Chelsio Communications

Chelsio Communications is a technology company that specializes in the development and distribution of networking and storage solutions. They are known for their high performance, 1/10/25/40/50/100Gb Ethernet Unified Wire adapters and ASICs (Application Specific Integrated Circuits) for storage networking, virtualized enterprise datacenters, cloud service installations, and cluster computing environments.

Chelsio's primary product lines include:

iWARP (Internet Wide Area RDMA Protocol): Chelsio's iWARP is known for its performance in Ethernet networking, providing RDMA (Remote Direct Memory Access) over Ethernet, a technology that allows data to move directly from the memory of one computer into that of another without involving either one's operating system. This improves throughput, reduces CPU utilization, and eliminates network bottlenecks.

TCP Offload Engine (TOE): Chelsio offers high performance, robust third-generation protocol offload technology, built around a reliable, connection-oriented, low-latency, transport mode protocol. It enables direct data placement, dramatically lowers host-system processing overhead and powers the industry’s leading Unified Wire Solution.

iSCSI: This technology allows clients (called initiators) to send SCSI (Small Computer System Interface) commands (CDBs) to SCSI storage devices (targets) on remote servers. It is a popular storage area network (SAN) protocol, allowing organizations to consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks.

Network Adapter Cards and Silicon: Chelsio also manufactures adapter cards and proprietary silicon solutions, aimed at driving the performance of server clusters over Ethernet.
