HPE 870763-B21 600GB 15kRPM SAS-12G HDD

HPE 870763-B21 600GB 15K SAS 12G SFF 512e Hard Drive

HPE 870763-B21 is the option kit number for a 600GB Enterprise hard drive running at 15,000 rpm over 12Gb/s SAS. It is a 2.5in small form factor disk in an HPE SmartCarrier, with digitally signed firmware and the 512e sector format.

The drive is built for HPE ProLiant servers that need quick random access, such as database, email and virtualisation hosts. It is usually ordered to expand or repair an array that already uses 512e 15K drives, or to build a new array on a current-generation server.

You can buy the 870763-B21 New or Refurbished from Euroland IT Store, based on stock available when you order.

HPE 870763-B21 Technical Specifications

What Is The HPE 870763-B21?

HPE’s full description for this option is a 600GB SAS 12G Enterprise 15K SFF SC 512e drive with digitally signed firmware. The spare number is 870797-001, and the disk inside is listed under models such as EH000600JWCPF and EH000600JWHPH, with assembly number 868775-003.

The detail that sets 870763-B21 apart is the sector format. HPE sells a near-identical 600GB 15K SFF drive with 512n sectors as 870757-B21. If you order by capacity and speed alone, you may end up with the wrong format for your array, which is why the exact part number is worth checking.

What 512e Means In Practice

Inside a 512e drive, data is written to the platters in 4K physical sectors. The drive firmware then presents those sectors to the server as 512-byte logical blocks. The “e” stands for emulation.

The larger physical sector allows more efficient error correction on the platter. The emulation keeps the drive compatible with software that still expects 512-byte blocks. For best performance, partitions should start on a 4K boundary. Modern versions of Windows Server, Linux and VMware ESXi do this automatically. Very old operating systems may not, so check before you use 512e drives with legacy software.

New HPE 870763-B21

New drives are best for new arrays and for servers that run critical services. The product page tells you which warranty applies to new stock.

Refurbished HPE 870763-B21

Refurbished drives cost less and suit replacements in servers that are already in service. They are also a sensible way to hold a spare on site. Please check the condition and warranty on the product page.

Compatible Servers

• HPE ProLiant Gen10 servers with SFF SmartCarrier bays, including the DL560 Gen10, DL580 Gen10 and ML110 Gen10
• HPE ProLiant Gen9 servers with SFF SmartCarrier bays and current controller firmware

Check the label on your current drive, your server model and the controller before ordering. Make sure your operating system and controller support 512e drives, and update the Smart Array firmware if the server has not been updated for some time.

Right Replacement Checklist

1. Check the carrier label for 870763-B21 or 870797-001.
2. Confirm the other drives in the array are also 512e.
3. Make sure the bay is an SFF SmartCarrier slot.
4. Confirm the server is Gen9 or Gen10.
5. Check the operating system version supports 512e.

Planning A New 15K Array On Gen10

If you are building a new array, decide on the sector format first and stick with it. A set of 600GB 512e drives in RAID 10 gives good random performance with simple rebuilds. RAID 5 gives more usable space but slower writes and longer rebuilds. Leave one bay free, or keep one drive on the shelf, so a failed disk can be replaced the same day.
