While the InfiniBand industry continues to shrink, a start-up recently introduced an entry-level clustering device that uses the next-generation bus.Topspin's introduction of the Topspin 90 Switched Computing System follows Banderacom's announcement that it will refocus on Gigabit Ethernet silicon instead.The Topspin 90 Switched Computing System interconnects InfiniBand-clustered servers with Gigabit Ethernet networks and Fibre Channel storage-area networks. It is similar to a switch Omegaband had planned before it ceased doing business two months ago.The Topspin 90 is a 1U-high rack-mountable switch that has as many as 16 InfiniBand ports. These ports can be intermixed in a variety of configurations with Gigabit Ethernet or 2G bit\/sec Fibre Channel ports.A starting configuration consists of 12 ports of 10G bit\/sec InfiniBand. Customers can add four additional InfiniBand ports, two Fibre Channel ports or four Gigabit Ethernet ports by simply inserting an expansion module.The Topspin 90 has a management interface in common with Topspin's larger product, the Topspin 360. It can be managed from a graphical interface or a command-line interface using the serial port and Telnet or SSH. It is also SNMP-manageable.A 12-port Topspin 90 starts at $12,000 and is available now.
