Lenovo Chelsio T440-CR Quad Port 10GbE PCI-E 2.0 Adapter

Chelsio T4-based 10GbE Unified Wire Adapters for IBM Intelligent Cluster

and iDataPlex

Product Guide (withdrawn product)
The Chelsio dual-port and quad-port Unified Wire adapters for IBM® Intelligent Cluster and IBM iDataPlex™ are 10 Gigabit Ethernet adapter with PCI Express host bus interface optimized for cloud computing, HPC, virtualization, storage, and other data center applications. These adapters are based on fourth-generation (T4) technology from Chelsio, provide the highest 10GbE performance available, and dramatically lower host-system CPU communications overhead with on-board hardware that offloads TCP/IP, iSCSI, FCoE, and iWARP RDMA processing from its host system. As a result, the server can achieve increased bandwidth, lower latency, and lower power consumption.
Figure 1 shows the Chelsio T440-CR Quad-Port (SFP+) 10GbE PCI-E 2.0 Adapter.

Did you know?
Chelsio implements the concept of the unified wire, enabling the convergence of server networking, storage networking, and cluster computing interconnects onto a single fabric that enables TCP, UDP, iSCSI, iWARP, and FCoE offload with SR-IOV, EVB/VN Tag, and data center bridging (DCB). These Chelsio adapters are part of the IBM Intelligent Cluster solution. IBM Intelligent Cluster is your key to a fully integrated HPC solution. IBM clustering solutions include servers, storage, and industry-leading interconnects that are factory-integrated, fully tested, and delivered to your door, ready to plug into your data center, all with a single point of contact for support.

Features

Chelsio is enabling a unified wire for LAN, SAN, and cluster traffic. This unified wire was made possible by the high bandwidth and low latency of 10GbE combined with storage and cluster protocols operating over TCP/IP (iSCSI, FCoE, and iWARP, respectively). In parallel, operating systems and hypervisors have incorporated native support for iSCSI, and database applications now support file-based storage protocols such as NFS as an alternative to SANs. Expanding its unified wire approach, Chelsio has added Fibre Channel over Ethernet (FCoE) hardware support to the new T4-based adapters. FCoE provides a transition path from legacy SANs to converged networks.
Chelsio Unified Wire 10GbE adapters for IBM Intelligent Cluster and iDataPlex have the following features:

• PCI Express Gen2 x8
• Low latency
• Supports up to 1M connections
• Full TCP and UDP offload
