MS-6E

6-Port Expandable Modular SCI Switch for System Area Networks

Dolphinґs Modular SCI Switch (MS-6E) is a high performance and affordable solution for small server clusters and system area networks.
Dolphin's Modular SCI Switch is ideally suited for enterprise clusters that require both high availability and scalability of application performance. The switch is based on a reliable design that provides both guaranteed data delivery and high-bandwidth, ultra-low

Features and Benefits · 4 x 800 MBytes/s duplex user ports, 2 x 800 MBytes/s duplex expansion ports · ANSI/IEEE 1596-1992 Scalable Coherent Interface (SCI) standard compliant · Internal Switch bandwidth: 1.28 GBytes · Port to port latency of 250 nanoseconds · Dual fans for reliability and increased circuitry lifespan · High availability clusters supported by hotpluggable links and port fencing · Front LEDs for error and activity indication · Compatible with 19" racks for ease of mounting · Autoranging power supply

latency packet switching. To maximize application scalability, the SCI Switch provides very high data throughput and low message latency. Cluster nodes connect through four duplex 400 MBytes/s ports. For scalability to even larger clusters, the MS-6E supports redundant high performance expansion ports. These ports allow up to 12 switches to be cascaded, for System Area Networks (SAN) of up to 32 ports. The MS-6E can also be configured as a standalone 6-port switch. The SCI architecture is designed to grow to as many as 64k nodes, which leaves plenty of headroom for future expansion. For high availability requirements, the SCI Switch's "port fencing" feature guarantees that a node failure will not prevent the cluster from functioning. Hot-pluggable ports allow the addition or removal of nodes without halting cluster applications. The dual expansion ports provide highly reliable redundant links. Dual fans increase MTBF and circuitry life span. The switch is built around open standards and supports the IEEE/ANSI Scalable Coherent Interface (SCI) standard and adapter cards for standard buses such as PCI and SBus.
