Chelsio T6225-CR - Network adapter - PCIe 3.0 x8 - 25 Gigabit SFP28 x 2

Chelsios T6225-CR is a dual port 1/10/25 Gb Ethernet Unified Wire Adapter, with a PCI Express 3.0 x8 host bus interface, optimized for storage, cloud computing, HPC, virtualization and other datacenter networking applications. T6225-CR runs all the host software of its predecessor, T5, as-is, thus enabling leveraging of all the prior software investment. It offers all the features of T5, and in addition adds support for integrated offload of IPsec, TLS/SSL, DTLS and SMB 3.X crypto. T6225-CR provides sub micro-second end-to-end latency, while offloading the host CPU from a variety of typical storage, networking, and cloud related protocols. This will enable savings in host CPU acquisition costs, power and operational costs, and dramatically increases system performance. A large portion of offloads enabled by T6225-CR are based on standard TCP, IP, UDP protocols (such as iSCSI and iWARP), and thus can operate with a software peer, or be replaced with a software solution at lower performance, thus providing the requisite reliability for enterprise customers, and allowing incremental installs in the datacenter. It will work with any legacy switch infrastructure and does not rely on new features such as DCB, PFC, ETS, etc. T6225-CR supports IEEE standards-based link aggregation/failover features, as well as inter-adapter failover techniques that make it ideal for critical network applications requiring redundancy and high-availability capabilities. T6225-CR also includes an integrated Traffic Manager for robust and flexible flow control, traffic management and QoS. FCoE and iSCSI support in T6225-CR benefit from high reliability features that include memory ECC, data path CRC and T10-DIX offload, in addition to the checksums and CRC available at different protocols layers. High performance iSCSI and FCoE provide a drop-in replacement upgrade from legacy SANs to converged networks. 32K concurrent offloaded conn. capacity Full iWARP RDMA offload OVS Offload with OpenFlow support Full TLS/SSL, DTLS, IPsec, SMB 3.X crypto offload Full TCP and UDP offload PCI Express Gen3 x8 Low latency user-space I/O Full NVMe over Fabrics (NVMe-oF) offload Full iSCSI, FCoE offload DPDK (Data Plane Development Kit)
