FREQUENTLY ASKED QUESTIONS ABOUT 599476-001
What is the difference between 599476-001, 507127-B21 and 507284-001?
They identify the same physical drive at different points in HPE's numbering. This page, 599476-001, is an assembly part number: the number printed on the assembled drive and tray as built. 507127-B21 is the orderable option kit, and 507284-001 is the spare part number used for service replacement. This family also includes ten further assembly revisions, 16 OEM drive models, two generic part numbers and one alternate part number, all listed in the cross-reference block on this page. An OEM model number is the drive manufacturer's own designation for the mechanism inside the HPE carrier.
Which kit do I need — 507127-B21 or 652564-B21?
Both kits deliver this 300GB 6G SAS 10K drive. 652564-B21 is an Enterprise product line kit using the SC carrier and is supported on Gen8, Gen9 and Gen10 servers. 507127-B21 is the kit associated with this page's assembly number, 599476-001. Check the compatibility list on each kit's page against your specific server model and generation, and match the carrier type to the drive bays already in your chassis before ordering.
Does this drive come with a caddy or tray?
Yes. The hot-swap tray is included and attached to the drive as supplied under 599476-001. That is what makes it an assembly rather than a bare mechanism — the number covers the drive and its carrier together. Because it is a hot-plug device, it is designed to be inserted and removed from a powered server or storage unit bay without shutting the system down, subject to your controller and array configuration.
Which servers accept 599476-001?
Supported platforms include ProLiant 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, DL160se G6, DL165 G7, DL170e G6, DL170h G6, DL180 G6, DL320 G6, DL360 G4p/G5/G6/G7, DL365 G1/G5, DL370 G6, DL380 G4/G5/G6/G7, DL385 G1/G2/G5/G5p/G6/G7, DL580 G3/G4/G5/G7, DL585 G1/G2/G5/G6/G7, DL785 G5/G6, DL980 G7, ML350 G5/G6, ML370 G4/G5/G6, ML570 G3/G4, SL390s G7 and WS460c G6.
What do the interface and speed figures mean here?
The drive uses a SAS (Serial Attached SCSI) interface with a 6 Gb/s external data transfer rate and a dual port connection. Rotational speed is 10,000 rpm. Capacity is 300GB. Those four figures, together with the 2.5-inch low profile form factor, are the values to compare against a drive label or PartSurfer entry when confirming that a module in hand matches this assembly number.
