HPE 881779-B21 12TB 7.2k SAS 12Gbps HDD

HPE 881779-B21 12TB SAS 12G 7.2K LFF SmartCarrier Hard Drive

HPE 881779-B21 is the option kit for a 12TB, 3.5in large form factor hard drive with a 12Gb/s SAS interface and a 7,200 rpm spindle, fitted in an HPE SmartCarrier. HPE classes it as a Business Critical (Midline) drive, sealed with helium and formatted 512e, with HPE Digitally Signed Firmware.

It is aimed at HPE ProLiant servers with SC LFF bays, mainly the Gen10 family, where you want a lot of capacity in each slot. Backup repositories, archive shares, CCTV storage and large file servers are the usual jobs for a drive like this.

Find the 881779-B21 at Euroland IT Store, offered New or Refurbished according to current stock.

HPE 881779-B21 Technical Specifications

What Is The HPE 881779-B21?

PartSurfer lists 881779-B21 as an HPE 12TB SAS 12G Business Critical 7.2K LFF SC 1-year warranty helium 512e multi vendor HDD. HPE QuickSpecs use the same wording. The -B21 ending marks it as the option kit, the version you order when adding drives to a server.

The service spare that sits behind this option is 882397-001, which HPE labels SPS-DRV HDD 12TB 7.2K LFF SAS SC HE DS. The 12TB low profile version is a separate option, 881781-B21, so the SC in the description matters. Pick the wrong one and the tray will not latch in your bay.

SAS 12G or SATA 6G for a 12TB Disk?

HPE sells 12TB Business Critical drives in both SAS and SATA. Both spin at 7,200 rpm, so raw throughput on one disk is similar. The differences show up in how the drive talks to the controller.

SAS links run at 12Gb/s and are full duplex, so the drive can send and receive at the same time. SAS also handles error recovery and command queuing in a way that suits multi disk RAID sets and SAS expanders in busy LFF chassis. SATA drives cost less per terabyte and are fine for lighter, single user backup targets. If your existing array already uses SAS, stay with SAS, because a Smart Array logical drive cannot mix the two.

New HPE 881779-B21

New stock is right for a fresh Gen10 build or for adding new capacity where unused drives are required by policy. Check the product page for what comes with a new unit and the warranty on offer.

Refurbished HPE 881779-B21

Refurbished drives give the same 12TB SC build at a lower price. They fit well where you are repairing a degraded array or keeping spare stock for a fleet of servers. The condition and warranty notes for refurbished units sit on the product page.

Compatibility with HPE Servers

Pre-Order Checks

• Does the failed drive say 881779-B21, 882397-001 or a MB012000 model?
• Is the carrier an SC tray with a lever and LED ring?
• Is the array built from SAS drives?
• Is the logical drive made of 12TB members, or smaller ones?
• Has the controller been updated with a recent Service Pack for ProLiant?

Growing an Array with 12TB Drives

Smart Array controllers can expand a logical drive when you add disks of the same type. Adding 12TB members to an array of smaller disks wastes the extra space, since each member is treated as the smallest in the set. For a real capacity jump, build a new array from 12TB drives and migrate, or replace members one at a time and expand once all have been swapped.
