LeWiz's MAGIC2020™ is an ultra high performance multi Gbps dual-port host bus adapter card with powerful on-board TCP/IP Offload Engine (LE2020™). Designed to off-load TCP/IP processing from host processor(s). It solves bottlenecks in high-performance networked systems such as servers, storage, and networked appliances. This takes the main processor(s) out of the TCP/IP loop, so that it no longer performs the major TCP/IP tasks in software.This balanced approach allows the main (host) processor to utilize most of its bandwidth to run applications. The LE2020™ accelerates the TCP/IP processing at lightning speed thus reducing network latency and overhead in network attached systems. It has the capability of handling a load of up to 256,000 concurrent connections.

TCP/IP is a protocol used to communicate server to server, server to PC, server to storage, server to network appliance, and the list of applications continues to expand. Unfortunately, TCP/IP places a very heavy burden on host CPUs. At Ethernet speeds of 10/100, most CPUs can handle the TCP/IP processing overhead. It is a standard rule of thumb that a CPU of 1KHz is required to process TCP overhead associated with transfering data 1Kbit/sec. With the advent of gigabit Ethernet, server CPUs have begun to choke while processing the TCP/IP overhead associated with transferring data. Since every Ethernet port is bi-directional that means that each port consumes 1Gbps in and 1Gbps out. So the host processor handling two ports has to run at 4GHz just to process the TCP/IP protocol. When this happens, the application that is being used, comes to a complete stop. The obvious solution is a TCP/IP Offload Engine (TOE) like the LE2020™. This chip offloads the TCP/IP processing from the host CPUs, freeing up valuable CPU cycles for application processing while maintaining the programmability, configurability, and flexibility via the host interface. It also supports fail-over protection/alternate pathing and load balancing/trunking capabilities required in high-performance server and storage systems. The result is faster servers, an accelerated network, superior application performance, saving cost and improve reliability for the enterprise network. The MAGIC2020™ card is ideal for network intensive environments, such as file serving, network attached storage (NAS), high performance technical computing, high-end backup and restore, IP storage, and video serving.

Using LeWiz's advanced layer-processing architecture, the LE2020™ offers the highest performance, lowest power and most cost effective way of addressing the performance bottlenecks found in many IP network attached equipment.
