HPE 870753-S21 300GB 2.5in SAS Hard Drive

HPE 870753-S21 300GB SAS 12G 15K SFF SC Hard Drive

The HPE 870753-S21 is a 300GB, 2.5in small form factor hard drive with a 12Gb/s SAS interface and a spindle speed of 15,000 rpm. It is an Enterprise class disk in an HPE SmartCarrier, with digitally signed firmware, built for HPE ProLiant servers.

This is a drive for performance rather than bulk storage. It suits boot volumes, database logs and small, busy data sets in Gen8, Gen9 and Gen10 ProLiant servers. IT teams adding disks to an existing 15K array, or replacing a failed one, are the usual buyers.

Both New and Refurbished units are sold through Euroland IT Store, subject to what is in stock at the time.

HPE 870753-S21 Technical Specifications

What Is The HPE 870753-S21?

HPE sells this 300GB 15K drive as option kit 870753-B21. The 870753-S21 number shares the same base and is listed by distributors as the same 300GB, 15,000 rpm, 2.5in SAS drive. HPE uses suffixes such as -S21 for alternative packaging and channel versions of an option, so the -S21 and -B21 drives are the same specification. The service spare for this drive family is 870792-001.

Ordering against the right number matters because HPE produces 300GB 15K drives in several carriers and generations. A Gen9 or Gen10 server expects the SmartCarrier version. An older G7 tray or an MSA carrier will not seat correctly in those bays.

Digitally Signed Firmware Explained

The “DS” in HPE drive names stands for digitally signed firmware. The drive will only accept a firmware image that carries a valid HPE signature. This stops tampered or corrupted firmware from being loaded onto the disk, which matters to organisations with strict security rules for their servers.

For day-to-day use you will not notice any difference. Firmware updates still come through HPE’s normal service packs. The benefit is peace of mind that the code running on each disk is genuine.

New HPE 870753-S21

New units are a good choice for fresh builds or when you are expanding an array and want every disk to start with zero running hours. Warranty details for new stock are set out on the product page.

Refurbished HPE 870753-S21

Refurbished drives make sense when you are replacing a single failed disk in a server that is already a few years old. They cost less than new and use the same SmartCarrier. Please see the product page for the condition and warranty of refurbished units.

• Your controller firmware is reasonably current.

Using The SmartCarrier LEDs When You Swap A Drive

The SmartCarrier has a ring of lights around the drive button. A failed disk shows amber. The “do not remove” indicator warns you when pulling a drive would break the array. Wait until that warning is clear, press the release, slide the old drive out and push the new 870753-S21 in until it clicks. The controller will begin the rebuild on its own, and the activity ring will spin while it works.
