Product overview
Part number 861746-B21 identifies this HPE 6TB 7200RPM SAS 3.5-Inch hard Drive. Carriers and caddies are chassis-specific and are almost never included with a bare drive; this is 3.5-Inch. Give us the server model and we will quote the carrier alongside it instead of letting it hold up the swap.
Priced per unit, with tiered pricing at quantity — send the number you need and we will come back with the banded price.

What you get ordering this from us
Ordered by part number
Quoted and supplied against 861746-B21 specifically, so what arrives is what your build sheet asks for.
Firmware family matched
A mechanically identical drive with the wrong firmware is rejected by the controller; we check the family, not just the capacity.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
- Is 861746-B21 genuine and is the warranty intact?
- Yes. It ships new in HPE packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will 861746-B21 work in my server?
- Send the server model or the shelf it is going into. Vendor-keyed firmware is the usual reason an identical-looking drive is rejected, so we check that alongside interface and form factor.
- Do you accept purchase orders and quote at volume?
- Yes — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
