Chelsio's T61100-OCP for Open Compute Project (OCP) is a memory free single port 40/50/100 Gigabit Ethernet Server Offload adapter, with PCI Express 3.0 host bus interface, optimized for cloud computing, storage, HPC, virtualization and other datacenter applications in an Open Compute Network and Storage environment.

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 T61100-OCP, 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.

T61100-OCP 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.

Open Compute Project is a rapidly growing community of engineers to design and enable the delivery of the most efficient server, storage and datacenter hardware designs for scalable computing.
