HPE P11785-001 MSA 14TB SAS 12G 7.2K LFF 512e Spare Drive

HPE P11785-001 is the spare part number for the MSA 14TB SAS 12G 7.2K LFF Midline 512e hard drive, sold as option kit R0Q21A. It is a 3.5 inch, 7,200 rpm, dual port SAS disk in the HPE MSA LFF carrier, and it was the largest single LFF hard drive in the HPE MSA 2050 option list.

This spare is the one to choose when a 14TB disk fails in an MSA 2050 or 2052 shelf, or when you need to bring a degraded capacity tier back to full strength. Specs at a glance: 14TB, SAS 12Gb/s, 7.2K rpm, LFF, 512e, helium filled according to reseller data.

Find the P11785-001 at Euroland IT Store in New and Refurbished condition, subject to current stock.

HPE P11785-001 Technical Specifications

What Is The HPE P11785-001?

The R0Q21A option was added to the HPE MSA 2050 QuickSpecs as the MSA 14TB 12G SAS 7.2K LFF Midline 512e drive. P11785-001 is its spare number, and resellers list P12341-003 as the assembly number, with drive models such as ST14000NM002G, ST14000NM0048 and WUH721414AL5204 used inside it.

For a buyer, the spare number is the most reliable match. It appears on the drive label, it is what HPE quotes for replacements and it marks the drive as an MSA part rather than a ProLiant 14TB disk, which uses a different carrier and is not supported in MSA enclosures.

Gen5 MSA Drive, Not Gen6

There is some confusion online about where R0Q21A fits, because many later MSA option codes also begin with R0Q. The HPE MSA 2050 QuickSpecs list R0Q21A, while the MSA 2060 QuickSpecs do not, and HPE states that prior-generation MSA drives are not compatible with MSA Gen6 systems. So the P11785-001 belongs in an MSA 1050, 2050 or 2052 class array, not an MSA 1060, 2060 or 2062.

Midline Capacity And Rebuild Planning

A 14TB Midline drive gives a lot of space per bay, which lowers the number of enclosures you need. The trade-off is rebuild time. Reconstructing a 14TB member can run for many hours, so dual parity protection and a global spare are good habits. HPE also notes that Midline drives are not intended for heavy, intense I/O.

New HPE P11785-001

New P11785-001 drives work well for adding a fresh 14TB disk group or keeping a sealed spare on site. See the product page for the cover offered with new drives.

Refurbished HPE P11785-001

A refurbished P11785-001 is a lower-cost way to restore a failed member in an MSA that still has years of useful life. The product page sets out the condition and warranty of refurbished stock.

Compatibility

• HPE MSA 2050 and MSA 2052 (R0Q21A appears in HPE QuickSpecs)
