Dual-port server NIC for virtualised hosts

The Vszerda 82576-2T-X1-US adds two Gigabit Ethernet ports through a single PCIe 2.0 x1 lane using the Intel 82576 controller. It targets administrators who need extra copper links for VM traffic, backup networks or management segregation on Windows Server, Linux or VMware ESX/ESXi 5 and 6 hosts.

Passive cooling keeps noise at zero

The card draws power only from the slot and uses a passive heatsink, so it adds no audible fan noise to rack or tower chassis. Intel intelligent offloads handle checksum and segmentation tasks in hardware, reducing host CPU load during sustained 1000 Mbps transfers over Category-5 cable runs up to 100 metres.

Two brackets cover standard and slim chassis

A low-profile bracket and a full-height bracket are both included, letting the same card fit 1U servers or full-size workstations without extra parts. Drivers are downloaded from the Intel website or via the QR code printed on the PCB; note that VMware ESXi 7.0 and later are not supported.

Questions about this item

How do I install the Vszerda 82576-2T-X1-US in a standard or slim chassis?

Fit the full-height bracket for standard cases or the low-profile bracket for slim servers, insert the card into any PCIe x1, x4, x8 or x16 slot, then download the Intel 82576 driver from Intel's website or scan the QR code on the card.

What maintenance or replacement will the Intel 82576 dual-port card need later?

The card has no moving parts or user-serviceable components; keep the RJ45 ports dust-free and replace the Cat5e cabling if it exceeds 100 metres or shows physical damage.

What limit appears first under sustained 1 Gbps traffic on this PCIe 2.0 x1 card?

The PCIe 2.0 x1 lane provides 2.5 GT/s bandwidth, which caps total throughput below the combined 2 Gbps line rate of the dual Intel 82576 ports during heavy simultaneous loads.
