HP Ethernet 10Gb 2-port 530T Adapter 656596-B21 Low-Profile PCIe network card

SKU CH-QX0P-4VCJA

A low-profile PCIe 2.0 x8 network card with two 10Gb Ethernet RJ-45 ports for high-speed server connectivity

  • Dual 10GbE ports accelerate demanding server workloads
  • Low-profile PCIe 2.0 x8 fits compact server chassis
  • Two RJ-45 connectors simplify copper cabling
  • Part numbers 656596-B21, 657128-001, 656594-001 ensure correct ordering
  • Designed for HP server and workstation compatibility

HP 530T 10Gb dual-port NIC

This HP 530T adapter adds two 10Gb Ethernet RJ-45 ports through a low-profile PCIe 2.0 x8 slot. It is built for servers and workstations that need high-throughput wired connectivity. The card fits standard low-profile brackets for space-constrained chassis.

Suits 10GbE copper uplinks.

IT teams deploying 10GbE over Cat6a or Cat7 cabling will match both ports to existing RJ-45 infrastructure. Buyers who require SFP+ fibre transceivers or only a single 10Gb connection should select a different adapter. The dual-port layout also limits use in single-slot risers that cannot expose two external ports.

PCIe 2.0 x8 lane requirement decides fit

The adapter needs an x8 electrical link to deliver full 10Gb throughput on both ports simultaneously. Systems limited to x4 electrical slots will halve available bandwidth per port. Verify the motherboard or riser provides PCIe 2.0 x8 before purchase.

Questions about this item

Does the 656596-B21 include both low-profile and full-height brackets, or must I buy a bracket separately?

The card ships as a low-profile PCIe 2.0 x8 adapter with two 10Gb RJ-45 ports; a full-height bracket is not included and must be sourced separately if your chassis requires it.

Should I choose the 656596-B21, 657128-001 or 656594-001 part number for a standard two-port 10Gb RJ-45 server install?

All three numbers refer to the same 530T dual-port 10Gb RJ-45 adapter; 656596-B21 is the primary ordering code, while 657128-001 and 656594-001 are alternate manufacturing part numbers for the identical card.

What real-world throughput can I expect from each 10Gb port once the adapter is seated in a PCIe 2.0 x8 slot?

Each port is rated for 10Gb Ethernet; the PCIe 2.0 x8 interface provides up to 16 Gb/s of bus bandwidth, so the two ports combined can approach line rate under typical server workloads.
