Product overview
P25960-B21 is an HPE mellanox ConnectX-6 dx dual port 100GbE QSFP56 PCIe network Adapter. The bracket matters: a card shipped with the wrong height will not close a 1U chassis. Tell us the server and we will supply the right bracket with it.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

What you get ordering this from us
Ordered by part number
The order is placed against P25960-B21, not against a description of it, so there is no room for a substitution you did not agree to.
Driver support confirmed
We check the adapter against your OS and hypervisor version, because the slot is never the constraint.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
- Is P25960-B21 genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will P25960-B21 work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- 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.
