How many network ports does the HPE Mellanox 682148-B21 provide?

The adapter is described as a Mellanox 10Gb 1-port SFP+ ConnectX-3 FlexibleLOM Adapter. This indicates it provides a single network port. That port is based on an SFP+ interface, designed to deliver one 10GbE connection per adapter to the connected network infrastructure.

What type of network interface does the HPE 682148-B21 use?

The HPE 682148-B21 uses an SFP+ interface, as indicated by its description as a 10Gb 1-port SFP+ ConnectX-3 adapter. SFP+ is the small form-factor pluggable interface commonly used for 10GbE connections. This allows the use of appropriate SFP+ modules or cabling that match existing 10GbE deployments.

What form factor does the HPE Mellanox 10Gb 1-port SFP+ adapter use?

The adapter is classified as a 10 Gigabit Ethernet FlexibleLOM Adapter. FlexibleLOM is a modular form factor used in certain HPE servers for network adapters. This means the 682148-B21 is intended to be installed in HPE platforms that support FlexibleLOM network modules rather than in a standard PCIe slot.

Which technology family does the HPE 682148-B21 adapter belong to?

The product is identified as a Mellanox 10Gb 1-port SFP+ ConnectX-3 FlexibleLOM Adapter. This places it within the Mellanox ConnectX-3 technology family. For planning purposes, this helps align driver, firmware, and feature expectations with other Mellanox ConnectX-3 based network interfaces in the environment.
