HPE 785079-B21 1.2TB 12Gb SAS 10K HDD

HPE 785079-B21 1.2TB 12G SAS 10K SFF Dual-Port Enterprise Hard Drive

HPE 785079-B21 is an option kit for a 1.2TB Enterprise hard drive in the 2.5 inch small form factor. It spins at 10,000 rpm and has a dual-port SAS interface rated at 12Gb/s. Unlike most 12G drives, this kit was aimed at older HPE servers: HPE PartSurfer describes the matching spare as being for use with Gen7 or earlier models.

That makes the 785079-B21 a useful part for organisations still running G7-era HPE ProLiant or Integrity systems that need a large, fast SFF drive. It suits application data, databases, virtual machine storage on legacy hosts, and keeping long-running line-of-business systems healthy until they are migrated.

Euroland IT Store can supply the 785079-B21 in New or Refurbished condition, subject to current stock.

HPE 785079-B21 Technical Specifications

What Is The HPE 785079-B21?

785079-B21 is a 12G drive kit that HPE lists for its older G-series servers rather than for the SmartDrive bays of Gen8 onwards. Its spare part number is 785415-001, and parts databases list the assembly numbers 768788-004 and 785087-007 for it, plus drive models including EG1200JEHMC, EG1200JEMDA and EG1200JETKC.

The exact number matters a great deal here. HPE also sells 1.2TB 12G 10K drives in the SmartDrive Carrier for Gen8 to Gen10, such as 781518-B21. Those look similar on paper but are built for a different bay. Ordering 785079-B21 for a Gen9 server, or an SC drive for a G7 server, would leave you with a drive that does not fit.

Legacy Bays And 12G Drives

G7 and earlier HPE servers use Smart Array controllers that run at 6Gb/s or 3Gb/s. A 12G SAS drive is backwards compatible and negotiates down to whatever the controller supports. You will not get 12Gb/s link speed in these servers, but you still gain from the capacity of a 1.2TB drive and the Enterprise duty rating.

The dual-port design lets the drive work in multi-path setups, which some blade and storage configurations use. In a single-controller rack server only one port is active, which is normal.

New HPE 785079-B21

A New drive is the right call when a legacy system is business-critical and you want a spare with no running hours. Condition and warranty details for New units are on the product page.

Refurbished HPE 785079-B21

For older servers where budgets are tight, a Refurbished 785079-B21 is a sensible way to replace a failed disk and keep the system running until migration. You will find the condition and warranty of Refurbished 785079-B21 units on the product page.

Compatibility

Retail and parts listings name these systems for the 785079-B21:

• HPE ProLiant DL580 G7 and DL585 G7
• HPE ProLiant DL980 G7
• HPE ProLiant BL620c G7 and BL685c G7 server blades
• HPE Integrity BL860c i4 server blade

Other G7 and earlier servers with SFF bays may also accept it, but check carefully. Confirm your server model and controller, and compare the label on your existing drive before ordering. This kit is not intended for Gen8 or later SmartDrive bays.

Is This The Right Replacement?

1. Check your server is a G7 or earlier HPE model with SFF bays.
2. Read the old drive label for 785079-B21, 785415-001, 768788-004 or 785087-007.
3. Confirm 1.2TB, 10K and SAS.
4. Make sure you are not looking at a Gen8 to Gen10 SmartDrive Carrier drive.
5. Check the controller supports drives of this capacity, updating firmware first if needed.

Keeping Legacy Systems Running

Many businesses keep a G7 server going because it runs software that is hard to move. Holding a matched spare drive for that system is a low-cost insurance policy. Pair it with a regular backup and a migration plan, and the old hardware can keep working safely while you prepare its replacement.
