Hetai Tech X520-DA2 82599ES 10Gbps Dual Port PCI-E E10G42BTDA network card

SKU CH-H3DS-GV0KQ

Dual-port 10Gbps Ethernet server adapter with Intel 82599ES controller for PCI Express connectivity

  • Dual 10 Gbps ports deliver high-bandwidth connectivity
  • Intel 82599ES controller ensures reliable server-grade performance
  • PCI Express interface enables fast host communication
  • X520-DA2 model supports demanding data-center workloads
  • New condition guarantees full factory specification operation

Dual-Port 10Gbps Server Adapter

The Hetai Tech X520-DA2 is a dual-port PCI-E network card built around the 82599ES controller. It delivers two 10Gbps Ethernet connections for servers and workstations needing high-throughput wired links. The adapter suits IT teams upgrading rackmount or tower systems to faster network fabric.

Standard Low-Profile Bracket Included

The card ships with a low-profile bracket so it fits 1U and 2U chassis without extra parts. No software CDs or proprietary utilities are bundled; drivers come from the OS vendor or the chip maker. This keeps deployment simple for administrators who prefer standard in-box support.

PCI-E Gen 2 x8 Electrical Limit

The 82599ES controller uses a PCI-E 2.0 x8 interface, capping total bidirectional throughput at the bus limit. Slots wired for fewer lanes or older generations will reduce available bandwidth accordingly. The card cannot exceed the electrical ceiling of the host slot it occupies.

Questions about this item

Does the X520-DA2 require any firmware updates or SFP+ module replacements during its service life?

The card uses the 82599ES controller and supports standard SFP+ modules; firmware updates depend on the host operating system and switch compatibility, while modules are replaced only if link requirements change.

What throughput ceiling appears first when both 10Gbps ports run at full load continuously?

The PCIe interface and the 82599ES controller set the aggregate bandwidth limit at 10Gbps per port, so sustained line-rate traffic on both ports simultaneously reaches that ceiling first.

How much power does the E10G42BTDA draw and how hot does it get during all-day operation?

The dual-port 82599ES adapter is a passive, fanless design that draws modest power from the PCIe slot and relies on chassis airflow for cooling, so noise is limited to the system fans.
