What is the network speed supported by the HP 405097-B21 adapter?

The adapter is specified as a 1Gb/s Gigabit Ethernet solution. This means each of its 2 x ports is designed for 1Gb/s operation within Gigabit Ethernet networks, aligning server connectivity with standard 1Gb/s switching and cabling infrastructures.

What type of interface does the HP 405097-B21 use in servers?

The HP 405097-B21 is described as a PCI Express mezzanine server network adapter card. This indicates that it is intended for server platforms that provide PCI Express mezzanine slots, rather than conventional PCI Express expansion slots found in other system types.

: "In what product category does the HP 405097-B21 belong?

This adapter is categorized as a Gigabit Ethernet PCI Express mezzanine adapter and more specifically as a dual-port 1Gb/s server network adapter. That classification confirms it is designed for server use cases where 1Gb/s Gigabit Ethernet and mezzanine card form factors are required.

What is the full model description for the HP 405097-B21?

The model is described as the HP 2 x Ports 1Gb/s Gigabit Ethernet PCI Express Mezzanine Server Network Adapter Card. This wording highlights the 2 x ports, 1Gb/s Gigabit Ethernet capability, PCI Express mezzanine interface, and its role as a server network adapter.

Product overview

The HP 405097-B21 is a server network adapter card designed for environments standardizing on Gigabit Ethernet. This model provides 2 x ports supporting 1Gb/s Gigabit Ethernet, enabling dual network connections from a single PCI Express mezzanine adapter. As a mezzanine server network adapter, it is suited to server platforms that use PCI Express mezzanine card slots for I/O expansion. The dual-port 1Gb/s configuration helps IT teams implement network segmentation, redundancy, or separate data and management paths while using a single adapter footprint. Belonging to the Gigabit Ethernet PCI Express mezzanine adapter category, this card aligns with infrastructure built around 1Gb/s Ethernet links. Organizations can standardize on this adapter where dual-port Gigabit connectivity and mezzanine card integration are required. The HP branding and clearly defined 2 x ports at 1Gb/s support consistent deployment in server-oriented network architectures.
