FREQUENTLY ASKED QUESTIONS ABOUT EG0300FBLSE
What is the difference between EG0300FBLSE, 507127-B21 and 507284-001?
They identify the same physical 300GB 6G SAS 10K drive at different levels. EG0300FBLSE, this page, is an OEM model number — the manufacturer's designation printed on the drive label itself. 507127-B21 is the HPE option kit number, the orderable retail kit. 507284-001 is the HPE spare part number used for service replacement. The same drive also carries 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.
EG0300FBLSE 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 with an SC carrier, supporting Gen8, Gen9 and Gen10 servers, so choose it if your chassis takes SC-style carriers. 507127-B21 and AP875A cover the earlier platforms listed on this page. Match the kit to your server by checking the compatibility list on each kit's page against your exact model and generation before ordering.
