# Chelsio Communications

> Chelsio Communications designs and sells high-performance Ethernet network adapters and ASICs — the Terminator (T4/T5/T6/T7) Unified Wire family — for virtualized enterprise datacenters, hyperscale clouds, cluster computing, GPU-accelerated computing and high-frequency trading. Its 1/10/25/40/50/100GbE adapters fully offload TCP, iSCSI, FCoE, iWARP RDMA and NVMe-oF on a single chip with single firmware; the T6 ASIC adds integrated cryptography offload for IPsec/TLS/SSL/DTLS.

Chelsio publishes **no public developer program, REST API, or machine-readable API contract**. Its
developer-facing surface is device drivers and management software distributed as downloads: the
Unified Wire packages for Linux, Windows, FreeBSD and VMware ESXi, the `cxgbtool` command-line
utility, and the Unified Wire Manager. Product and driver documentation is published as PDF from the
service portal; board, chip and reference-driver documentation are "available upon request."
