This article covers H!Fiber 10Gb SFP+ PCI-E ネットワークカード NIC インテル82599ESチップ搭載 デュアルSFP+ポート Intel X520-DA2 (E10G42BTDA) PCIe X8 イーサネットLANネットワークアダプター Windows.

Overview

The H!Fiber 10Gb SFP+ PCI-E Network Card is a dual-port 10 Gigabit Ethernet adapter built around the Intel 82599ES controller. Model number X520-DA2 (also known as E10G42BTDA) uses a PCI Express x8 interface and offers two SFP+ cages. This card is positioned as an entry-level 10GbE NIC, making it an affordable option for home lab enthusiasts and small businesses looking to upgrade their network backbone without breaking the bank. It supports SFP+ direct attach copper cables and LC fiber cables, delivering up to 10 Gbps per port. Power consumption is a modest 8.6W, and the card draws all power from the PCIe slot, so no additional power connector is needed.

Connectivity & Compatibility

The card uses a PCI Express x8 interface and can physically fit into x16 slots (electrically x8). It provides two independent SFP+ ports. Supported operating systems include Windows 7/8/10/11, Windows Server 2008/2012/2016/2019, CentOS/RHEL 6/7/8, Ubuntu 16/18/19/20, Debian 9/10/11, FreeBSD 10/11/12, VMware ESXi 6/7, and SLES 11/12. Important limitations: Mac OS and bypass mode are not supported. Windows 11 requires manual driver configuration using Windows 10 drivers. The card is not compatible with SFP-LX modules or QNAP QSW-308 series switches. For installation details, refer to the product images or video.

Product Info

This NIC is widely available on Japan at around ¥13,925. Warranty terms vary by seller, typically 30-day return. The package includes the card only; a low-profile bracket may need to be purchased separately. Market positioning is entry-level, offering Intel chipset reliability at a budget price point.

Best Use Cases

Home lab enthusiasts: Ideal for building a low-cost 10GbE test environment. The Intel chipset ensures good driver support and stability. Not suitable for those needing PCIe Gen4 bandwidth or enterprise-grade management features. Small office deployments: Connect NAS or file servers with dual-port redundancy or link aggregation. Cost-effective way to boost internal network speed. However, if you require full remote management or advanced firmware features, consider higher-end models. VMware homelab users: Officially supported on ESXi 6/7, making it easy to integrate into vSphere setups. Works well for VM migration and storage traffic. Not recommended for Mac OS or FreeBSD users. Budget-conscious DIY builders: Add 10GbE to a desktop without upgrading the PSU. Low power draw and simple installation. Overkill for gaming; stick with 1GbE if you don't transfer large files frequently.
