Sieťový adaptér HP Enterprise HPE G4 4-Port 10/25G SFP28 E810 (P10582-001)

The HPE G4 4-port 10/25G SFP28 E810 network adapter is a server-class Ethernet card designed to provide high-throughput, low-latency connectivity for rack servers in data center and virtualization environments. With four SFP28 ports that support both 10G and 25G link speeds, the adapter enables flexible network configurations and increased uplink capacity. It is compatible with standard SFP28 optical and copper transceivers and supports common server networking features used to consolidate network interfaces and optimize traffic handling.

Advantages

This network adapter offers four independent SFP28 ports that allow deployment of mixed 10G and 25G connections, helping to scale network bandwidth without replacing existing cabling infrastructure where compatible transceivers are used. The design focuses on reduced latency and high throughput to meet demands of virtualized workloads, storage traffic, and east-west server communication. Support for standard SFP28 modules ensures interoperability with a wide range of optics and DAC cables. The adapter also provides a compact footprint suitable for modern rack-mounted server I/O architectures.

Suitable for

• Server uplinks to top-of-rack switches in data centers
• Virtualized environments requiring high network throughput
• Consolidating multiple NICs to free PCIe slots and simplify cabling
• High-performance storage networks and distributed applications

Key specifications

• Port count: 4 SFP28 ports supporting 10G and 25G link speeds
• Interface type: SFP28 module slots compatible with optical and copper transceivers
• Form factor: Low-profile server adapter suitable for rack servers
• Performance focus: High throughput and low latency for data center workloads
• Use case: Designed for uplinks, virtualization, and storage networking

How to use

Install the adapter into an available PCIe slot in a supported rack server following the server manufacturer's installation procedures. Insert compatible SFP28 transceivers or direct-attach copper cables into the module slots according to the desired link speed (10G or 25G). Configure network settings and link aggregation as required by the operating system or hypervisor, and verify link status and speed through the server's management tools. Ensure appropriate driver and firmware versions are installed to enable full functionality and performance.

Recommendations

Use certified SFP28 transceivers or vendor-recommended direct-attach cables to ensure reliable link negotiation and performance. Keep adapter firmware and drivers up to date to maintain compatibility with server OS and switch platforms. For mixed-speed environments, plan port assignments and link aggregation policies to balance load and preserve low latency for latency-sensitive workloads.
