HPE P08443-B21 10/25Gb SFP28 Network Adapter

HPE P08443-B21 Intel E810-XXVDA2 Ethernet 10/25Gb 2-Port SFP28 Adapter

The HPE P08443-B21 Intel E810-XXVDA2 Ethernet 10/25Gb 2-Port SFP28 Adapter provides high-speed network connectivity for compatible HPE ProLiant servers. Featuring two SFP28 Ethernet ports and an Intel E810 controller, it supports 10GbE and 25GbE connections for enterprise networking, server virtualisation and data-intensive applications.

Designed as a stand-up PCI Express adapter, P08443-B21 can be installed in a supported server expansion slot. Its PCIe 4.0 x8 interface and dual-port configuration make it suitable for organisations upgrading network bandwidth or replacing an existing adapter.

The adapter uses SFP28 interfaces rather than RJ-45 copper Ethernet ports. Buyers should therefore confirm the required transceivers, direct-attach cables and switch compatibility before ordering.

HPE P08443-B21 Technical Specifications

Bandwidth note: Each SFP28 port supports up to 25Gbps in one direction. The theoretical combined one-way port capacity is 50Gbps when both ports operate at 25GbE. Actual performance depends on the server, network equipment and configuration.

Key Features of the HPE Intel E810-XXVDA2 Adapter

• Dual-port connectivity: Provides two high-speed Ethernet connections for compatible server networks.
• 10/25GbE operation: Supports different network bandwidth requirements using qualified connections.
• PCIe 4.0 x8 interface: Provides a high-bandwidth connection between the network adapter and server.
• Intel E810 controller: Uses Intel networking technology designed for enterprise Ethernet workloads.
• SFP28 flexibility: Supports qualified optical transceivers and direct-attach cabling.
• Network boot capabilities: Includes documented PXE support, subject to the server’s firmware configuration.

Compatible HPE ProLiant Servers

HPE documents P08443-B21 for selected ProLiant Gen10 Plus, Gen11 and Gen12 server platforms.

Examples of server families with documented support include selected configurations of:

• HPE ProLiant DL360 Gen10 Plus
• HPE ProLiant DL320 Gen11
• HPE ProLiant DL560 Gen10
• Other qualified HPE ProLiant and HPE compute platforms listed in the relevant QuickSpecs

Compatibility is configuration-specific. For example, HPE’s DL360 Gen10 Plus documentation includes an installation restriction for P08443-B21 concerning factory diagnostics requirements.

Before purchasing, verify the exact server model, PCIe riser, firmware, operating system and supported network transceivers.

10GbE and 25GbE SFP28 Connectivity

The HPE P08443-B21 provides two SFP28 ports for high-speed Ethernet networking. These interfaces can be used with supported optical transceivers or direct-attach copper cables.

For 25GbE operation, both the adapter and connected switch must support the selected connection type and speed. The appropriate cabling or optical components must also be used.

Organisations operating existing 10GbE networks can evaluate the adapter for supported 10GbE connections while planning a transition to 25GbE infrastructure.

Important: SFP28 is a different physical interface from 10GBASE-T RJ-45. The adapter does not provide built-in RJ-45 Ethernet sockets, and optical transceivers should not be assumed to be included.

Applications in Enterprise Server Networks

The dual-port design can be useful for servers handling significant network traffic, including virtualisation hosts, application servers and storage-related Ethernet workloads.

Depending on the operating system and switching infrastructure, administrators may use separate ports for different network segments or configure supported teaming arrangements.

Network redundancy requires suitable switch connections and software configuration. Installing a dual-port adapter alone does not guarantee automatic failover.

Stand-Up PCIe Adapter vs OCP 3.0 Version

HPE offers related Intel E810 adapters in different physical formats. Selecting the correct version is important because the installation interfaces are not interchangeable.

• P08443-B21: Intel E810-XXVDA2 dual-port 10/25GbE SFP28 stand-up PCIe adapter.
• P10106-B21: Intel E810-XXVDA2 dual-port 10/25GbE SFP28 OCP 3.0 adapter.
• P08458-B21: Intel E810-XXVDA4 four-port 10/25GbE SFP28 stand-up adapter.

Choose P08443-B21 when the server configuration calls for the stand-up PCIe version. The OCP 3.0 model requires a compatible OCP network adapter slot.

Installation and Replacement Considerations

Before installing the HPE P08443-B21, confirm that the server has a supported PCIe expansion slot and the required cooling configuration.

Follow the maintenance procedure for the relevant ProLiant server. After installation, verify that the Intel E810 adapter is recognised and that the appropriate network driver and firmware are installed.

Connect the adapter using qualified transceivers or cables, then check both port links and their negotiated speeds.

For an existing server replacement, retain a record of the previous network configuration, including VLAN settings, IP assignments and any teaming arrangements.

New and Refurbished HPE P08443-B21

New HPE P08443-B21

A New or unused HPE Intel E810-XXVDA2 adapter may be suitable for server upgrades, infrastructure expansion and planned maintenance. Confirm stock availability, packaging, included brackets and warranty terms before ordering.

Refurbished HPE P08443-B21

A Refurbished P08443-B21 may provide a cost-effective alternative for businesses maintaining compatible ProLiant servers. Buyers should request confirmation of hardware inspection, controller detection and functional testing of both SFP28 ports.

For either condition, confirm whether optical transceivers, DAC cables and mounting accessories are supplied separately. Warranty coverage and UK delivery options should also be checked before purchase.
