Terminator 5 Adapter Range

High Performance, Dual Port 40/50/100GbE OCP 3.0 Server Offload Adapter

Enables TCP, UDP, iSCSI, iWARP, NVMe/TCP, FCoE, TLS/SSL, DTLS, NGINX, IPsec, SMB 3.X crypto, and SDN over Single Unified Wire with SR-IOV, EVB/VNTag and DCB


Chelsio’s T62100-SO-OCP3 is a dual port 40/50/100Gb Ethernet OCP 3.0 (Open Compute Project) Server Offload adapter, with PCI Express 3.0 host bus interface, optimized for cloud computing, storage, HPC, virtualization, security, and other datacenter applications in an Open Compute environment. OCP NIC 3.0 specification allows users to utilize compact server designs that can accommodate high-performance adapters.

T62100-SO-OCP3 based on the sixth-generation (T6), server offload technology from Chelsio provides the highest performance and efficiency, sub micro-second end-to-end latency, dramatically lowers host system CPU communications overhead and frees up host CPU cycles for useful applications. This will enable savings in host CPU acquisition costs, power and operational costs, and dramatically increases system performance.

Chelsio server offload variant of the adapters doesn’t have any external memory on them and can provide extensive support for L2 NIC, Virtualization, Filtering, and Traffic Management operations. All other features and functionalities (iSCSI, NVMe/TCP, iWARP, NGINX, TLS/SSL, IPsec, etc.) are supported by T62100-SO-OCP3 in non-offload mode (processed by operating systems stack running on the host CPU). All variants of Chelsio adapters leverage a single software stack (drivers/firmware/management tools) and support all protocols concurrently.

T62100-SO-OCP3 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.


The Server Offload Solution

The T62100-SO-OCP3 shares the high bandwidth and low latency architecture of other T6 products. It forms the basis of high-performance server adapter designs with a full suite of stateless offloads – Checksum, Segmentation (TSO/LSO), LRO, RSS, virtualization, traffic management, and security.

The T62100-SO-OCP3 supports IEEE 802.3ad link aggregation/failover features that make it ideal for critical network applications requiring redundancy and high-availability capabilities. It also includes an integrated Traffic Manager for robust and flexible flow control, traffic management, QoS, DCB, PFC, ETC etc.

Chelsio Ethernet-only networking solution reduces the infrastructure costs in network adapters, cables, switches, rack space, power, equipment spares, management tools, planning, networking staff, and installation.


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, the T6 host interface provides 128Gbps of raw bandwidth. Also provides support for PCIe SR-IOV virtualization with an embedded virtual switch.


High-Performance Security Offload

T62100-SO-OCP3 introduces ground breaking crypto performance. Chelsio’s crypto accelerator can be used in a traditional co-processor lookaside mode to accelerate IPsec, TLS/SSL with AES, SHA1 and SHA2 processing, SMB 3.X crypto, data at rest encryption/decryption, and data-deduplication fingerprint computations.


Packet Switching and Routing

T62100-SO-OCP3 integrates a 264-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.


Robust, Proven Solution

Subjected to thousands of hours of compatibility testing, over a decade of stress testing by several OEM test suites, and production deployment in servers, storage systems and cluster computing, Chelsio’s robust technology delivers proven performance in a wide range of environments.
