chelsio T520-SO-CR 双口万兆光纤网卡

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, virtualizati*torage, and other data center applicati*.

This adapter, based on the fifth-generation (T5) technology from Chelsio provides the h 10GbE performance *ailable and dramatically lowers host-system CPU communicati* overhead with on-board ha*are that off-loads TCP/IP processing from its host system. T520-SO-CR frees up host CPU cycles for useful applicati*. The system achieves increased bandwidth, lower latency, and uses less power.

With the T520-SO-CR, Chelsio is enabling a unified wire for LAN, SAN, and cluster traffic. This unified wire wa*ade *sible by the bandwidth and low latency of 10GbE combined with storage and cluster protocols operating over TCP/IP. In parallel, operating systems and hypervisors h*e incorporated native support for iSCSI and database applicati* are now supporting file-based storage protocols such as NFS as an alternative to SANs.

T520-SO-CR includes a full-fledged integrated Traffic Manager for robust flow co*ol, traffic management, and QoS.

Fibre Channel over Ethernet (FCoE) provides a transition path from legacy SANs to converged networks. Expanding its unified wire approach, Chelsio has added FCoE ha*are support for the adapter.

The adapter’s two ports and IEEE 802.3ad link a*regation/failover features are ideal for critical network applicati* that require redundancy and -*ailability capabilities.

T520-SO-CR Ethernet-only networking reduces the data center’s cost in network adapters, cables, switches, rack *ce, power, equipmee*anagement tools, planning, networking skills and installation.

The T5 is Chelsio’s fifth-generation TCP offload (TOE) design, fourth-generation iSCSI design, and thi*eneration iWARP (RDMA) implementation. For the server connection, the T5 chip included a PCI Express v3.0 x8 host bus interface. With support for the 8 Gbps Gen 3 data rate, the PCIe interface provides up to 64 Gbps for bandwidth to the server. T5 also provides support for PCIe I/O virtualization. On this External Memory Free version of the adapter, a maximum of 32 offloaded TCP/IP connecti* is supported that are meant to be used in a low Round-Trip-Time (RTT) environment. Most of the T5 features are carried over from those found on T4

The T5 has hundreds of programmable registers for protocol configurati*, RFCs, and offload co*ol. The T520-SO-CR can offload processing per connection, per-server, per-interface, and globally and simultaneously tunnel traffic from non-offloaded connecti* 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 connecti*, requiring no changes to the sender, to deliver line rate performance at minimal CPU utilization.

T520-SO-CR integrates a 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).

Subjected to thousands of hours of compatibility testing, over multiple years of stress testing by several OEM test suites and production deployment in servers, storage systems, and cluster computing, Chelsio’s robust, stable protocol offload technology delivers proven performance in a wide range of environments. The T520-SO-CR is generati* ahead of competing products.

Chelsio offers a full suite of protocol software drivers with the T520-SO-CR adapters. See Support Page for the latest information. The software supports operation in both protocol-offload and non-offload modes.
