Chelsio's T62100-SO-CR is a dual port 40/50/100Gb Ethernet Server Offload Adapter with a PCI Express 3.0 x16 host bus interface optimized for storage cloud computing HPC virtualization and other datacenter networking applications.

T62100-SO-CR runs all the host software of its predecessor T5 as-is thus enabling leveraging of all the prior software investment. It offers all the features of T5 and in addition adds support for integrated offload of IPsec TLS/SSL DTLS and SMB 3.X crypto.

This adapter based on the sixth-generation (T6) memory free technology from Chelsio provides the highest performance and efficiency dramatically lowers host-system CPU communications overhead and frees up host CPU cycles for useful applications. As a result the system benefits from higher bandwidth lower latency and reduced power consumption.

Chelsio memory free variant of the adapters doesn't have any external memory on adapter and can offload a limited number of TOE iSCSI and iWARP connections. Once offloaded connections limit is reached the adapter falls back to host compute cycles without disturbing the network traffic. All other features and functionalities are supported transparently by T62100-SO-CR similar to adapters with external memory on them. All variants of Chelsio adapters leverage single software stack (drivers/firmware/management tools) and support all protocols concurrently.

A large portion of offloads enabled by T62100-SO-CR are based on standard TCP IP UDP protocols (such as iSCSI and iWARP) and thus can operate with a software peer or be replaced with a software solution at lower performance thus providing the requisite reliability for enterprise customers and allowing incremental installs in the datacenter. It will work with any legacy switch infrastructure and does not rely on new features such as DCB PFC ETS etc.
