FREQUENTLY ASKED QUESTIONS ABOUT EG0300FBDBR
What is the difference between EG0300FBDBR, 507127-B21 and 507284-001?
All three identify the same physical drive. EG0300FBDBR, the number on this page, is an OEM drive model number: the identifier the drive manufacturer prints on the label. 507127-B21 is the HPE option kit number used to order the drive as a sales item. 507284-001 is the HPE spare part number. This family also includes 11 assembly revisions, 15 OEM drive models, two generic part numbers 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 finished drive assembly.
EG0300FBDBR ships in several HPE option kits — which one do I need?
This drive ships under 507127-B21, 652564-B21 and AP875A. 652564-B21 is the Enterprise-line kit using the SC carrier and covers Gen8, Gen9 and Gen10 servers. 507127-B21 and AP875A cover earlier platforms; check the compatibility list on each kit's page and match it against your server model and generation before ordering, since the carrier and bay design differ between server generations even though the drive inside is the same.
What are the drive's core specifications?
EG0300FBDBR is a 300GB hard drive with a SAS (Serial Attached SCSI) interface, dual port, running at an external data transfer rate of 6 Gb/s. Rotational speed is 10,000 rpm. The form factor is 2.5-inch low profile SFF, with a height of 0.591" and a width of 2.75". It is configured as a hot-plug drive for server and storage use, and the hot-swap tray is included and attached.
Which servers accept this drive?
Supported platforms include the BL blade line (BL20p G4, BL25p G2, BL45p G2, BL460c and BL465c G1 through G7, BL480c, BL620c G7, BL680c G5/G7, BL685c G1 through G7, BL860c, BL870c), the DL rack line (DL120 G7, DL160 G6, DL165 G7, DL180 G6, DL320 G6, DL360 G4p through G7, DL365, DL370 G6, DL380 G4 through G7, DL385, DL580, DL585, DL785, DL980 G7, DL1000, DL170e/DL170h G6, DL160se G6), the ML tower line (ML350 G5/G6, ML370 G4/G5/G6, ML570 G3/G4), plus SL390s G7 and WS460c G6.
Does the drive come with a caddy?
Yes. The hot-swap tray is included and already attached to EG0300FBDBR, so the drive is ready to insert into a compatible 2.5-inch SFF hot-plug bay without transferring hardware from an existing drive. Because carrier designs differ across server generations, confirm the option kit listed for your platform matches the bays in your chassis.
