HPE 872842-B21 300GB 12G 15K 2.5″ SAS HDD

HPE 872842-B21 300GB 12G 15K 2.5in SAS Standard Carrier HDD

HPE 872842-B21 is an option kit for a 300GB, 15,000 rpm hard drive with a dual-port 12Gb/s SAS interface. It is a 2.5in small form factor disk with digitally signed firmware, supplied in HPE’s standard (ST) carrier rather than the SmartCarrier used on most ProLiant Gen8 to Gen10 drives.

That carrier detail is what makes this part number special. Buyers are usually replacing a drive that already sits in a standard carrier, and they need the same tray so it fits and locks in the bay. The service spare for this option is 873031-001.

Euroland IT Store offers the 872842-B21 in New and Refurbished condition when stock is available.

HPE 872842-B21 Technical Specifications

What Is The HPE 872842-B21?

HPE builds its 300GB 15K 12G SAS disks into more than one finished product. The SmartCarrier version is 870753-B21. The standard carrier version is 872842-B21. Distributor records list the same bare disk models, EH000300JWCPK and EH000300JWHPL, for this drive, along with assembly numbers 867254-001 and 875217-001.

Because the disk can be the same while the carrier differs, the option number is the only reliable way to order the right complete drive. If your existing drive is in a standard carrier, a SmartCarrier replacement will not fit the bay, however closely the specifications match.

Standard Carrier Versus SmartCarrier

The SmartCarrier has a front bezel with activity, fault and “do not remove” indicators driven by the Smart Array controller. The standard carrier is a simpler frame designed for bays that are not built around SmartCarrier drives. The two have different shapes and latches, so they are not interchangeable.

When you look at your current drive, the difference is clear. A SmartCarrier has a ring-shaped light and a release button on the front. If yours does not, and the label shows 872842-B21 or 873031-001, this standard carrier version is what you need.

Dual-Port SAS In A Few Words

A dual-port SAS drive has two independent connections. In systems with two controllers or two expander paths, each port can be connected to a different path. If one path fails, the drive stays reachable through the other. This is a key reason SAS drives are used in enterprise storage where single points of failure must be avoided.

New HPE 872842-B21

New units suit systems that hold important data and buyers who want a drive with no previous use. Warranty terms for new stock are shown on the product page.

Refurbished HPE 872842-B21

Refurbished units are a cost-effective way to replace a failed standard carrier drive, especially in systems where these parts are now harder to find. The condition and warranty for refurbished stock are on the product page.

Compatibility

• HPE systems whose 2.5in bays take the HPE standard (ST) drive carrier
• Direct replacement for drives labelled 872842-B21 or 873031-001

This drive is not the right choice for SmartCarrier bays. For ProLiant Gen8, Gen9 and Gen10 servers with SmartCarrier bays, look at 870753-B21 instead. Before ordering, check the label and carrier style on your current drive, your server or enclosure model, and the controller.

Is This The Right Part?

1. Your current drive is in a carrier without the SmartCarrier light ring.
2. The label reads 872842-B21 or 873031-001.
3. Your array uses 300GB 15K drives.
4. The controller supports 12Gb/s SAS or will run the drive at a lower link rate.
5. You have confirmed the bay takes a 2.5in drive.

Mixing Carriers In One System

Some estates contain a mix of SmartCarrier and standard carrier systems. Keep spares for each type clearly labelled, because the drives inside can share a model code while the carriers will not swap. Recording the option and spare numbers for every bay in your asset list makes the next replacement quick and avoids returns.

872842-B21 Frequently Asked Questions

Will the 872842-B21 fit a SmartCarrier bay?

No, it uses HPE’s standard carrier, so for SmartCarrier bays in ProLiant Gen8 to Gen10 servers you need the SC version, 870753-B21.

Is a Refurbished 872842-B21 worth considering?

Yes, refurbished stock is a practical way to replace a standard carrier drive at lower cost, while New suits those who want an unused part.

What warranty is offered on the 872842-B21?

The warranty depends on the condition you choose, and it is shown on the product page.

Can the 872842-B21 be delivered within the UK?

Yes, we deliver across the UK, with free shipping to the UK mainland on orders over £100 + VAT.

Is 872842-B21 the same disk as 870753-B21?

They are listed with the same bare disk models, but 872842-B21 comes in a standard carrier and 870753-B21 in a SmartCarrier, so they are not interchangeable in the bay.
