LaneLink™ 4x and 12x Cable

Assemblies

4x – 74506

12x – 74509

LaneLink™ assemblies feature user friendly squeeze-to-release latch to

guarantee proper mating

LaneLink cable assemblies meet the new InfiniBand* architecture, which is an approach to I/O technology

that was created by the industry’s top computer manufacturers to address the need for greater scalability,

reliability, availability and performance in and around servers. The technology will be used to connect servers

with remote storage and networking devices, as well as other servers, through host-channel adapters (HCAs)

and target-channel adapters (TCAs).

The InfiniBand specification grew out of the merger of two earlier groups, Next-Generation I/O and Future

I/O, to become one of the enablers for industry-standard server networks. It is designed to support

bandwidths well beyond today’s prevailing I/O technologies and will run at 2.5Gbps in a single-directional

link. Scaling in bandwidth and frequency is achieved in links of 1 bit, 4 bit and 12 bit bidirectional connections

(1X, 4X and 12X). The Molex design adds desirable features, solving issues existing with competitive product.

This I/O system has been adapted by several other standards or MSA groups in addition to InfiniBand.
