HP 436M8AA 25 Gigabit Ethernet network card 2 Port SFP28 Low Profile

SKU CH-2J2Y-41J2Y MPN 436M8AA

Dual-port 25 Gigabit Ethernet adapter with SFP28 connectors and low-profile bracket

  • Dual 25 GbE ports for high-throughput networking
  • Low-profile bracket fits compact server chassis
  • SFP28 cages support direct-attach or optical modules
  • Plug-in card design enables quick PCIe installation
  • Coaxial interface option listed for specialised links

Dual-port 25 GbE server adapter

The HP 436M8AA is a dual-port 25 Gigabit Ethernet network interface card built for servers and workstations that need higher throughput than standard 10 GbE links. It uses an SFP28 interface for fibre or direct-attach copper connections and ships with a low-profile bracket for dense chassis.

Upgrade path from 10 GbE infrastructure

This card replaces single-port or 10 Gigabit adapters when aggregate bandwidth above 20 Gb/s is required for storage replication, virtualisation clusters or high-performance computing nodes. The jump is worth it when switch uplinks and cabling already support 25 GbE speeds and latency-sensitive workloads saturate existing 10 GbE paths.

SFP28 reach and transceiver limits

Practical link distance depends entirely on the SFP28 transceivers chosen; short-range optics typically cover tens of metres while long-range modules extend to kilometres. The card itself does not dictate reach, so buyers must match transceivers to their cable plant and cannot exceed the electrical or optical limits of the installed modules.

Questions about this item

Does the low-profile bracket fit a standard half-height PCIe slot?

Yes, the card uses a low-profile bracket designed for half-height PCIe slots and includes two SFP28 ports.

Is the driver included on the card or must it be downloaded before installation?

The card is a plug-in PCIe device; the operating system loads the driver automatically or you download the latest driver from the HP support site for model 436M8AA.

When will the SFP28 transceivers need replacement?

SFP28 transceivers are hot-swappable modules; replace them only if a link fails or when you upgrade to a different 25 Gigabit Ethernet standard.
