HPE P26264-B21 10/25GbE 4-port SFP28 adapter

SKU CH-HV8M-FB0R8 MPN P26264-B21

Four-port SFP28 adapter with PCI Express 4.0 x16 host interface for 25GBase-X optical fibre connectivity in servers

  • Quad-port SFP28 adapter delivers 25 GbE throughput over optical fiber for long-distance server links
  • PCI Express 4.0 x16 host interface provides high-bandwidth, low-latency data transfer to the CPU
  • Four 25GBase-X ports enable dense multi-port connectivity for virtualised and converged workloads
  • Stand-up form factor fits standard server slots without consuming extra chassis space
  • Broadcom 57504 controller ensures reliable 10/25 GbE performance across all four ports

Quad-Port 10/25GbE Server Adapter

The HPE P26264-B21 is a four-port SFP28 network adapter built for servers that need high-density 10 GbE or 25 GbE connectivity. It uses a PCI Express 4.0 x16 host interface and the Broadcom BCM 57504 controller. The card targets virtualisation clusters, converged infrastructure and workloads that demand multiple optical links in a single stand-up bracket.

Sustained Multi-Port Throughput

With four active SFP28 ports sharing a PCIe 4.0 x16 lane, the adapter maintains line-rate 25GBase-X traffic across all ports without host-bus saturation. Optical fibre media eliminates the distance and electromagnetic limits of copper, so latency and packet loss stay consistent during prolonged storage replication, backup windows or east-west cluster traffic.

PCIe 4.0 x16 Host Interface Requirement

The card requires a free PCI Express 4.0 x16 slot to deliver its rated 25 GbE per port; a narrower or older-generation slot will reduce available bandwidth. Buyers whose servers only offer x8 or PCIe 3.0 slots cannot realise the full four-port 25 GbE capacity and should verify slot compatibility before purchase.

Questions about this item

How much power does the HPE BCM 57504 10/25GbE 4-port SFP28 adapter draw when running continuously?

The adapter uses a PCI Express 4.0 x16 host interface and four SFP28 ports; power draw depends on the installed optical modules and server airflow.

What must already be in the server for the P26264-B21 to operate?

An available PCI Express 4.0 x16 slot and compatible SFP28 optical transceivers with matching fiber patch cables are required.

Will the 25GBase-X quad-port card work in a system limited to PCI Express 3.0?

The card is built for PCI Express 4.0 x16; it will negotiate down to 3.0 speeds but maximum 25 GbE throughput per port may be reduced.
