Chelsio T520-BT dual-port 10GBase-T low-profile network card

Chelsio Communications

Chelsio Communications T520-BT 2-port 10GBase-T network card

SKU CH-D6YW-E44PQ

Dual-port 10GBase-T network adapter with PCI Express 3.0 interface offloads TCP/IP, iSCSI, FCoE and iWARP RDMA processing from the host CPU

  • Dual 10 GbE ports for high-bandwidth server links
  • PCIe 3.0 host interface for modern server platforms
  • Hardware TCP/IP offload frees host CPU cycles
  • Unified wire runs LAN SAN and cluster traffic
  • Low-profile bracket fits dense rack enclosures

Dual 10GBase-T Adapter

The Chelsio T520-BT is a dual-port 10GBase-T network card built on a PCI Express 3.0 host interface. It targets storage, cloud computing, HPC and virtualization workloads in data centre environments. The fifth-generation T5 ASIC offloads TCP/IP, iSCSI, FCoE and iWARP RDMA processing from the host CPU.

Unified Wire Offload

On-board hardware offload handles LAN, SAN and cluster traffic simultaneously over a single Ethernet fabric. Supported protocols include iSCSI, FCoE and iWARP RDMA, reducing host-system CPU overhead. This architecture delivers higher bandwidth and lower latency while lowering overall power consumption for the server.

Data Centre Deployments

Suits administrators deploying unified 10GbE fabrics for block, file and RDMA storage traffic. Not intended for desktop PCs lacking a compatible PCIe 3.0 slot or low-profile bracket clearance. Buyers needing fibre connectivity or single-port designs should evaluate other form factors.

Highlights

  • PCIe 3.0 host interface for modern server platforms
  • Hardware TCP/IP offload frees host CPU cycles
  • Unified wire runs LAN SAN and cluster traffic
  • Low-profile bracket fits dense rack enclosures

Questions about this item

Does the T520-BT have any field-replaceable parts that will need swapping later?

The card is a single assembly with no user-serviceable modules or replaceable transceivers, so no field-replaceable parts are expected to need swapping.

What is the first limit reached when the adapter runs at 10 Gb/s continuously?

The PCI Express 3.0 x8 host interface sets the maximum sustained throughput ceiling for the dual 10GBase-T ports.

How much heat and noise does the T520-BT produce under all-day load?

The low-profile design uses passive cooling, so it adds no fan noise and relies on chassis airflow to dissipate heat from the T5 ASIC.
