Description: Chelsio T6225-SO-CR - Network adapter - PCIe 3.0 x8 low profile - 25 Gigabit SFP28 x 2
Mfr Part #: T6225-SO-CR
Chelsio's T6225-SO-CR is a dual port 1/10/25Gb Ethernet Server offload adapter, with a PCI Express 3.0 x8 host bus interface, optimized for storage, cloud computing, HPC, virtualization and other datacenter networking applications. T6225-SO-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-SO-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-SO-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.
- PCI Express Gen3 x8

- Sixth-generation protocol offload engine
T6 is Chelsio's sixth-generation TCP offload (TOE) design, fifth-generation iSCSI design, and fourth-generation iWARP (RDMA) implementation. With support for the 8 Gbps PCIe Gen3 data rate, it provides 128 Gbps of raw bandwidth. Also provides support for PCIe SR-IOV virtualization with embedded virtual switch.
- Complete and flexible TCP offload
The T6225-SO-CR transport engine executes programmable firmware and is configurable with hundreds of registers for protocol parameters, RFC compliance and offload control. It can offload protocol processing per connection, per-server, per-interface, while simultaneously providing complete stateless offload for non-offloaded connections (processed by operating systems stack running on host CPU). It also provides a flexible direct data placement capability for regular TCP sockets, with all the benefits of zero-copy and kernel bypass without rewriting the applications.
- High performance security offload
T6225-SO-CR introduces ground breaking TLS/SSL performance with inline cryptographic functions leveraging Chelsio's proprietary TCP/IP offload engine. Chelsio's full offload TLS/SSL is uniquely capable of 100Gb line rate performance. In addition, it can be used with inline mode for DTLS and in a traditional co-processor lookaside mode to accelerate IPsec, TLS/SSL with AES, SHA1 and SHA2 processing and SMB 3.X Crypto.
- Packet switching and routing
T6225-SO-CR integrates a 140-port high performance L2-L3 packet switch with integrated access control and flow control support, which allows switching traffic from any of the ports or host queues or physical or virtual functions to each other. The switch can further provide multicast and replication functions in ingress or egress direction. Typical use is for very high performance OVS offload.
