High speed switched fabric is defined as a switching system that aims at connecting devices together with an objective to support multiple simultaneous data transfers which is basically implemented with a
crossbar switch. The data is sent in the form of packets with the help of information contained in the packet header for error detection, identification, correction and routing.
The 52xxx modules are fully compatible with Pentek's 53xxx 3U OpenVPX modules, which include a fully programmable serial fabric
crossbar switch.
Based on gate counts of
crossbar switches, the number of gates in a 2x2
crossbar switch are approximately equal to [lambda] and for a 3x3 switching element [lambda.sub.3] = 9/4 [lambda](i.e.
The technology calls for a nanoscale
crossbar switch structure to be layered on top of conventional CMOS (complementary metal oxide silicon), using an architecture HP Labs researchers have named "field programmable nanowire interconnect (FPNI)" -- a variation on the well-established FPGA technology.
The first, the TagmaStore Network Storage Controller model NSC55, delivers all of the revolutionary functionality of the TagmaStore Universal Storage Platform--including its massively parallel
crossbar switch architecture for high availability and performance; large-scale controller-based virtualization layer for ease-of-management; logical partitioning for application quality-of-service; storage-agnostic universal replication for business continuance; and a rich set of software tools.
The two-chip set consists of a queue manager that supports either two OC-192 ports or eight OC-48 ports and a
crossbar switch whose 256 Gbps of data throughput enables the industry's fastest switching performance.
To scale to terabit capacity, Cisco uses a 256x256
crossbar switch to connect multiple 12016 routers, allowing service providers to build backbone capacity incrementally.
But IBM was able to move its twelve-way clustering project (ganging up three four-ways together in an SMP using a proprietary supercomputer
crossbar switch) forward by a year and used it in the Raven servers first rather than the Blackbirds as originally planned.
