eshinreal 10G RJ45 network card M.2 NVMe 82599

SKU CH-AXTM-JA0J0

Converts an M.2 NVMe slot to a single 10G RJ45 port using an Intel 82599 controller with SATA power and SAS cabling

  • Class10G RJ45
  • Converts an M.2 NVMe slot to a 10G RJ45 port
  • Single 10G RJ45 port runs at 1Gbps and 10Gbps
  • Jumbo frames up to 15.5KB boost large-transfer efficiency
  • PXE and UEFI support enables remote OS deployment
  • Powered by a SATA 15-pin plug for stable operation

M.2 NVMe to 10G RJ45 adapter

This adapter converts an M.2 NVMe slot running at PCIe Gen 2.0 x4 into a single 10G RJ45 copper port. It is built on the Intel 82599 controller and includes a SAS cable for the connection. The card requires a SATA 15-pin power plug to operate. It suits builders who want 10G networking without consuming a PCIe slot.

Suits M.2 NVMe slots only; no SATA support

The device works exclusively with M.2 NVMe interfaces and does not support M.2 SATA drives. It provides one RJ45 port with 1 Gbps and 10 Gbps link speeds, plus jumbo frames up to 15.5 KB. PXE and UEFI boot are supported for remote deployment. Builders with only M.2 SATA slots or no spare NVMe slot should look at something else.

Sustained 10G throughput with SR-IOV virtualization

The Intel 82599 controller maintains line-rate 10 Gbps traffic over extended transfers thanks to jumbo frame support up to 15.5 KB. SR-IOV allows virtual machines to achieve near-native I/O performance without hypervisor overhead. Continuous operation depends on adequate airflow around the M.2 area and a stable SATA power connection.

Questions about this item

What M.2 slot and PCIe generation does this 82599-based card need?

It requires an M.2 NVMe slot wired for PCIe Gen 2.0 x4; M.2 SATA slots are not supported.

Will the 10G RJ45 port on this adapter link at 1Gbps with my existing Cat5e patch panel?

Yes, the single 10G RJ45 interface negotiates both 1Gbps and 10Gbps, so it will fall back to 1Gbps on Cat5e cabling.

How can I confirm the 82599 controller is active after I connect the SAS cable and SATA 15-pin power?

The adapter should appear in BIOS/UEFI with PXE and UEFI boot options visible, and the OS should detect a 10G Ethernet device using the 82599 driver.
