InfiniBand™

As processor speeds increase with Moore's Law and the internet drives the demand for available data, the biggest gate to improved data center performance is the I/O subsystem. InfiniBand architecture is designed to fulfill the need for greater data center reliability, availability and scalability, as well as greater design density for InfiniBand architecture enabled servers. Measurements for InfiniBand analog validation and compliance are specified in Chapters 6, 7 and 8 of the InfiniBand specification. InfiniBand employs both Low Voltage Differential Signaling (LVDS) Copper and Optical Interfaces at 2.5 Gb/s. Copper interfaces include 1X, 4X and 12X, with a maximum bit rate of 30 Gb/s.

Tektronix' comprehensive, integrated tool set - signal sources, oscilloscopes, probes and software - enables you to resolve analog validation and compliance issues quickly and efficiently so that you can easily implement InfiniBand into your designs.

High-speed Measurements Need Record Length to Match
Today's high-speed measurements demand more than just oscilloscope bandwidth; they call for a deep memory to store the results of acquisitions at sample rates up to 40 GS/s. Read this application note to understand more about record length the many applications, not just specialized, where deep memory is needed.
