Chelsio Communications T6425-CR - 4-Port 10/25GBE Half Size Uwire Adapter

Chelsio's T6425-CR is a quad port ultra-low latency 1/10/25Gb 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. The host machine should support PCIE bifurcation to enable all the 4 Ports of T6425-CR. Otherwise only 2 ports will be enabled. It 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. T6425-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 T6425-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. T6425-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. It also includes an integrated Traffic Manager and a built-in eSwitch for robust network traffic flow control traffic classifier load balancer Firewall capabilities at the port level. FCoE and iSCSI support in T6425-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. The Unified Wire Solution T6425-CR enables a unified wire for LAN SAN and cluster applications built upon a high bandwidth and low latency architecture along with a complete set of storage and cluster protocols operating over Ethernet (iSCSI NVMe-oF FCoE and iWARP). A unified wire means having the ability to utilize all offload or non-offload protocols at the same time over the same link using the exact same firmware host software and adapter. Thus a given system using T6425-CR can be easily targeted at different vertical markets and a variety of useful functions enabled (i.e. dial the bandwidth to a given application and assign access control while offloading only part of the traffic). The Ethernet-only networking thus reduces the infrastructure costs in network adapters cables switches rack space power equipment spares management tools planning networking staff and installation.
