High Performance, Single Port 40/50/100GbE Server Offload Adapter for Open Compute Project (OCP)
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 T61100-OCP for Open Compute Project (OCP) is a memory free single port 40/50/100 Gigabit Ethernet Server Offload adapter, with PCI Express 3.0 host bus interface, optimized for cloud computing, storage, HPC, virtualization and other datacenter applications in an Open Compute Network and Storage environment.
This adapter, based on the sixth-generation (T6), memory free technology from Chelsio, provides the highest performance and efficiency, dramatically lowers host-system CPU communications overhead and frees up host CPU cycles for useful applications. As a result, the system benefits from higher bandwidth, lower latency and reduced power consumption.
Chelsio memory free variant of the adapters doesn’t have any external memory on adapter and can offload a limited number of TOE, iSCSI and iWARP connections. Once offloaded connections limit is reached, the adapter falls back to host compute cycles without disturbing the network traffic. All other features and functionalities are supported transparently by T61100-OCP, similar to adapters with external memory on them. All variants of Chelsio adapters leverage single software stack (drivers/firmware/management tools) and support all protocols concurrently.
T61100-OCP 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.
Open Compute Project is a rapidly growing community of engineers to design and enable the delivery of the most efficient server, storage and datacenter hardware designs for scalable computing.
The Unified Wire Solution
The T61100-OCP 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, including LRO, LSO, RSS, virtualization, traffic management and security.
The T61100-OCP supports IEEE 802.3ad link aggregation/failover features that make it ideal for critical network applications requiring redundancy and high-availability capabilities.
T61100-OCP also includes an integrated Traffic Manager for robust flow control, traffic management, and QoS.
Chelsio Unified Wire 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 in-line TLS/SSL, PCIe SR-IOV virtualization with an embedded virtual switch.
High Performance Security Offload
T61100-OCP 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
T61100-OCP integrates a high performance packet switch, which allows switching traffic from any of the input ports to any of the output ports (wire-to-wire) and from any of the output ports to any of the input ports (host-to-host).
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.
Chelsio offers a full suite of protocol software drivers with the T61100-OCP adapters. See Support Page for the latest information. The software suite supports operation in both stateful and stateless offload modes for all major operating systems.
