Intel Network Cards & Adapters
A server is only as fast as its network connection, and Intel's 10Gb Ethernet adapters are the industry-standard upgrade path once onboard gigabit networking becomes the bottleneck for virtualization, storage, or high-throughput application workloads. Arnav Infosystem stocks genuine Intel network adapters — including the Intel X710-DA2 dual-port 10Gb SFP+ PCIe adapter and the Intel X520-DA2 dual-port 10Gb SFP+ server adapter — alongside compatible SFP+ transceivers, all real, currently-stocked hardware. We also maintain a dedicated Intel brand catalog with several more genuine Intel products, so this page isn't the whole story — it's the network-card-specific slice of real Intel stock. Most buyers land here for one of two reasons: a specific server build spec calls for an Intel adapter by name, or an existing server's onboard gigabit NIC has become the bottleneck for a workload that's outgrown it — either way, the adapters below are real stock, not a manufacturer datasheet.
Features
What Intel's 10Gb adapters are actually built for:
- Dual-port 10Gb SFP+ PCIe
- Both the X710-DA2 and X520-DA2 give a server two independent 10Gb fibre uplinks on a single PCIe card.
- Broad OS/hypervisor driver support
- Mature, well-tested drivers across Windows Server, Linux distributions, and VMware ESXi.
- Virtualization & storage-network ready
- Low-latency, high-throughput design suited to VM traffic and iSCSI/NFS storage networking, not just general LAN traffic.
- Compatible SFP+ transceivers stocked
- Transceivers to match your adapter and switch uplink ship alongside the card, not as a separate sourcing exercise.
- PCIe 3.0 x8 interface
- Wide server and motherboard compatibility across most rack and tower server platforms sold in the last several years.
Why Buy From Arnav Infosystem
The X710-DA2 and X520-DA2 shown here are real, in-stock Intel network adapters, not a sourcing promise — genuine hardware, GST-invoiced, ready to ship. Our team can help you pick between them (the X710 generally offers newer feature support; the X520 is a proven, widely-compatible baseline) based on your server platform and OS. For the full range of genuine Intel products we carry beyond network cards, our dedicated Intel brand page has more. A lot of server upgrades stall on exactly this decision — which adapter model, and whether the transceiver you already own will actually work with it — so we'd rather confirm compatibility with your existing switch and cabling before you order than have a card arrive that needs a different transceiver than the one sitting in your rack.
Industries That Buy This
10Gb network adapters are a common upgrade path across:
- Data centres / server upgrades: Moving server networking from 1Gb to 10Gb as workloads grow.
- Virtualization environments: VMware/Hyper-V hosts needing more network throughput per host.
- Storage / SAN networks: iSCSI and NFS storage traffic that benefits directly from 10Gb bandwidth.
- IT integrators: Building custom servers to a spec that includes a specific 10Gb adapter.
- Software/dev companies: In-house server infrastructure needing a network throughput upgrade.

FAQ
What's the difference between the X710-DA2 and X520-DA2?
Both are dual-port 10Gb SFP+ adapters. The X710-DA2 is the newer generation with broader feature support; the X520-DA2 is a proven, widely-compatible baseline — either works well for most server upgrades.
Are these genuinely in stock, not sourced to order?
Yes, both adapters are real, currently-stocked hardware, GST-invoiced and ready to ship.
Do you stock compatible SFP+ transceivers?
Yes, compatible transceivers are available to pair with either adapter — ask us to confirm the right type for your switch.
What operating systems are supported?
Windows Server, major Linux distributions, and VMware ESXi all have mature driver support for both adapters.
Do you sell other genuine Intel products?
Yes — see our Intel brand page for the full range, including Xeon server processors.
Will this adapter work with my existing SFP+ switch and cabling?
In most cases yes — tell us your switch model and existing transceivers and we'll confirm compatibility before you order.
