Chelsio's T520-LL-CR is a dual-port, ultra-low latency 10 Gigabit Ethernet unified wire adapter with a PCI Express 3.0 host bus interface, optimized for financial and HPC applications. The T520-LL-CR is an excellent interconnecting solution for cloud computing, virtualization, storage, and other data center applications. The Teminator 5 technology provides the exceptional 10 GbE performance and dramatically lowers host-system CPU communications overhead with onboard hardware that offloads TCP/IP, iSCSI, FCoE, and iWARP RDMA processing from the host system and frees up host CPU cycles for other applications. As a result, the system benefits from higher bandwidth, lower latency, and reduced power consumption.

The T520-LL-CR enables a unified wire for LAN, SAN, and cluster traffic, made possible by the high-bandwidth and low-latency characteristics, combined with storage and cluster protocols operating over Ethernet (iSCSI, FCoE, and iWARP). T5 based adapters such as the T520-LL-CR support both file- and block-based storage protocols and are ideal for building high-performance SAN and NAS solutions. With both iSCSI and FCoE offload, FC applications can run natively over Ethernet, while taking advantage of its performance benefits and economies of scale. T5 also offers an ultra-low latency RDMA over Ethernet (iWARP) interface, making the T520-LL-CR an advanced drop-in replacement in high-performance computing applications. T520-LL-CR integrates a full-fledged hardware traffic manager for robust flow control, traffic management, and predictable QoS. The adapter's two ports and IEEE 802.3ad link aggregation, and port-to-port and adapter-to-adapter failover features are ideal for critical network applications that require redundancy and high-availability capabilities. T520-LL-CR Ethernet-only unified networking reduces the data center's cost in adapters, cables, switches, rack space, power, equipment spares, management tools, planning, installation, and operation.
