The HPE 872491-S21 is a 4TB SATA hard drive for 3.5in hot-plug bays, listed on our site under the S21 variant of HPE option 872491-B21. The drive runs at 6Gb/s and 7,200 RPM, carries digitally signed firmware and comes in an HPE SmartCarrier. HPE now sells the 872491-B21 option as a 4TB SATA 6G Business Critical 7.2K LFF SC multi-vendor drive; earlier listings called the same class Midline.

It suits anyone running ProLiant rack or tower servers with LFF SmartCarrier bays who needs affordable bulk storage. Typical roles are file shares, backup volumes and archive storage on Gen8, Gen9 and Gen10 systems.

You can buy the 872491-S21 from Euroland IT Store in New and Refurbished condition, subject to current stock.

HPE 872491-S21 Technical Specifications

What Is The HPE 872491-S21?

The base part here is HPE option 872491-B21. PartSurfer lists one spare under it, 872772-001, described as a 4TB SATA 6Gb/s, 3.5in, 7,200 RPM drive in a smart carrier with digitally signed firmware. Our listing uses the S21 ending; please check the label on your existing drive and contact us if you need to confirm how your number relates to the B21 option.

HPE fills this option with drives from several makers, and parts specialists list a number of HPE component numbers against it. They include 872293-002, 872295-002, 879481-001 and 846522-004. Any of these may appear on the drive body inside the carrier.

Hot-Plug Replacement With SmartCarrier

A SmartCarrier drive can be changed while the server is running. Before you touch a drive, look at the carrier LEDs. HPE carriers show when a drive is in use by an active array and should not be pulled. Remove only the failed drive, which usually shows an amber fault light.

Press the release button, lift the lever and slide the carrier out. Insert the new 872491-S21 firmly until the lever clicks shut. The controller will detect the disk and, if it belongs to a redundant array, begin rebuilding automatically.

New HPE 872491-S21

New units suit buyers expanding an array with fresh disks or meeting procurement rules for unused parts. Current condition notes and warranty for New 872491-S21 units are on the listing.

Refurbished HPE 872491-S21

Refurbished units are a cost-effective way to replace a failed 4TB SATA drive in an existing server. They are also a sensible choice for stocking spares. Read the condition and warranty notes on the listing.
