Eclipse - iSCSI Communication Processor

Eclipse is a complete system on a chip for supporting the Ethernet iSCSI protocol. Eclipse is based on VLSI integration of physical device interface required for communicating with other Ethernet devices without CPU intervention from an outside source. This device contains the circuitry required for Internet Protocol (IP) hardware automation by using a two embedded RISC processors. The main internal processor is a 64 bit MIPs processor running at 300MIPs. This processor is running the industry standard Linux operating system. The other processor is a dedicated iSCSI/MAC processor used to manage the IP packets in firmware for supporting iSCSI protocols.

This chip can be used as a host controller chip for the workstation or server system. It can also be used as a host controller chip for a disk RAID system. In a NAS environment, this system chip provides a data path for delivering data to the serial ATA SAN disk drives for true SAN performance within a NAS system. Since iSCSI is over a standard Ehternet 802.3 system, the Eclipse chip can also perform standard Network File System services.
