FREQUENTLY ASKED QUESTIONS ABOUT 507129-004
What is the difference between 507129-004, 507127-B21 and 507284-001?
All three refer to the same physical drive. 507129-004, this page, is a generic part number used to identify the drive itself. 507127-B21 is an option kit part number, the form the drive is ordered in as a factory or field-installable option. 507284-001 is the spare part number used for service replacement. 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 number identifies a specific build revision of the drive and carrier; an OEM model number is the drive manufacturer's own product designation.
Which kit do I need — 507127-B21 or 537809-B21?
Both 507127-B21 and 537809-B21 are option kits that supply this 300GB 6G dual port SAS 10K SFF drive with a hot-plug tray. Which one applies depends on the server platform you are populating, so check the compatibility list published on each kit's page against your exact server model and generation before ordering. The drive itself is identical between the two kits, including capacity, rotational speed, interface and form factor.
Does this drive include a carrier for hot-plug installation?
Yes. The hot-swap tray is included and attached to the drive, so no separate caddy or carrier is required for supported SFF hot-plug bays. The assembly is a 2.5-inch low profile form factor measuring 0.591" high and 2.75" wide, which matches standard HPE SFF drive bays on the supported ProLiant BL, DL, ML and SL platforms listed for this part.
What performance and interface does this drive provide?
It is a SAS (Serial Attached SCSI) hard drive with a dual port interface and an external data transfer rate of 6 Gb/s. Rotational speed is 10,000 rpm and usable capacity is 300GB. The dual port design allows two paths to the drive, which is used in redundant controller and multipath storage configurations. It is classified as a hard drive for server or storage unit use in a hot-plug bay.
Which servers accept this drive?
Supported systems include 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 G6, DL180 G6, DL320 G6, DL360 G4p/G5/G6/G7, DL365 G1/G5, DL370 G6, DL380 G4/G5/G6/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.
