10Gb SFP+ Ethernet adapter for servers

The C&N ST7315 uses an Intel 82599EN controller to provide a single 10Gb SFP+ port over a PCIe 2.0 x4 slot. It targets administrators upgrading rack or tower servers that need deterministic 10Gb throughput and broad operating-system support.

Dual brackets and virtualization offloads

A 12cm standard bracket ships installed and an 8cm low-profile bracket is included, letting the card fit both full-height and slim chassis without extra parts. Hardware assists such as Flexible Port Partitioning, VMDq and PCI-SIG SR-IOV reduce CPU overhead when the adapter serves multiple virtual machines.

PCIe 2.0 x4 bandwidth and missing optics

The x4 Gen 2 link caps theoretical throughput at roughly 20Gb/s, so the 10Gb line rate is sustainable but leaves no headroom for a second 10Gb port on the same slot. No SFP+ transceiver, direct-attach or active-optical cable is bundled; those must be sourced separately. Mac OS is not supported.

Questions about this item

Will the SFP+ transceiver need replacing as the network grows?

The card accepts any SFP+ module, so you can swap transceivers for different reach or fibre type without changing the adapter.

Does the PCIe 2.0 x4 link cap sustained 10 Gbps throughput?

PCIe 2.0 x4 provides roughly 16 Gbps raw bandwidth, leaving headroom above the 10 Gbps line rate.

How much heat does the Intel 82599EN generate during all-day operation?

The controller is a passively cooled, low-power design; typical server airflow keeps it within thermal limits.
