The SBus-SCI adapter card is a high performance dedicated clustering solution for compute intensive and communication intensive applications. The SBus-2B card is a high performance solution for clustering of SPARC systems. Applications include clusters of systems for compute processing and high availability database operations. The SBus-2B card uses fast point-to-point links and reliable protocols to overcome limitations of traditional network solutions. With the use of shared memory, applications can bypass time consuming operating systems calls when sending small messages between nodes. The adapter also supports fast DMA transfers from user memory to user memory. Systems within a cluster can be connected in a ring or by use of a switch. Use of multiple adapters enables redundant links for systems that require fault tolerant operation. Features and Benefits ANSI/IEEE 1596-1992 Scalable Coherent Interface (SCI) standard compliant Ultra-low latency (less than 4µs) in combination with high bandwidth operation. Efficiently supports clustering applications Compatible with Sun SPARC desktop and server systems Cost-effective scalability from two to many nodes Supports both Direct Memory Access (DMA) and Remote Memory Access (RMA) Reliable operation with support for redundant
