Chelsio's T6225-CR is a dual-port 1/10/25Gb Ethernet unified wire adapter with a PCI Express 3.0 x8 host bus interface optimised for storage, cloud computing, HPC, virtualisation and other data centre networking applications.

The T6225-CR runs all the host software of its predecessor, the T5, unchanged, so that all previous software investments can continue to be used. It offers all the functions of the T5 plus support for integrated offloads of IPsec, TLS/SSL, DTLS and SMB 3.X Crypto.

The T6225-CR offers sub-microsecond end-to-end latency and offloads a wide range of typical storage, network and cloud protocols from the host CPU. This enables savings in acquisition, power and operating costs of the host CPU and significantly increases system performance.

A large proportion of the offloads enabled by the T6225-CR are based on standard TCP, IP and UDP protocols (such as iSCSI and iWARP) and can therefore be operated with a software peer or replaced with a lower performance software solution, providing the required reliability for enterprise customers and enabling phased installations in the data centre. It works with any existing switch infrastructure and does not rely on new functions such as DCB, PFC, ETS, etc.
