HPE Q2R42A MSA 12TB 7.2k SAS 12Gbps 512e HDD

HPE Q2R42A MSA 12TB 12G SAS 7.2K LFF Midline 512e Hard Drive

HPE Q2R42A is the option kit for the MSA 12TB 12G SAS 7.2K LFF (3.5 inch) Midline 512e hard drive. It is listed in the HPE MSA 2050 QuickSpecs and was the 12TB building block for capacity tiers on that generation of Modular Smart Array.

Businesses use the Q2R42A where they need a lot of space per bay: backup targets, archive shares, media libraries and long term records. The drive runs at 7,200 rpm over a 12Gb/s SAS link, uses 512e sectors and arrives in the hot-plug MSA LFF carrier.

New and Refurbished Q2R42A drives are available from Euroland IT Store, subject to current stock.

HPE Q2R42A Technical Specifications

What Is The HPE Q2R42A?

Q2R42A is the code you order from HPE or a reseller. The drive inside carries the spare number P00442-001, which is what HPE support uses for replacement parts. Both point to the same MSA 12TB Midline 512e disk, so either number on your label leads you here.

Ordering by the MSA number rather than by size is important. HPE says MSA drives are only for MSA storage systems, and a 12TB ProLiant drive has a different carrier, so it will not slot into an MSA bay or be accepted by the controllers.

Building A Capacity Tier With 12TB Drives

HPE also offered this capacity as a 72TB six-drive bundle, R0P92A, in the same QuickSpecs. That tells you how the drive was meant to be used: in groups, forming a large Midline pool behind a smaller set of faster Enterprise disks or SSDs. On the MSA 2050 you can mix SSD, Enterprise SAS and Midline SAS in one enclosure, each in its own disk group.

HPE notes that Midline drives should not be used in heavy or intense I/O environments. Keep the Q2R42A for sequential and capacity work, and place transactional data on 10K, 15K or flash tiers.

Encryption: Do Not Mix With SED Drives

The Q2R42A is a standard, non-encrypted drive. The MSA 2050 QuickSpecs explain that to use array encryption every drive must be self-encrypting, and that encrypted and non-encrypted drives cannot be mixed in one array. If your MSA uses SED drives, this is not the right replacement.

New HPE Q2R42A

A new Q2R42A fits projects that add several drives at once, where a matched batch of unused disks is preferred. The listing states the warranty supplied with new drives.

Refurbished HPE Q2R42A

Choose a refurbished Q2R42A to replace a failed member in an MSA that is already in service, or to keep a spare in the comms room. The refurbished Q2R42A listing shows its grade and the cover that comes with it.

Compatibility

• HPE MSA 2050 and MSA 2052 (HPE QuickSpecs)
• HPE MSA 1050 LFF configurations (reseller listing)
• HPE MSA 2040 LFF systems (reseller listing)

HPE states that earlier MSA drives are not compatible with MSA Gen6 systems, so the Q2R42A is not for the MSA 1060, 2060 or 2062. It is also not a ProLiant server drive. Check the label on your existing drive and your enclosure model before ordering.

Frequently Asked Questions

Can I fit the Q2R42A in an MSA 2060?

No, HPE states that prior-generation MSA drives are not compatible with Gen6 arrays, so the Q2R42A suits the MSA 2050 range and earlier LFF systems.

What is the spare part number for Q2R42A?

The spare part number is P00442-001, which HPE service uses for this MSA 12TB 12G SAS 7.2K LFF Midline drive.

Is it worth buying the Q2R42A Refurbished?

Refurbished is a sensible route for replacing a failed member in a working array, while New suits matched expansions; stock of each varies.

What warranty is included with the Q2R42A?

Warranty depends on whether you choose New or Refurbished, and the terms are shown on the product page.
