SMUGDESK

SMUGDESK X520-DA1 Single Port 10G SFP+ PCIe 2.0 x8 NIC

SKU CH-KGTW-HXD8Z

Single-port 10G SFP+ PCIe 2.0 x8 adapter with Intel 82599EN controller, SR-IOV and VMDq virtualization offload, 9000 MTU jumbo frames, and full-height plus low-profile brackets

  • 10 Gbps throughput with Intel 82599EN controller
  • Flexible SFP+ slot accepts all-brand modules and cables
  • PCIe 2.0 x8 fits x4 x8 x16 slots with both brackets
  • Enterprise offloads cut CPU load under heavy traffic
  • Broad OS support Windows Server Linux VMware ESXi FreeBSD

Single-Port 10G SFP+ Adapter

The SMUGDESK X520-DA1 adds one 10 Gbps SFP+ connection to a server or workstation through a PCIe 2.0 x8 slot. It uses the Intel 82599EN controller and accepts any brand of SFP+ optical module, direct-attach copper cable or active optical cable. Full-height and low-profile brackets are included so the card fits both rackmount and compact chassis.

Capacity And Headroom

The single port delivers 10 Gbps throughput with 9000 MTU jumbo frame support for large-block storage traffic. PCIe 2.0 x8 supplies 16 GT/s of bus bandwidth, giving headroom above the line rate, while SR-IOV, VMDq, RSS and MSI-X offloads reduce host CPU load under sustained loads. TCP, UDP, IPv4 and IPv6 checksum offload further preserves processor cycles for applications.

PCIe 2.0 x8 Interface Limits

The card operates at PCIe 2.0 speeds and is backward compatible with x4, x8 and x16 slots, though an x4 slot halves available bus bandwidth to 8 GT/s. A passive heatsink enables continuous 24/7 operation without active cooling. Features such as PXE and UEFI boot, iSCSI and FCoE offload, IEEE 802.3Q VLAN tagging and IEEE 1588 clock synchronization target storage clusters and virtualised environments.

Questions about this item

Will the PCIe 2.0 x8 card run in my older motherboard that only has a PCIe x4 slot?

Yes, the interface is backward compatible with PCIe x4, x8 and x16 slots so it will function in an x4 slot at reduced bandwidth.

Which indicator shows the Intel 82599EN controller has negotiated a 10G link after I install the SFP+ module?

The link LED on the bracket lights solid when a 10 Gbps connection is established with a compatible module or DAC cable.

Does the box include an SFP+ transceiver or do I need to buy one separately?

The card ships with full-height and low-profile brackets only; any SFP+ optical module, DAC copper cable or AOC active optical cable must be purchased separately.
