| Availability: | In Stock |
HPE 881781-B21 is the option kit for a 12TB large form factor SAS hard drive that ships in HPE’s low profile (LP) carrier. PartSurfer describes it as a 12TB SAS 12G Business Critical 7.2K LFF LP drive with helium construction and 512e sectors, from HPE’s multi vendor range.
This version is for HPE servers and enclosures built around the shorter LP tray, which HPE uses in many newer LFF platforms. If your system takes SmartCarrier trays instead, the matching option is 881779-B21. Specs in brief: 12TB, SAS 12Gb/s, 7,200 rpm, 3.5in, LP carrier, 512e.
The Euroland IT Store catalogue carries 881781-B21 in both New and Refurbished grades, subject to availability.

The -B21 code marks the HPE option kit. In this case the kit contains spare 882398-001, which HPE describes as a 12TB SAS 3.5in 7,200 rpm LP drive with helium and Digitally Signed firmware. So the option and spare describe one physical drive, and resellers list MB012000 model codes such as MB012000JWDFD and MB012000JYCJF under it.
HPE uses almost the same wording for 881779-B21. The only difference in the description is LP against SC, and that is exactly why the number matters. Mixing them up is the most common reason a replacement drive will not seat.
HPE QuickSpecs give the LP carrier a depth of about 156.6mm, against about 170mm for the SmartCarrier. The LP tray is a simpler, more compact design. The SC tray has an LED ring, locator and do not remove indicator on its face.
Because the trays differ in size and latch design, the bay in your server decides which you need. The HPE where-used list for spare 882398-001 includes DL380 Gen11 LFF and DL345 Gen11 LFF builds, plus the D8000 disk enclosure. HPE’s 10TB LP spare appears in ML350 Gen10 configurations, a reminder that some Gen10 towers also use LP trays.
New units are best when you populate a new server or enclosure, or where your security policy rules out previously used disks. See the product page for the packaging and warranty that apply.
Refurbished 881781-B21 drives cost less and make sense for replacing a failed LP drive or building a spares stock for several sites. Condition notes and warranty terms for refurbished stock are on the product page.
From HPE where-used data for spare 882398-001:
Other HPE servers with LP LFF SAS bays can also use it. Check the old drive label, your exact server model and the controller before ordering, as SC bays will not take this drive.
You can run 12TB LP drives next to smaller drives in the same chassis, as long as each logical drive is built from matching members. A typical layout keeps a pair of smaller drives for the operating system and a separate array of 12TB disks for data. That keeps rebuilds of the large array away from the boot volume.
Euroland IT Store supplies UK firms, school and council IT teams, resellers and repairers with HPE drives. Condition, warranty, stock and delivery options are on the product page.

HPE PartSurfer lists 881781-B21 with a low profile (LP) carrier, while the SmartCarrier version is 881779-B21.
HPE where-used data for its spare includes the DL380 Gen11 LFF, DL345 Gen11 LFF and the D8000 enclosure, so check that your server has LP 3.5in bays.
