Dual 10 GbE RJ45 adapter for servers
The Alphacool Intel X540-T2 adds two 10 GbE copper ports to a server or workstation through a PCIe x8 slot. It targets administrators who need 10 GbE over existing Cat 6a cabling up to 100 m or Cat 6 up to 55 m. The card includes both low-profile and full-height brackets for flexible chassis fit.
PCIe 2.1 x8 interface and copper reach
The adapter uses a PCIe 2.1 link at 5.0 GT/s with x8 electrical width, also compatible with x16 slots. On the wire side the on-chip PHY negotiates 10 GbE, 1 GbE or 100 Mb/s over twisted pair. Jumbo frames up to 15.5 KB are supported, as are 802.1Q VLANs and Data Center Bridging. The card operates from 0 °C to 55 °C and does not support hot-swap insertion.
Two ports for iSCSI, FCoE or NFS storage
Dual ports give redundancy or link aggregation for storage traffic such as iSCSI, FCoE or NFS. A single 10 GbE lane saturates near 10 Gb/s, so sustained sequential workloads will hit the wire-rate ceiling. Workloads needing more than two 10 GbE links or fibre media require additional adapters.

商品問答
Should I pick the high-profile or low-profile bracket for my case?
Both brackets are included — use the high-profile bracket for standard ATX cases and the low-profile bracket for small-form-factor or 1U servers.
What real-world throughput can I expect from the 10GBASE-T ports?
The card delivers up to 10 Gbps per port over Cat6a cable up to 100 m, or Cat6 up to 55 m, with jumbo frames up to 15.5 KB for lower CPU overhead.
Does PCIe 2.1 x8 limit the 10 GbE speed?
The x8 lane at 5.0 GT/s provides enough bandwidth for dual 10 GbE line-rate traffic, so the interface does not cap performance.
