QNAP SP-E10G-SFP+-DAC Dual-Port 10GbE Card SFP+ DAC

The QNAP SP-E10G-SFP+-DAC is a dual-port 10 Gigabit Ethernet expansion card engineered specifically for QNAP's TS-x79 series network-attached storage systems. Built around the Emulex OCe11102-NX controller, it delivers two independent 10GbE SFP+ ports that can dramatically increase network throughput compared to the standard 1GbE connections found on these NAS units. For workflows involving large file transfers, video editing over the network, virtualization storage (iSCSI), or environments with many simultaneous users, the jump from 1GbE to 10GbE can be transformative — effectively removing the network as a bottleneck and letting the NAS drives operate closer to their actual throughput potential.

The SFP+ interface offers deployment flexibility: DAC cables provide a cost-effective, low-latency solution for short-distance connections within the same rack or room, while SFP+ optical transceivers enable longer fiber runs between floors or buildings. The dual-port design supports link aggregation for increased bandwidth or failover redundancy, depending on your switch and network configuration. Installation is straightforward — the card slots into a PCIe expansion bay on compatible TS-x79 models and is recognized natively by QNAP's QTS operating system. While the card's compatibility is limited to the TS-879 Pro, TS-1079 Pro, and their rack-mounted counterparts, it remains a practical and effective upgrade for organizations still running these capable NAS platforms.
