IBM Intel X520-DA2 10GbE Dual Port SFP+ Network Card 49Y7961

SKU CH-RBGJ-2QZYZ

A dual-port 10GbE SFP+ adapter on a PCIe 2.0 x8 interface using the Intel 82599ES chipset

  • Dual 10 GbE ports accelerate data-intensive workloads
  • PCI Express 2.0 x8 interface ensures efficient server integration
  • Intel 82599ES chipset delivers reliable high-speed networking
  • Two SFP+ slots enable flexible fibre or copper connectivity
  • Part 49Y7961 guarantees compatibility with select IBM systems

Dual-port 10GbE SFP+ adapter for enterprise servers

The IBM 49Y7961 Intel X520-DA2 provides two 10 Gigabit Ethernet SFP+ ports for high-speed, low-latency networking. It targets data-centre, cloud and virtualisation workloads that demand consistent throughput. The card uses the Intel 82599ES chipset and connects through a PCI Express 2.0 x8 slot.

Passive cooling suited to managed airflow

The adapter relies on system airflow rather than an onboard fan, so it adds no acoustic load in a properly cooled rack chassis. Power draw is modest for a dual-port 10GbE controller, keeping thermal contribution low inside dense server configurations. No auxiliary power connectors are required.

PCIe 2.0 x8 slot and SFP+ optics required

Installation needs a free PCI Express 2.0 x8 lane and compatible SFP+ transceivers or direct-attach cables for each port. The half-height bracket fits standard server chassis without blocking adjacent slots. Part number 49Y7961 confirms validated compatibility with select IBM systems.

Questions about this item

How do I install the IBM 49Y7961 Intel X520-DA2 into a PCI Express 2.0 x8 slot, and what step is often missed?

Insert the card firmly into an available PCIe 2.0 x8 slot, secure the bracket screw, then attach compatible SFP+ transceivers and cables to the two ports; the step often missed is installing the correct driver for the Intel 82599ES chipset before expecting link lights.

What maintenance or replacement will the dual-port 10GbE SFP+ adapter need over time?

The adapter itself has no moving parts, but the SFP+ transceivers inserted into its two ports are consumable optics that may need replacement if links degrade or speeds change; keep spare modules matching your fibre or copper media.

What limit appears first on the Intel X520-DA2 when sustaining 10 Gb/s traffic on both ports?

The PCI Express 2.0 x8 host interface provides the ceiling; combined throughput above its bandwidth will queue at the chipset before the 10GbE line rate becomes the bottleneck.
