370 G4/G5/G6, ML570 G3/G4, SL390s G7 and WS460c G6.
Does this drive include a caddy or tray?
Yes. The hot-swap tray is included and attached to the drive, so no separate carrier is required. The drive is a hot-plug unit intended for server and storage bays, meaning it can be inserted or removed while the system is running where the controller and enclosure support that operation. Physical dimensions are 0.591" high by 2.75" wide in the 2.5-inch low profile form factor.
What does dual port 6G SAS mean for configuration?
The drive uses the SAS (Serial Attached SCSI) interface with an external data transfer rate of 6 Gb/s. Dual port means the drive presents two independent SAS ports, which allows redundant paths to the drive in enclosures and controllers designed for multipath access. In single-path configurations the drive operates normally through one port, so it can be mixed into standard SFF SAS bays without special handling.
