  2. Serial Switched Fabric Technologies Common characteristics of Technologies...- Unidirectional (duplex pair)- LVDS (Low Voltage Differential Signaling)- GHz raw link speed (10Gbps by bonding links)- Open market standards- Most are VXS (VITA 41) enabledDifferences between Technologies...- InfiniBand is shipping in quantity, but limited market penetration- StarFabric is viable, but link speed limited to one-fourth of others- HyperTransport has achieved acceptance, but constrained to In-the-Box - RapidIO has both Serial and Parallel, but lacks silicon (some parallel)- PCI Express has PCI lineage/momentum, but no products until 2004.- PCI Express Advanced Switching (AS) is not specified.- Gigabit Ethernet is TCP/IP leader, but stack is CPU intensive (Need TOE)- 10 Gigabit Ethernet products are now emerging.
