HP Ethernet 10Gb 2P 530T Adapter 656596-B21

Dual-port 10GBASE-T adapter

The HP Ethernet 10Gb 2-port 530T Adapter provides two 10GBASE-T ports in a PCIe 2.0 form factor for HP ProLiant Gen8 servers. It uses the Broadcom BCM57810S controller to deliver full line-rate throughput across both ports. The card is designed for virtualisation and cloud workloads that need reliable 10 Gb Ethernet over copper cabling. It fits standard low-profile server slots and requires no proprietary transceivers.

Low power draw and thermal profile

The adapter maintains low power consumption while sustaining full line-rate traffic on both ports. Typical server airflow is sufficient to keep the BCM57810S controller within operating limits without additional cooling. Acoustic output remains negligible because the card has no onboard fan and relies on the chassis fans. CAT 6A UTP links up to 100 metres without signal degradation.

Broadcom controller enables advanced offloads

The BCM57810S handles TCP/IP checksum, segmentation and receive-side scaling in hardware, reducing host CPU utilisation during heavy network loads. Driver support covers major hypervisors and operating systems used in Gen8 deployments. No separate licence or management utility is required beyond the standard OS networking stack. The adapter ships ready for immediate installation in compatible servers.
