HPE QR477A 300GB 6G SAS 15K 2.5″ HDD

HPE QR477A M6625 300GB 6G SAS 15K SFF EVA Hard Drive

HPE QR477A is the option kit for the M6625 300GB 6G SAS 15K rpm SFF (2.5 inch) dual port hard drive. It was designed for the HPE EVA M6625 disk enclosure, the 25-bay small form factor shelf used with the EVA P6000 family such as the P6300 and P6500.

EVA owners use QR477A drives in performance disk groups, where many small 15K spindles give quick response to busy applications. If a disk in an M6625 shelf has failed, this is the matching replacement: 300GB, 15,000 rpm, 6Gb/s dual port SAS, 2.5 inch, in the EVA carrier.

QR477A drives can be ordered from Euroland IT Store in New and Refurbished condition, subject to current stock.

HPE QR477A Technical Specifications

What Is The HPE QR477A?

QR477A is the order code. Its spare part, 665750-001, is described in HPE PartSurfer as being for use with the EVA M6625 disk enclosure. Resellers list EH0300FBQDD, EH0300FCBVC and MK3001GRRB as the drive models fitted, and 627114-002 and 652625-002 as assembly numbers.

Several of those model and assembly numbers also appear on ProLiant 300GB 15K drives. That is exactly why the option or spare number matters: it identifies the EVA build with the right carrier and firmware, rather than a server drive that shares the same bare disk.

Small Form Factor 15K Drives In An EVA

The M6625 packs 25 drives into 2U, which let EVA P6000 owners put a large number of 15K spindles behind the controllers in little rack space. More spindles mean more input and output operations per second, so a disk group of QR477A drives suits transactional databases, email and virtual server storage where response time matters more than capacity.

The EVA spreads data across every disk in a group, so one slow or failing drive can affect the whole group. Replacing a failed QR477A promptly, with the same size and speed, keeps performance even and lets the array return the group to full protection.

New HPE QR477A

New QR477A drives suit customers who need an unused part for a production EVA, or who want a sealed spare on site. The listing confirms the warranty offered with new stock.

Refurbished HPE QR477A

Refurbished QR477A units are a cost-effective way to support EVA P6000 systems that are past their original support term. Condition and warranty for refurbished drives are on the product page.

Compatibility

• HPE EVA M6625 SFF disk enclosure
• HPE EVA P6300 and P6500 storage systems using M6625 shelves

QR477A is not a ProLiant server drive and will not fit LFF M6612 shelves. Check the label on your current disk and your enclosure model before ordering.

How To Check You Need QR477A

1. Confirm the shelf is an M6625 with 25 SFF bays.
2. Read the failed drive label for QR477A or 665750-001.
3. Use HPE Command View EVA to confirm the disk group holds 300GB 15K drives.
4. Make sure the replacement goes into the same bay so the controllers can bring it into the group.

Keeping An EVA P6000 Healthy Until Migration

An EVA P6000 that still runs reliably can be worth keeping for a while, especially if the applications on it are due to be retired. The main risk is a slow build-up of failed disks. Check Command View EVA regularly, replace failed QR477A drives as soon as they are flagged, and keep the protection level of each disk group set so the array holds spare capacity for rebuilds.

Use the time to plan the move to newer storage. Spare drives for 6G EVA shelves are getting harder to find, so a spare or two on site gives you breathing room while the migration project runs.
