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Product Guide (withdrawn product)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.
Part number information
Table 1 lists part numbers and feature codes. Table 1. Ordering part number and feature code
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
