Chelsio T520-SO-CR - Network adapter - PCIe 3.0 x8 - 10 Gigabit SFP+ x 2
-
The unified wire solution
With the T520-SO-CR, 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. In parallel, operating systems and hypervisors have incorporated native support for iSCSI and database applications are now supporting file-based storage protocols such as NFS as an alternative to SANs. Fiber Channel over Ethernet (FCoE) provides a transition path from legacy SANs to converged networks. Expanding its unified wire approach, Chelsio has added FCoE hardware support for the adapter. The adapter's two ports and IEEE 802.3ad link aggregation/failover features are ideal for critical network applications that require redundancy and high-availability capabilities. T520-SO-CR Ethernet-only networking reduces the data center's cost in network adapters, cables, switches, rack space, power, equipment spares, management tools, planning, networking skills and installation.

T5
The T5 is Chelsio's TCP offload (TOE) design, iSCSI design, and iWARP (RDMA) implementation. For the server connection, the T5 chip included a PCI Express v3.0 x8 host bus interface. T5 also provides support for PCIe I/O virtualization.
-
Complete and flexible TCP offload
The T5 has hundreds of programmable registers for protocol configurations, RFCs, and offload control. The T520-SO-CR can offload processing per connection, per-server, per-interface, and globally and simultaneously tunnel traffic from non-offloaded connections to the host processor for the native TCP/IP stack to process. The T520-SO-CR provides a flexible zero-copy capability for regular TCP connections, requiring no changes to the sender, to deliver line rate performance at minimal CPU utilization.
-
Packet switching and routing
T520-SO-CR 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
Chelsio's robust, stable protocol offload technology delivers proven performance in a wide range of environments. The T520-SO-CR is generations ahead of competing products.
Chelsio's T520-SO-CR is a memory free dual-port 10 Gigabit Ethernet unified wire adapter with a PCI Express 3.0 host bus interface, optimized for cloud computing, virtualization, storage, and other data center applications. This adapter provides high performance and dramatically lowers host-system CPU communications overhead with on-board hardware that off-loads TCP/IP processing from its host system. T520-SO-CR frees up host CPU cycles for useful applications. The system achieves increased bandwidth, lower latency, and uses less power.
