Product Details

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 T5 is Chelsio's fifth-generation TCP offload (TOE) design, fourth-generation iSCSI design, and third-generation iWARP (RDMA) implementation. For the server connection, the T5 chip included a PCI Express V3.0 x8 host bus interface. With support for the 8 Gbps Gen 3 data rate, the PCIe interface provides up to 64Gbps for bandwidth to the server. T5 also provides support for PCIe I/O virtualization. On this external memory free version of the adapter, a maximum of 32 offloaded TCP/IP connections is supported that are meant to be used in a low round-trip-time (RTT) environment. Most of the T5 features are carried over fromthose found on T4.
