Product Details
High Performance, Low Profile, Dual Port 1/10/25GbE Unified Wire Adapter
Enables TCP, UDP, iSCSI, iWARP, FCoE, TLS/SSL, DTLS, IPsec, SMB 3.X crypto, and SDN Offload over Single Unified Wire with SR-IOV, EVB/VNTag and DCB

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, 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.

The Unified Wire Solution
T6225-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 T6225-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.
