ASCISSA: first open interconnects for clustered systems

Enterprise servers are increasingly being created by connecting together off-the-shelf personal computer (PC) or workstation components within so-called clustered systems. For these, the technology used to link the PCs together (the interconnect) is critical in providing the performance and fault tolerance required. An open cluster solution has been developed using an interconnect based on Dolphin's peripheral component interconnect-scaleable coherent interface (PCI-SCI) adapter, SCI switch and driver software. It makes reliable, high bandwidth links available to user-level applications with very small message delay (latency). This significantly reduces the performance overhead introduced by the interconnect itself when passing messages between nodes (the most critical interconnect requirement for effective clustered systems) as well as for block transfers. The solution is open, with a portable base platform allowing easy integration to various applications, and is scaleable to meet the requirements of different systems.
