Openings in Chelsio
Chelsio Communications, a privately held subsystems company in Sunnyvale, California, is the market and technology leader in protocol engines and server adapters for 10 Gigabit Ethernet (10GbE).Chelsio provides products and solutions for the following applications:
- Enterprise data centers, connecting high-speed servers and storage systems to the data-center backbone
- High Performance Cluster Computing (HPCC), interconnecting servers in cluster and grid-computing architectures, and connecting these clusters together locally or over long distances (WAN) Storage target systems serving users over high-speed LANs or dedicated IP storage networks
Core Technology Chelsio’s flagship board-level protocol engine is the worlds best performing 10GbE adapter. It employs Chelsio’s unique Terminator ASIC that processes TCP/IP, iSCSI, and other upper-layer protocols – unburdening the host-system’s CPU of these tasks. Unlike competitive solutions that tax the host-system CPU to process these protocols, Chelsio’s TCP offload engine (TOE) technology dramatically increases the host-system’s CPU performance, as well as its network bandwidth
