ECHNOLOGY
InSpeed technology is an advanced switching architecture that couples a non-blocking crossbar switch
with a unique switch port logic and per-port SERDES. This results in the industry’s highest density Fibre
Channel switch on a chip (SOC). The port logic is based on Fibre Channel-Arbitrated Loop (FC-AL), an
ANSI standard (X3T11) designed to provide shared bandwidth over low-cost media.
This architecture enables the switch’s router to send data directly from one port to another, allowing for
multiple, simultaneous conversations between ports—effectively multiplying bandwidth. InSpeed™
provides the same performance as complex fabric switches that support FC-SW2. InSpeed™ can even
exceed fabric switch performance in entry-level SAN environments, where the overhead associated with
longer name addressing and services is not beneficial.
