Chelsio is a leading technology company focused on solving high performance networking and storage challenges for virtualized enterprise data centers, cloud service installations, and cluster computing environments. Now shipping its fifth generation protocol acceleration technology, Chelsio is delivering hardware and software solutions including Unified Wire Ethernet network adapter cards, unified storage software, high performance storage gateways, unified management software, bypass cards, and other solutions focused on specialized applications.

Unified Wire Adapters

Chelsio’s Unified Wire Adapters accelerate network performance in enterprise data centers, cloud services and high performance clusters(HPC).

Designed for deployment in virtualized data centers, cloud service installations and high performance computing environments, Chelsio Unified Wire adapters bring a new level of performance metrics and functional capabilities to the computer networking industry.

Specialty Adapters

Chelsio Bypass Adapters enable intrusion prevention/business continuity, WAN optimized TCP offload, load balancing and inline and wire speed analytics.

With four operational modes (bypass, normal, drop and selective bypass), Chelsio Bypass Adapters enable intrusion prevention/business continuity, WAN optimized TCP offload, load balancing and inline and wire speed analytics.

Chelsio’s Unified Storage Motherboard is a single board computer which creates a storage subsystem consisting of up to 24 SAS disks which are accessible via Ethernet as a SAN or NAS.


Chelsio’s Unified Storage Router(USR) is a cost-effective solution to improved FC SAN and SAS storage utilization

In mid-range and enterprise businesses, rapid growth increases the cost of operations and spreads critical business data and resources across multiple systems and applications. Chelsio’s USR-1100 extends the existing storage investment with the ability to integrate low-cost Ethernet-connected servers into the SAN, without requiring additional storage arrays or management costs.

Chelsio’s pre-certified configurations enable high performance storage for the most demanding applications, including scalable cloud storage and HPC distributed storage.


Unified Storage Server is a powerful turnkey solution for creating high-performance storage systems.

It is an integrated solution that is best-of-breed in the market, and provides an easy integration path for VARs and OEMs, and offers state-of-the-art performance and ease-of-use for end users.

Unified Manager centrally manages all Chelsio network adapter cards on the network across Windows and Linux environments.

Chelsio Unified Manager includes an intuitive user interface through its graphical user interface (GUI) or through the command line interface (CLI) tool.

Target Protocol Software delivers high-performance iSCSI target-mode functionality.

The software applies Chelsio’s iSCSI acceleration technology to CPU-intensive iSCSI operations, resulting in exceptional performance at optimum CPU utilization.

StreamEngine software significantly reduces CPU utilization and increases video and content delivery capacity.

Chelsio StreamEngine (CSE) adds video segmentation offload and per-stream rate shaping functionality to the TCP and UDP offload capabilities of the T5 Unified Wire adapters. This enables best-in-class performance for Content Delivery Networks (CDN), IPTV and Video on Demand providers.

Virtual Uplink Software is a new driver that gives users of VMware ESX 4.0 the flexibility for virtual consolidation of existing Gigabit links over Chelsio 10Gb Unified Wire adapters.

WireDirect enables direct wire access from user space to the Chelsio T5 network adapter with complete bypass of the kernel, resulting in a 10Gb Ethernet solution with an ultra-low latency.


T5 is Chelsio’s fifth generation ASIC that provides no-compromise performance with both low latency (1usec through hardware) and high bandwidth.
