This article covers FebSmart PCIE X8 インターフェイス.

Overview

The FebSmart X520-DA2 is a dual-port 10GbE SFP+ network card built around the Intel 82599ES controller. It uses a PCI Express X8 interface, offering a total bandwidth of 40Gbps. This card is designed to bring high-speed 10-gigabit connectivity to desktop PCs, servers, and NAS environments. Supporting 10GBASE-SR and 10GBASE-LR optical transceivers as well as SFP+ Direct Attach Copper (DAC) cables, the X520-DA2 provides flexibility for building LAN or SAN networks. It also includes Intel Data Direct I/O technology and virtualization features (VT-c, VMDq, SR-IOV), making it a reliable choice for data centers and virtualized setups.

Connectivity & Compatibility

The X520-DA2 features a PCI Express X8 lane interface and can be physically installed in X8 or X16 slots. Using an X4 slot will result in insufficient bandwidth and the card will not deliver full 10Gbps performance. Supported operating systems include Windows 7/8.x/10/11 (32/64-bit), Windows Server 2012/2012R2/2016/2019/2022, Linux (RHEL 8/9, SLES 15, Ubuntu 20.04/22.04 LTS, Debian 11), FreeBSD 13/14, and VMware ESXi. Driver installation is required for each OS (Windows drivers or Linux ixgbe driver). The two SFP+ ports support 10GBASE-SR (multimode fiber), 10GBASE-LR (singlemode fiber), or SFP+ DAC cables. Optical transceivers and LC fiber cables are not included and must be purchased separately.

Product Info

The FebSmart X520-DA2 is available on for approximately ¥10,575 (tax included). The package includes a full-height bracket pre-installed and a low-profile bracket in the box. Warranty details are provided by the manufacturer; please check the product page for specifics. Positioned as an entry-to-mid-range 10GbE network card, the X520-DA2 offers excellent value by combining the proven Intel 82599ES chipset with an affordable price point. It competes well with both Intel-branded and third-party alternatives in terms of cost-effectiveness.

Best Use Cases

Home lab and small office NAS users: Pair this card with a 10GbE-capable NAS to dramatically speed up large file transfers and backups. It supports iSCSI and NFS, making it ideal for storage networks. Note that your NAS must also have a 10GbE interface. Video editors and creative professionals: Sharing 4K/8K RAW footage over a network demands 10GbE bandwidth. The X520-DA2 enables multiple workstations to access high-resolution media files quickly, streamlining collaborative workflows. Ensure your switch and cabling are also 10GbE-rated. * IT engineers managing virtualized environments: With SR-IOV and VMDq support, this card can assign network resources directly to virtual machines, reducing overhead. It works well with VMware ESXi and Hyper-V.

Things to Consider

Before purchasing, verify that your motherboard has an available PCIe X8 or X16 slot. An X4 slot will bottleneck performance. Additionally, you will need to buy SFP+ transceivers or DAC cables separately, as they are not included. Driver installation is mandatory. On Linux, you may need to compile the ixgbe driver manually. Always check the supported OS version list to ensure compatibility with your system. ## FAQ
Q: Can this card work in a PCIe X4 slot? A: Physically yes, but bandwidth will be insufficient for full 10Gbps performance. Use an X8 or X16 slot for best results. Q: Does it come with a low-profile bracket? A: Yes, a low-profile bracket is included in the package. The card ships with a full-height bracket pre-installed. Q: Is Windows 11 supported? A: Yes, Windows 11 (32/64-bit) is supported. You will need to install the appropriate Intel drivers.
