## Summary description

HP Enterprise P51178-B21 is an internal wired Ethernet network card with PCI Express host interface and up to 1000 Mbit/s maximum data transfer rate. Designed for installation in servers or workstations to provide gigabit LAN connectivity, it supports standard Ethernet networking for data transfer, remote management and networked storage access.

## Long description

HP Enterprise P51178-B21 is an internal wired Ethernet network card designed for installation in servers and workstations with a PCI Express slot. The adapter provides gigabit LAN connectivity with up to 1000 Mbit/s maximum data transfer rate, enabling standard Ethernet networking for file transfer, remote management and networked storage access. The card is intended to deliver reliable wired networking in environments that require predictable throughput and integration with existing Ethernet infrastructure.
Advantages
The adapter offers improved performance for bandwidth- and latency-sensitive applications by reducing CPU utilization through support for I/O offloads such as remote direct memory access (RDMA) and tunneling. Its design emphasizes reliability and security: firmware update authentication and digitally signed firmware verification via a root-of-trust architecture help reduce the risk of rogue firmware installation and maintain a trusted networking stack.
Suitable for
Enterprise servers requiring gigabit LAN connectivity
Workstations that need a stable wired network connection for data transfer and remote management
Networked storage access and SAN connectivity over Ethernet
Latency-sensitive applications and virtualization hosts that benefit from I/O offloads
Key specifications
Interface: PCI Express (internal card)
Data transfer rate: up to 1000 Mbit/s (Gigabit Ethernet)
Port type: wired Ethernet port(s) compatible with standard RJ-45 copper connections
Offload features: support for RDMA and tunneling to reduce CPU load
Security features: signed firmware verification and root-of-trust based authentication for firmware updates
Intended use: server and workstation internal installation for wired LAN connectivity
How to use
Install the network card into an available PCI Express slot on a powered-down server or workstation following the system manufacturer's service instructions. Secure the card in the chassis, connect a compatible Ethernet cable to the port, and boot the system. Install or enable the appropriate network drivers for the operating system in use and configure network settings (IP addressing, VLANs, link speed/duplex) according to network policies. Verify link status and throughput after configuration.
Usage recommendations
Use shielded or quality-rated Ethernet cables and compatible switch ports to achieve stable gigabit performance. Keep firmware and drivers up to date with signed releases from the vendor to maintain security. When deploying in latency-sensitive or high-throughput environments, enable supported I/O offloads and validate settings in a test environment before production roll-out.
