The Chelsio Terminator 5 (T5) T520-SO-CR is a memory free dual-port, 10 Gigabit Ethernet Unified Wire Adapter with a PCI Express 3.0 x8 host bus interface, optimized for cloud computing, virtualization, storage, and other data center applications.


Low Cost, High Performance, Dual Port 10GbE Unified Wire Adapter, Enables connectivity over Single Unified Wire with SR-IOV, EVB/VNTag, DCB


Chelsio’s T520-SO-CR is a memory free dual-port 10 Gigabit Ethernet Unified Wire adapter with a PCI Express 3.0 host bus interface, optimized for cloud computing, virtualization, storage, and other data center applications.

The fifth generation (T5) technology from Chelsio provides the highest 10GbE performance available and lowers host-system CPU communications overhead with on-board hardware that does stateless off-loads for TCP/IP and UDP.

The Unified Wire Solution

With the T520-SO-CR, Chelsio is enabling a unified wire for LAN, SAN, and cluster traffic. This unified wire was made possible by the high bandwidth and low latency of 10GbE combined with storage and cluster protocols operating over TCP/IP (iSCSI and FCoE). In parallel, operating systems and hypervisors have incorporated native support for iSCSI and database applications are now supporting file-based storage protocols such as NFS as an alternative to SANs.

T520-SO-CR includes a full-fledged integrated Traffic Manager for robust flow control, traffic management, and QoS.

The adapter’s two ports and IEEE 802.3ad link aggregation/failover features are ideal for critical network applications that require redundancy and high-availability capabilities.

T520-SO-CR Ethernet-only networking reduces the data center’s cost in network adapters, cables, switches, rack space, power, equipment spares, management tools, planning, networking skills and installation.
