Cisco is buying Topspin Communications for $250m (£133m).
The acquisition gives the networking giant access to Topspin's switches, which are used to help companies assemble their servers into computing clusters and link them to networks and storage systems. These "server fabric switches" are designed to provide data centres with high-performance networking service in areas such as grid computing, clustered applications and server virtualisation.
Topspin uses the high-speed InfiniBand technology, which after a slow start has become an increasingly common ingredient in supercomputers built out of a number of low-end systems. Among the company's customers is Dell, which sells its PowerEdge 1850 servers connected into groups of eight, 16, 32, 64 and 128 connected by TopSpin's switches.
With the deal, Cisco is filling out its array of switching products, which also includes Ethernet gear for Internet and intranet connections and multiprotocol MDS switches for SANs.
"The widespread adoption of server architectures such as blades, grid computing, and clustered applications is driving an emerging market opportunity within the data centre," Luca Cafiero, a senior vice-president at Cisco, said in a statement. "As our customers build out these new computing environments, it is important that we deliver server networking technologies to fit their needs."
The deal, which involves both cash and options, is expected to close in Cisco's fourth fiscal quarter, which ends on 30 July. Earlier this month, the company agreed to buy Concord Communications, a maker of network service management software, for $350m.
Five-year-old Topspin has approximately 135 employees in Mountain View, California, and Bangalore, India.
