All network cards include both Low-Profile and Full-Height brackets to fit any server chassis, backed by our 1-Month Replacement Warranty and fast delivery across India.

Shop By Speed: Upgrade Your Connectivity

Choosing the right Network Interface Card (NIC) is crucial for server performance. We offer solutions for every bandwidth requirement.

1. 10 Gigabit Ethernet (10GbE) SFP+ Cards

The standard for modern data centers. Perfect for connecting servers to high-speed switches or Shared Storage (NAS/SAN).

  • Intel X520-DA2 / X710: The industry favourite. Excellent driver support for VMware ESXi and Windows Server.
  • Mellanox ConnectX-3 / ConnectX-4: High-throughput, low-latency cards ideal for High-Performance Computing (HPC) and financial trading.

2. Gigabit Ethernet (1GbE) RJ45 Cards

Reliable copper connectivity for management networks and standard office traffic.

  • Intel I350-T2 / T4: The gold standard for virtualization. Supports SR-IOV and is widely used for building pfSense / OPNsense firewalls.
  • Broadcom NetXtreme: Cost-effective enterprise connectivity often found in Dell and HP servers.

3. Fibre Channel HBAs (8Gb / 16Gb)

Need to connect to a Storage Area Network? We stock QLogic and Emulex HBA cards for robust block-level storage access.

Buying Guide: Key Features to Look For

Connector Type: RJ45 vs. SFP+

  • RJ45 (Copper): Uses standard Cat6/Cat6a Ethernet cables. Best for distances under 100m and 1GbE/10GBASE-T networks.
  • SFP+ (Fiber/DAC): Uses optical transceivers or Direct Attach Copper (DAC) cables. Required for 10GbE and 25GbE speeds with lower latency and power consumption.

Chipset & Compatibility

Not all cards work with all software. If you are building a custom router (pfSense) or a Hypervisor (Proxmox/VMware), Intel Chipsets (like the 82599 or I350) are highly recommended due to their superior driver stability.

Form Factor

Ensure the card fits your case. At ServerDukan, we typically include both brackets:

  • Low Profile (LP): For 1U and 2U rack servers.
  • Full Height (FH): For 3U, 4U, and Tower servers.

The ServerDukan Promise: Genuine Hardware Only

The market is flooded with counterfeit network cards that drop packets and overheat. We guarantee authenticity:

  • Hologram Verification: We check for the manufacturer's Yottamark or hologram on Intel cards.
  • Traffic Testing: Cards are tested using iPerf to ensure they meet rated throughput speeds.
  • Clean Contacts: Gold PCIe fingers are cleaned to ensure immediate detection by your motherboard.
