This article covers ipolex 10Gネットワークカード Intel X520-DA1.
Overview
The ipolex 10G network card brings Intel 82599EN silicon to a single SFP+ PCIe 2.0 x8 form factor at a wallet-friendly price. Aimed at home lab enthusiasts and small-office users who want 10 Gigabit Ethernet without breaking the bank, this adapter delivers genuine Intel chipset stability plus virtualization features like SR-IOV and VMDq. It works with standard SFP+ modules or direct-attach copper cables, making it flexible for various wiring setups. As a third-party product carrying an authentic Intel controller, this card fits into any PCIe x8 or x16 slot (mechanical compatibility) and supports Windows Server, Linux, and ESXi out of the box. However, Windows 11 users should be aware that native driver support has ended, though a manual installation guide is provided by the seller. The card is not hot-pluggable and requires a cold boot to be recognized.
