crossbar switchAn earlier telephone switch. First used in the late 1930s, it was a mechanical device that used magnets and metal bars (crossbars) to close connections. Crossbar switches have been replaced with electronic switches (large-scale, specialized computer systems). See ESS and DMS. See also crosspoint switch. |

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 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 doubling of capacity combined with the high bandwidth of Hitachi's crossbar switch architecture and virtual storage ports are key differentiators between Hitachi's products and the competition. |
