Sg1010 - Starfabric switch
The SG1010 is a cascadable 6 port StarFabric switch that connects to other StarFabric switches or bridges to create StarFabric switch fabrics. The SG1010 switch provides 30 Gbps of aggregate, non-blocking, full-duplex switching capacity through six StarFabric links. Each link can simultaneously transmit and receive at 2.5 Gbps. A standard link is made up of four aggregated 622 Mbps LVDS differential pairs in each direction. Two 2.5 Gbps full-duplex links can also be bundled to create a 5 Gbps full-duplex link.
The SG1010 supports three routing methods. Address routing, which allows PCI designs to be transparently migrated to StarFabric, supports PCI traffic over the fabric without requiring any software development. Existing PCI designs can quickly take advantage of StarFabric's performance and scalability through address routing, and can further enhance performance, features and reliability by moving to native StarFabric routing methods at a future time.
Path routing and multicast routing are StarFabric native routing methods that introduce advanced features like redundancy through failover, Quality of Service, security mechanisms and multi-processor fabrics. Dolphin provides software tools and libraries to take full advantage of these advanced features.
