FREQUENTLY ASKED QUESTIONS ABOUT EG002400JWJNT
What is the difference between EG002400JWJNT, 881457-B21 and 881507-001?
All three identify the same physical drive. EG002400JWJNT, this page, is an OEM model number — the identifier printed on the drive label by the manufacturer that built it. 881457-B21 is the HPE option kit, the orderable part that includes the drive in its SC carrier. 881507-001 is the spare part number used for service replacement. The same family also includes one assembly revision and two further OEM drive models; an assembly part number identifies a specific build configuration of the finished unit. All are shown in the cross-reference block on this page.
Which kit do I need — 881457-B21 or P28352-B21?
881457-B21 is the Enterprise product line kit, supplied with the SC carrier, and is listed for Gen8, Gen9 and Gen10 servers. P28352-B21 is the Mission Critical product line kit, supplied with the BC carrier, and is listed for Gen10, Gen11 and Gen12 servers. Match the carrier type to your chassis drive cage and confirm your server model against the compatibility list on each kit's page before ordering.
What do 512e and Digitally Signed Firmware mean on this drive?
512e is Advanced Format: the drive uses 4K physical sectors internally but presents 512-byte logical sectors to the host, so it works with controllers and operating systems that expect 512-byte addressing. Digitally Signed Firmware means the firmware image carries a cryptographic signature the server verifies before loading, which blocks unsigned or altered firmware from being installed on the drive.
What interface and performance does EG002400JWJNT provide?
The drive uses a Serial Attached SCSI 3 interface with one SAS port rated at 12 Gb/s and a data transfer rate of 1.2 GB/s. The spindle turns at 10,000 RPM, which places it between 7.2K nearline drives and 15K performance drives. Capacity is 2.4 TB in a 2.5-inch small form factor housing. The drive is hot-swappable and installs in a 2.5-inch SFF compatible bay.
Which servers accept this drive?
It is listed for ProLiant DL and ML Gen8, Gen9 and Gen10 rack and tower servers, including DL360, DL380, DL560, DL580, ML350 and ML110 lines, plus DL325 Gen10 Plus v1 and DL385 Gen10 Plus v1. BladeSystem BL420c, BL460c, BL465c, BL660c and WS460c models are covered, along with Apollo SL and XL nodes and Synergy 480 and 660 compute modules. The bay must be 2.5-inch SFF with an SC carrier.
