HPE 857642-002 10TB 7.2K 3.5″ SAS HDD

HPE 857642-002 10TB SAS 12G 7.2K 3.5in 512e Helium Drive

HPE 857642-002 is a drive level part number for a 10TB, 3.5in hard disk with a 12Gb/s SAS interface and a 7,200 rpm spindle. HPE PartSurfer describes it as a 10TB 7.2K SAS 12G 3.5in 512e helium drive built by HGST, one of the disk makers HPE sources from for its multi vendor 10TB range.

Most people search for this number because it is printed on a failed or spare disk taken out of an HPE ProLiant server. It is a practical reference for anyone matching a replacement to an existing 10TB SAS array. Key facts: 10TB, SAS 12G, 7.2K rpm, 3.5in, 512e, helium sealed.

You can pick up 857642-002 from Euroland IT Store as a New or Refurbished drive, depending on what is in stock on the day.

HPE 857642-002 Technical Specifications

What Is The HPE 857642-002?

HPE uses several layers of numbers for one drive. There is the option kit you buy for a new server, the spare part that service teams order, the model code on the disk label and, for multi vendor drives, a drive level number that identifies the exact mechanism. 857642-002 is one of those drive level numbers. The PartSurfer entry is marked as preliminary data and gives no where-used list, so we keep claims about it narrow.

Newegg lists 857642-002 together with model MB010000JWAYK. A UK and US reseller also lists 857644-B21 and 857644-S21 as equivalents, so this disk is commonly sold as a replacement for the 10TB Business Critical LFF option. If your service contract needs one specific number, ask us to check the label before we send it.

Multi Vendor Drives in One Array

HPE buys 10TB mechanisms from more than one manufacturer and gives them HPE firmware, so the controller treats them as the same product. That is why your array might contain a mix of labels with different drive level numbers yet identical capacity and speed. Mixing them within one logical drive is normal for HPE builds.

The firmware is the important part. HPE drives check in with Smart Array and HPE HBA controllers, report health through iLO, and receive updates from HPE. A plain retail 10TB disk lacks that firmware and can show as an unsupported or third party drive.

New HPE 857642-002

A new 857642-002 suits customers who want a sealed, unused drive for production storage. The packaging may vary, and the warranty on new stock is given on the product page.

Refurbished HPE 857642-002

A refurbished unit is a sensible pick when you are repairing an out of warranty server or building up a pool of tested spares. The condition grade and the warranty that apply are listed on the product page, so take a quick look before ordering.

Which Servers Is It Compatible With?

HPE does not publish a where-used list for 857642-002 itself. When sold as a replacement for the 10TB LFF options, it is used in:

• HPE ProLiant Gen9 and Gen10 servers with 3.5in SAS bays
• HPE ProLiant DL380 Gen10 and DL360 Gen10 LFF models
• HPE D3600 and D3610 LFF disk enclosures

Check your server model, your controller and the label on your current drive. Also check whether your bays use SmartCarrier or low profile trays, and tell us which one you need.

Right Replacement Checklist

• Look for 857642-002 or MB010000JWAYK on the failed disk.
• If the label shows only an option or spare number, send it to us and we will cross check.
• Note the tray type and whether it must move across.
• Confirm the logical drive is SAS and 10TB or smaller per member.
• Back up any data that is not already protected before the swap.

Replace the Drive, Keep the Server

A single failed disk is rarely a reason to retire a Gen9 or Gen10 server. Those platforms still offer plenty of processing headroom for file, backup and archive roles. Swapping one 10TB drive costs a fraction of a new build and avoids a data migration project. Fit the replacement, let the array rebuild, then plan any wider refresh on your own timetable.
