What type of network adapter is the HPE 665246-B21?

The HPE 665246-B21 is the HPE Ethernet 10Gb 2-port 560M Adapter, categorized as a PCI Express 2.0 x8 dual-port Ethernet adapter. It is also identified as a 10 GbE mezzanine adapter, designed for enterprise environments that require 10 Gigabit Ethernet connectivity on a mezzanine form factor.

How many Ethernet ports does the HPE 560M adapter provide?

The HPE Ethernet 10Gb 2-port 560M Adapter provides two Ethernet ports. It is explicitly described as a dual-port Ethernet adapter, enabling designs that use multiple network paths on a single card, such as separating traffic types or implementing basic redundancy at the adapter level.

What is the bus interface for the HPE Ethernet 10Gb 2-port 560M Adapter?

The adapter is specified as a PCI Express 2.0 x8 dual-port Ethernet adapter. This means it connects to server systems through a PCIe 2.0 x8 interface while delivering dual 10Gb Ethernet ports, aligning with the bandwidth and slot format commonly available in many enterprise-class servers.

Is the 665246-B21 suitable for 10 Gigabit Ethernet deployments?

Yes, the 665246-B21 is explicitly described as an Ethernet 10Gb 2-port 560M Adapter and is categorized as a 10 GbE mezzanine adapter. This makes it suitable for deployments where 10 Gigabit Ethernet connectivity is required at the server level, particularly in enterprise and data center environments.

What kind of form factor does this adapter use?

The adapter is classified as a 10 GbE mezzanine adapter, indicating it is designed for mezzanine card slots rather than standard full-height or low-profile PCIe slots. This allows it to integrate into compatible server platforms that support mezzanine network adapters, often optimizing internal space usage.
