High Performance, Dual Port 40 GbE Unified Wire Adapter for Open Compute Project (OCP)
Enables Single Unified Wire with SR-IOV, EVB/VNTag, DCB
Chelsio’s T580-OCP-SO for Open Compute Project (OCP) is a memory free dual-port 40 Gigabit Ethernet Unified Wire adapter, with PCI Express 3.0 host bus interface, optimized for storage, cloud computing, HPC, virtualization and other data center applications in an Open Compute Network and Storage environment.
This adapter, based on the fifth-generation (T5) 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.
Open Compute Project is a rapidly growing community of engineers to design and enable the delivery of the most efficient server, storage and data center hardware designs for scalable computing.
The Unified Wire Solution
The T580-OCP-SO shares the high bandwidth and low latency architecture of other T5 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 T580-OCP-SO supports IEEE 802.3ad link aggregation/failover features that make it ideal for critical network applications requiring redundancy and high-availability capabilities.
T580-OCP-SO also includes an integrated Traffic Manager for robust flow control, traffic management, and QoS.
T580-OCP-SO Ethernet-only networking reduces the infrastructure costs in network adapters, cables, switches, rack space, power, equipment spares, management tools, planning, networking staff and installation.
The T5 is Chelsio’s fifth-generation ASIC. With support for the 8 Gbps Gen 3 data rate, the T5 ASIC PCIe interface provides 64 Gbps of raw bandwidth to the server. T5 also provides support for PCIe SR-IOV virtualization with embedded virtual switch.
Packet Switching and Routing
T580-OCP-SO 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 T580-OCP-SO adapters. See Support Page for the latest information.
