Chelsio Communications is a privately-held company headquartered in Sunnyvale, California with a design center located in Bangalore, India. Chelsio is a market and technology leader enabling the convergence of networking, storage and clustering traffic over high speed Ethernet. With the proliferation of massive data centers, equipment density and power consumption are more critical than ever. At the same time cloud computing and server virtualization are driving the need for more uniform designs than the traditional data-center architectures can offer. With its proven Terminator ASIC technology designed in more than 200 OEM platforms and the successful deployment of more than 1.1 million ports, Chelsio has enabled unified wire solutions for LAN, SAN and cluster traffic. With its unique ability to fully offload TCP, iSCSI and iWARP protocols on a single chip, Chelsio’s adapter cards unburden communications responsibilities and processing overhead from servers and storage systems, resulting in a dramatic increase in application performance. And with its sixth generation T6 technology, Chelsio has taken the unified wire to the next level with full offload for TCP, UDP, iSCSI, iWARP and FCoE. Network convergence over 10Gb Ethernet and now 100Gb with T6 Ethernet is happening now, and Chelsio is a driving force behind the consolidation.
